DC-53
AISI - A2
An air-hardening tool steel containing five percent chromium. Replaces the
oil hardening (O1 type) when safer hardening, less distortion and increased
wear-resistance are required. Provides an intermediate grade between the oil
hardening and the high carbon, high chromium (D2) types.
AISI A6
A6 is an air-hardening, non-deforming tool steel that combines the deep hardening
characteristics of air-hardening steels with the simplicity of low temperature
heat treatment possible in many of the oil-hardening grades.
AISI D2
D2 is an air-hardening, high carbon, high chromium tool steel with extremely high wear
resisting properties. It is a very deep hardening steel and will be practically free from
size change after proper treatment. The high percentage of chromium gives it mild
corrosion-resisting properties in the hardened condition.
DC53
DC53 is a general purpose, cold work die and mold steel whose strength and toughness
approach those of high-speed steels.
