製品説明

Products Description

DIN12631 / AISI A8 is a kind of medium carbon & air hardened cold work tool steel with excellent toughness, medium wear resistance and excellent dimensional stability after heat treatment. A punch that has been used in the hardness range 55 to 60 Rockwell C. It is more ductile than A-2 or D-2, more wear-resistant than S-7, and very stable in heat treatment.
