AISI 12L14 Forging Capabilities
AISI 12L14 Forging Capabilities
(OP)
Hi all,
I am unfamiliar with the forging capabilites of AISI 12L14. I would like to know if there are any issues with forging this particular carbon steel. The reason I ask is because a supplier of ours is requesting a material change request stating that the material is too soft for forge forming. He is advising us to use 1020. I do understand that 12L14 is a relatively ductile and soft material primarily due to the lead content thus making a free-cutting material. Also, I believe I read somewhere that the minimun carbon content for forging is 0.3% whereas 12L14 has a carbon content of ≤ .15%. Here are it's chemical properties from SAE J403 for reference.
Fe: 97.91 - 98.70%
C: 0.15% Max
Mn: 0.85 - 1.15%
P: 0.04 - 0.09%
S: 0.26 - 0.35%
Pb: 0.15 - 0.35%
Any suggestions or recommendations are greatly appreciated. Thanks in advance.

Hot shortness is the term used to describe the condition of poor ductility at hot working temperatures due to certain alloying elements in steel (copper, lead, etc.). 12L14 is definitely not a suitable forging alloy. If the part isn't being machined completely out of cold drawn bar, don't specify this alloy.
