Forged parts by industry and application
Each industry brings its own parts, alloys and paperwork. Put the spec, test and certificate requirements in your RFQ so we match forging suppliers that already work to them.
Oil and gas
Pressure containing parts that must hold under load, heat and corrosive service.
- Typical partsFlanges, valve bodies, wellhead parts and fittings.
- Usual materialsCarbon and low alloy steel, stainless, duplex and nickel alloys.
- Usual processClosed die, open die and rolled ring.
- PaperworkASTM A105 or A182, API 6A or 20B for wellhead parts, NACE MR0175 for sour service, 3.1 certificates, UT and MPI.
Power generation
Large rotating and pressure parts that run hot for years.
- Typical partsTurbine discs, shafts, rings and pressure parts.
- Usual materialsChrome molybdenum alloy steel, stainless and nickel alloys.
- Usual processOpen die and rolled ring.
- PaperworkMechanical test results, ultrasonic testing to ASTM A388, heat treatment records and traceability to the heat.
Heavy equipment
Parts that take shock and wear in construction and earthmoving machines.
- Typical partsTrack links, sprockets, pins, hubs and lifting points.
- Usual materialsMedium carbon and alloy steel such as 4140 and 4340.
- Usual processClosed die and open die.
- PaperworkHardness and heat treatment requirements, and magnetic particle inspection on critical parts.
Automotive and truck
High-volume parts where tolerance, weight and cost per piece all count.
- Typical partsCrankshafts, connecting rods, steering knuckles, axle parts and gears.
- Usual materialsMedium carbon and alloy steel, microalloyed steel, and aluminum for suspension.
- Usual processClosed die, plus warm and cold forging for small parts.
- PaperworkMany buyers ask for an IATF 16949 quality system, sample approval and part marking.
Aerospace
Lightweight, high-strength parts with full records behind every lot.
- Typical partsStructural fittings, landing gear parts, engine discs and rings.
- Usual materialsAluminum 7075, Ti-6Al-4V, Inconel 718 and high-strength steel.
- Usual processClosed die, open die and rolled ring.
- PaperworkMany buyers ask for AS9100, AMS specs, customer-approved process sources and lot traceability.
Mining
Wear and shock loads on crushers, mills and haul equipment.
- Typical partsWear parts, shafts and large rings for crushers and mills.
- Usual materialsAlloy steel and high-strength carbon steel.
- Usual processOpen die and rolled ring.
- PaperworkHardness values, and ultrasonic testing on large shafts.

Rail
Safety critical rolling stock parts made to published standards.
- Typical partsAxles, wheels, couplers and suspension parts.
- Usual materialsCarbon and alloy steel.
- Usual processClosed die, open die and rolled ring.
- PaperworkEN 13261 for axles and EN 13262 for wheels in Europe. AAR specifications in North America.
Hydraulics
Parts that carry pressure and cyclic load in cylinders and valve blocks.
- Typical partsCylinder ends, clevises, rod eyes and manifold blocks.
- Usual materialsCarbon and alloy steel, and stainless.
- Usual processClosed die and open die.
- PaperworkPressure rating, hardness and magnetic particle inspection on stressed parts.
Rigging and lifting
Parts that must carry a stated working load without failure.
- Typical partsHooks, shackles, eye bolts and turnbuckles.
- Usual materialsCarbon and alloy steel.
- Usual processClosed die.
- PaperworkProof load testing, batch traceability and working load limit marking.
Hand tools
High-volume forged tools where hardness and finish decide the quality.
- Typical partsWrenches, hammers, pliers and sockets.
- Usual materialsMedium carbon steel and chrome vanadium steel.
- Usual processClosed die, and warm or cold forging for small sizes.
- PaperworkHardness range, surface finish or plating, and torque or proof tests for the tool standard.
Questions about forged parts by industry
My industry is not listed. Can I still send an RFQ?
Yes. The industry matters less than the process, alloy, weight and the tests you need. Send the drawing and list the specs you work to.
Does a supplier need a certification for my industry?
It depends on your end customer. Some industries expect a quality system such as IATF 16949 or AS9100, and many parts only need material and test certificates. Put your requirement on the RFQ and we match shops that list it. Ask for a copy of the certificate before you order.
Can you match suppliers for safety critical parts?
Yes, but say so on the RFQ. Safety critical parts usually need traceability, non-destructive testing and a named test standard, and these change which suppliers fit.
Need a quote for your part?
Send the drawing with the specs and certificates you need. We match up to 3 suppliers and reply within 24 business hours.
