Material
AISI O-1
A general-purpose oil-hardening tool steel that is versatile and suitable for a wide variety of cold work applications.
HARDENING:
Preheating Temperature: 1110-1290 ° F (600-700 ° C)
Austenitizing Temperature: 1450-1560 ° F (790-850 ° C)
Protect the part against decarburization and oxidation during hardening. Quench as quickly as possible. Cooling must be uniform and at a rate to avoid distortion and/or quench cracking. Choose the temperature from the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest temperature 360 ° F (180 ° C). Holding time at temperature minimum 2 hours.
Available in 18” and 36” lengths.
