Shop our selection of O1 Tool Steel for excellent accuracy when being heat treated. Available in rectangle and square bar, and drill rod at OnlineMetals.com.
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.
O1 tool steel meets a wide range of characteristics including good machinability, good dimensional stability when hardened, good cutting edge retention as well as a good combination of high surface hardness and toughness after hardening and tempering.
O1 Tool Steel. O1 Tool Steel is the original oil-hardening, “non-shrinking” tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance.
AISI O1 tool steel is a low alloy type cold work tool steel, containing manganese, chromium and tungsten, which must be hardened by oil quenching. It is by far the most widely used tool steel and is produced by almost all tool steel mills.
O1 Tool Steel is an oil-hardening, “non-shrinking” and versatile tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 Tool Steel is known as a low alloy steel because it contains several additives. O1 steel is in compliance with SAE J437 and J438, ASTM A681, and DIN 1.2510.
