Hot Forging Supply to Kolkata — Power, Railways, Mining & Heavy Engineering
Shivam Forge supplies forged components to Kolkata's heavy engineering, power and mining sectors from our Shapar, Rajkot factory. BHEL Titagarh turbine and boiler components, Titagarh Wagons railway bogies, DVC and WBSETCL power infrastructure and Coal India mining equipment — we produce these in power plant grades (F22, F11, P91), railway steels (IS 1875, IS 2004), mining wear steel (Mn13, EN25) and IBR-approved materials (SA 516 Gr 70, SA 182 F1/F11). Rail and air freight from Rajkot cover the 2,000 km corridor reliably.
Kolkata anchors East India's heavy engineering and industrial manufacturing. BHEL Titagarh builds turbines and boilers; Titagarh Wagons manufactures railway freight wagons; Coal India, DVC and WBSETCL manage India's largest coal and power infrastructure. These industries need forgings with documented IBR approval, ASTM material certifications, and mill-traceable heat numbers — documentation standards that most small forging shops cannot support. From Rajkot, we supply Kolkata with air freight in under 24 hours for urgent components and rail freight for bulk consignments. Call +91-9265772827 to discuss power, mining or railway forging requirements.
BHEL Titagarh manufactures steam turbines, boilers and transformers. Forging requirements include turbine shaft blanks, diaphragm rings, valve body forgings, flange and nozzle forgings in Cr-Mo grades F11 and F22, plus SA 105 pressure vessel flanges. IBR form approval and third-party inspection witness (EN 10204:2004 3.2) are standard for BHEL power forgings.
Titagarh Wagons and ICF wagon builders need axle blanks, bogie side frame bracket forgings, draft gear housing components and coupler knuckle forgings. IS 1875 axle steel and IS 2004 Grade 2 structural steel are the primary grades. Railway forgings require RDSO-approved material certs and dimensional inspection reports.
Coal India's Kolkata headquarters and West Bengal / Jharkhand coalfield equipment suppliers need robust wear-resistant forgings — dragline bucket teeth, ripper shanks, sheave pins, conveyor coupling forgings and hydraulic cylinder end caps. Hadfield Mn13 and SAE 4340 are standard grades; hardness certification is mandatory.
Damodar Valley Corporation and West Bengal State Electricity Transmission Company procure valve body forgings, pipe flange sets, pump shaft forgings and pressure vessel nozzle blocks for thermal and hydro power stations. These require IBR-compatible material grades and inspection to boiler and pressure vessel codes.
Kolkata and Haldia port handling equipment — crane hooks, shackle forgings, spreader bar fittings, chain coupling links and mooring hardware — requires forged components with EN 10204:2004 3.1 certs and third-party NDT. We forge these in EN25T, IS 2062 and stainless 316 as required.
EPC contractors and capital equipment fabricators in Kolkata need structural forgings, equipment brackets, flanged nozzles and shaft forgings for a range of industrial plant. We supply these as per drawing with certified material and dimensional inspection reports, typically on 3–4 week lead times.
For urgent components — a replacement valve body forging, a shaft blank needed to keep a turbine overhaul on schedule — Rajkot to Kolkata airport is a 2-hour flight, with same-day or next-day cargo connections through IndiGo and Air India Cargo. Air freight landed cost is offset by the value of avoiding plant downtime.
The Rajkot–Howrah rail route via Okha-Howrah Express carries goods in approximately 48 hours. For bulk forging consignments — wagon axle blanks, bulk flange batches, mining wear parts — rail freight per tonne is significantly cheaper than road and tracks reliably through FOIS. We arrange freight booking and provide RR details to customers.
IBR approval under the Indian Boiler Regulations requires specific material grades (SA 105, SA 182 F1/F11/F22) with EN 10204:2004 3.2 certificates witnessed by a third-party inspection authority. We arrange TPIA witness inspection through accredited agencies (Bureau Veritas, SGS, CEIL) for IBR-qualified forgings.
Mining wear forgings in Hadfield Mn13 and SAE 4340 are a regular part of our production. Mn13 components are solution-annealed to achieve austenitic structure before dispatch, confirmed by hardness and microstructure check. Impact and wear resistance test results are available for development samples.
Local West Bengal forging capacity is limited and concentrated in heavy, lower-precision segments. Rajkot's competitive industrial cost base delivers forgings to Kolkata at prices that compare favourably after freight — particularly for alloy steel and stainless grades where Rajkot vendors have better material procurement access.
We produce documentation to BHEL's standard supplier requirements: IBR Form II/III for pressure parts, ASME Section II material compliance statements, IS 2002 test certificates for forged steel pressure vessel components. Our QC team is familiar with BHEL's supplier audit checklist and process documentation requirements.
ASTM A182 F22 (2.25Cr-1Mo) and F11 (1.25Cr-0.5Mo) for high-temperature valve and flange forgings. P91 (9Cr-1Mo-V) for ultra-supercritical boiler components above 565°C service temperature. SA 105 carbon steel for standard pressure vessel flanges and nozzles. All supplied with EN 10204 3.1 or 3.2 certs.
IS 1875 axle steel (Grade 2 and Grade 4) for railway wheel-set axle blanks to RDSO specification. IS 2004 Grade 2 for structural wagon bracket and bogie frame forgings. We maintain RDSO-approved supplier documentation and produce ultrasonic test (UT) certified axle blanks on request.
Hadfield austenitic manganese steel (Mn13) for bucket teeth, crusher jaw inserts and dragline wear liners — supplied solution-annealed with hardness at 180–220 BHN, work-hardening to 500+ BHN in service. SAE 4340 and EN25 for structural mining equipment pins and coupling forgings requiring high tensile strength.
