CarTech O1 Steel

CarTech O1 Steel

Steel name: CarTech O1
Diagram No.: 2299
UNS designation: T31501
AISI/SAE designation: O1
Chemical composition in weight %: 0.90% C, 1.20% Mn, 0.50% Cr, 8.00% Mo, 0.20% V, 0.50% W
Steel group: Tool steels
Properties: CarTech 01 is a manganese-chromium-tungsten, nondeforming, oil hardening general purpose tool and die steel which is safe to harden, even in intricate sections.
Applications: Blanking dies, forming dies, lamination dies, molding dies, trimming dies, broaches, collets, stamps, master tools, spindles, master taps, thread gauges.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 01 may be hardened from temperatures between 1450/1500°F (788/816°C). Endothermic atmospheres should be held to dew point limits between 45/55°F (7/18°C). This wide hardening range makes it possible to fit into many heat treating schedules during the average day. This broad a hardening range supersedes all other references to 01 hardening temperatures previously published.
Tempering: Temper 01 immediately to the desired hardness level. The minimum tempering time is 1 hour at temperature. Be sure to allow sufficient time to allow the material to reach the proper temperature. Sections over 2 inches thick should be tempered one hour per inch.
