Steel Ingots for Open Die Forging
Open die forging shapes a heated ingot between flat or shaped dies, drawing it out, upsetting it and cutting it to size. It makes the heaviest forgings, so it starts from cast ingots.
Steel ingots for open die forging are cast square, fluted or round, with a hot top, from M1.5 to M22, vacuum degassed and bottom poured.
Typical components
- Shafts and rotors
- Rings and discs
- Forged blocks
- Hollow forgings
Recommended steel grades
EN8
General-purpose medium carbon steel with a good balance of strength and machinability. It responds to quenching and tempering in small and medium sections.
EN19
A widely used chrome-moly steel with good hardenability, toughness and fatigue strength in the quenched and tempered condition.
EN24
A high strength, deep hardening steel with very good toughness, used where heavy sections must harden right through.
SAE 4140
The American-designation counterpart of EN19 and 42CrMo4. Strong, tough and easy to heat treat.
SAE 4340
A tough, high strength steel with excellent hardenability. Often chosen for heavy-duty, shock-loaded parts.
Choosing the ingot
Tell us the finished weight and the forging route so the ingot mark and shape can be matched. See the guide on ingot selection for open die forging.
Check the ingot size chart for available marks and weights, and read how to choose the right ingot size using the forging reduction ratio.
