Product Description

Product Description

DIN 1.2842 O2 9Mn2V SKS93 Die Steel Tool Forged Steel Round Bar

1: AISI O2 Steel Introduction

    AISI O2 tool steel is an oil hardening tool steel which is supplied in the annealed condition and characterised by its characteristics of offering good durability. Tool steel O2 is with excellent wear resistance and its ability to hold a good cutting edge. 02 steel is a good quality general purpose tool steel often used where the expense of a high carbon high chromium tool steel would not be justified.
