Large-Section Open Die Forgings
Open die forging is the process of deforming a heated workpiece between flat or simple shaped dies to achieve the desired cross-section and length. It produces components with exceptional grain refinement, improved mechanical properties and internal soundness across the full section.
Open Die Forged Components
Forged Discs & Rings
Open die forged discs and ring blanks for flanges, gear blanks and structural parts.
Stepped Shafts
Large stepped shafts forged to near-net profile for industrial machinery.
Cylinders & Sleeves
Open die forged cylinders and sleeves for hydraulic and pressure vessel applications.
Forged Blocks
Rectangular and square forged blocks for tooling, dies and structural applications.
Custom Open Die Shapes
Any cross-section profile forged to customer drawing and specification.
Open Die Forging Materials
Alloy Steel (42CrMo4, EN19)
Primary alloy steel for open die forged shafts and industrial components.
EN24 / SAE 4340
High-strength alloy for large industrial and heavy engineering open die forgings.
Carbon Steel (C45, C55)
Carbon steel open die forged rounds and bars for general machining stock.
Tool Steel (H13, D2)
Tool steel billets forged for die and mould manufacturing applications.
Stainless Steel Grades
Open die forged stainless bars and discs for corrosive environment applications.
Custom Grade Billets
Any material grade forged to customer billet or shape specification.
Open Die vs Closed Die Forging
No Die Tooling Cost
Open die forging requires no custom dies, ideal for prototypes and low-volume shapes.
Large Cross-Sections
Suitable for large diameters and heavy sections not feasible by closed die.
Grain Refinement
Repeated working refines grain structure throughout the entire cross-section.
Internal Soundness
Repeated reduction closes internal porosity in ingots and continuous cast billets.
Flexible Shapes
Rounds, squares, rectangles, steps and flanged profiles achievable without tooling.
Material Efficiency
Near-net shaping reduces machining allowance vs starting from standard mill bar.
Large-Section Open Die Forgings
Shivam Forge is a capable open die forging manufacturer in India producing large-section forged bars, discs, stepped shafts, cylinders and custom profiles for heavy engineering, power, oil and gas, tooling and industrial applications. Our open die forging capability complements our closed die forging to cover the full range of forged component requirements.
Open die forging — also known as free forging or smith forging — deforms heated metal between flat or simple dies without enclosing the workpiece. This process is ideal for large cross-sections, custom profiles, stepped shafts and prototype quantities where closed die tooling is not economical. The repeated working of the material refines grain structure and closes internal porosity throughout the full section.
Our open die forging capability allows us to produce forged bars, rounds, discs and shapes in alloy steel, carbon steel, tool steel and stainless steel grades. Post-forging heat treatment develops the required mechanical properties, and our CNC machining capability can further machine open die forgings to closer tolerances.
Shivam Forge serves heavy industry, power generation, tooling manufacturers and custom engineering projects with open die forged components. Whether you need a single prototype forging or a series of heavy forged billets, our open die forging capability provides a cost-effective solution with superior material properties versus rolled or cast alternatives.
Frequently Asked Questions
What is open die forging?
Open die forging is a process where heated metal is shaped by repeated blows between flat or contoured dies without enclosing the workpiece. It is used for large sections, stepped shafts, discs and custom profiles.
What open die forged products does Shivam Forge manufacture?
We produce forged bars, rounds, discs, ring blanks, stepped shafts, cylinders, sleeves, blocks and custom open die shapes in a range of steel grades.
What is the advantage of open die forging over rolled bar?
Open die forging refines grain structure, closes internal porosity, and achieves custom cross-sections and stepped profiles not available in rolled bar at equivalent mechanical properties.
What materials can be open die forged?
We open die forge alloy steel (42CrMo4, EN19, EN24, SAE 4340), carbon steel (C45, C55), tool steel (H13, D2) and stainless steel grades.
Is open die forging suitable for prototype or low-volume requirements?
Yes. Open die forging requires no custom tooling, making it cost-effective for prototype, development and low-volume requirements where closed die tooling investment is not justified.
What sizes and weights can you open die forge?
Contact us with your size, cross-section and weight requirements for a feasibility assessment and quotation.
Do you heat treat open die forgings?
Yes. We provide normalizing, hardening, tempering and annealing for open die forged components to achieve required mechanical properties.
Can you produce stepped shaft forgings by open die forging?
Yes. Open die forging can produce stepped shaft profiles with multiple diameters and lengths, reducing machining from bar to near-net shape.
Do you supply forged bar stock for machining shops?
Yes. We supply forged alloy and carbon steel bars and rounds as machining stock with superior mechanical properties versus rolled bar.
How do I request an open die forging quotation?
Share your material grade, cross-section dimensions, length, weight and quantity for a quotation within 24 hours.
