Product Description

O1 | 1.2510 | 100MnCrW4 | SKS3 Tool Steel



1: O1 steel introduction

AISI / ASTM A681 O1 tool steel is a low alloy cold work tool steel that must be oil-quenched in heat treatment. Tools and dies made from O1 tool steel flat or rounds will have good wearing and abrasive qualities since the tungsten and higher chromium content gives improved wear resistance.

ASTM O1 tool steel has deep hardening properties with fine grain structure with unusual toughness. AISI O1 tool steel offers good durability, gives excellent wear resistance and holds a good cutting edge. O1 cold work tool steels also has good response to heat treatment with small dimensional changes.