SS 316L and Duplex 2205 (UNS S32205) for Kolkata and Haldia port and shipyard hardware — shackle pins, mooring brackets, chain plate forgings and marine valve bodies. Stainless forgings are supplied with PREN calculation confirmation for chloride service environments and delta ferrite content check for duplex grades.
EN24T (817M40) for EPC and capital equipment shafts, couplings and structural pins. EN25T for higher tensile applications above 1000 MPa. C45 (080M46) for medium-duty machine components and general engineering shafts. All supplied Q&T condition with full mechanical test reports.
SA 516 Grade 70 carbon steel for pressure vessel shell plate forgings and flanged nozzles. SA 182 F1 and F11 alloy steel for high-temperature flanges and fittings. IBR approval requires material test reports verified by IBR-authorised boiler inspector. We facilitate this through our established TPIA relationships.
Kolkata has anchored East India's heavy engineering sector since the industrial era — BHEL Titagarh's turbine and boiler manufacturing, Titagarh Wagons' railway wagon production, Graphite India's electrode manufacturing and Coal India's headquarters procurement covering the entire Bengal-Jharkhand coalfield. These industries share a common requirement: forgings with traceable mill chemistry, documented heat treatment, and inspection certificates from approved third-party agencies. This is a documentation-intensive supply environment, and most small forging shops cannot navigate it. Shivam Forge has accumulated the process knowledge, material grade familiarity and TPIA relationships needed to supply Kolkata's heavy industries compliantly.
Distance from Rajkot to Kolkata runs approximately 2,000 km. Road freight takes 36–40 hours — feasible for planned procurement but not for urgent breakdown replacements. Rail freight via the Okha-Howrah Express route delivers bulk consignments in approximately 48 hours at significantly lower cost per tonne than road, and FOIS tracking provides end-to-end consignment visibility. For genuine urgency — a turbine outage waiting on a valve body forging, a wagon assembly line halted for a bogie bracket — Rajkot to Kolkata airport is 2 hours by air with same-day cargo uplift, delivering to Kolkata within 24 hours of dispatch. We arrange freight in all three modes and advise based on your lead time and volume.
The material grades required by Kolkata's industries sit in the specialty end of the forging grade portfolio. BHEL power forgings require ASTM A182 F11 and F22 Cr-Mo alloys, P91 for ultra-supercritical applications, and SA 105 for standard pressure flanges — all with IBR form approval and EN 10204:2004 3.2 certificates. Railway applications use IS 1875 axle steel and IS 2004 Grade 2 to RDSO specification. Mining wear applications demand Hadfield Mn13 austenitic manganese steel supplied in correctly solution-annealed condition. We maintain billet stock in these grades and have established material certification chains with primary steel mills.
Cost competitiveness from Rajkot is real despite the freight distance. West Bengal's forging sector is concentrated in heavy, lower-precision segments and lacks the alloy steel grade variety that Rajkot's broader industrial cluster supports. For alloy steel forgings in F22, P91, EN25T or Duplex 2205, Rajkot-sourced supply delivered to Kolkata competes on total delivered cost against local alternatives — particularly when the quality documentation requirement eliminates most small local shops from consideration. EPC contractors and large OEMs frequently dual-source from Rajkot precisely because it provides reliable capacity that local supply cannot match during peak project phases.

Air freight (cargo): under 24 hours Rajkot to Kolkata airport. Road freight: 36–40 hours door-to-door. Rail freight: approximately 48 hours via Okha-Howrah rail route. For bulk consignments, rail freight is cost-effective and traceable through FOIS. For urgent breakdown replacements, air freight is the fastest option. We arrange all three modes depending on your timeline and volume.
Yes. We produce forgings in IBR-qualifying material grades — SA 105, SA 182 F11/F22, P91 — with EN 10204:2004 3.2 certificates witnessed by approved TPIA (Bureau Veritas, SGS or CEIL on request). BHEL Titagarh's standard documentation requirements including IBR Form II/III, ASME material compliance and IS 2002 test reports are familiar to our QC team.
For bulk consignments — wagon axle blanks, flange batches, mining wear parts above 500 kg total weight — rail freight is typically cheaper and more reliable than road for the Rajkot-to-Kolkata distance. The Okha-Howrah Express route covers the distance in approximately 48 hours. Road freight (36–40 hours) is preferred for time-sensitive or dimensional-precision parts where handling is a concern. We advise on the best mode based on your specific consignment.
Yes. Mining wear forgings are a regular product for us. Hadfield Mn13 austenitic manganese steel is supplied in solution-annealed condition at 180–220 BHN, work-hardening to above 500 BHN in abrasive service. SAE 4340 and EN25 are used for structural pins and couplings requiring high tensile strength. Chemical analysis, hardness test and impact test certificates are included.
For power plant applications we produce forgings in ASTM A182 F22 (2.25Cr-1Mo), F11 (1.25Cr-0.5Mo) and P91 (9Cr-1Mo-V) for high-temperature service, SA 105 for standard pressure vessel flanges and SA 516 Gr 70 for pressure vessel components. All power plant forgings are supplied with EN 10204:2004 3.1 or 3.2 certificates as required by the inspection authority.
MOQ is flexible and depends on component weight and complexity. Small forgings under 2 kg: MOQ 100 pieces. Medium components 2–25 kg: MOQ 25 pieces. Large forgings above 25 kg: MOQ 5–10 pieces. For one-off or urgent replacement components (turbine valve bodies, shaft blanks), we accept single-piece orders at appropriate pricing. Contact +91-9265772827 to discuss.
