Material

AISI A-2

An air or oil hardening tool steel offering an excellent combination of wear resistance and toughness.


HARDENING:


Preheating Temperature: 1200-1300 ° F (650-750 ° C)


Austenitizing Temperature: 1690-1780 ° F (925-970 ° C)


Hold for 30 minutes once the entire tool reaches temperature. 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 tempering 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.
