AISI O1 Cold Work Mold Steel
1: AISI O1 steel introduction
AISI O1 tool steel is a low alloy cold work tool steel that must be oil-quenched in heat treatment. Tools and dies made from AISI O1 tool steel flat or rounds will have good wearing and abrasive qualities since the tungsten and higher chromium content gives improved wear resistance. AISI 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. AISI O1 cold work tool steels also has good response to heat treatment with small dimensional changes.
