It is a medium alloy cold work steel containing approximately 1% carbon.
It is a medium alloy steel that can harden in oil and has high expansion properties.
It has a high hardening ability towards the core. It is dimensionally stable and has
good compressive strength. Wear resistance is low. It is also known as oil steel.
It has similarity to AISI 02 and 2510 steel.
