Advantages:
Good toughness at lower hardness lever.
Good wear at high hardness lever.
Application:
L6 was designed for general purpose tools where greater toughness is required, such as forming rolls, punches, blanking dies, shear blades,and spindles.
Machinability:
L6 has a machinability rating of 85% of a 1% carbon tool steel.
Annealing:
L6 should be annealed at 1400°F and held for one hour per inch of thickness. Cool at 20°F per hour to 900°F and then air-cool. A maximum hardness of 217 Brinell should be obtained.
Hardening:
L6 should be preheated to 1200°F then heated to 1500°to 1550°F and held for one hour per inch of thickness. Quench in oil to 150°F followed immediately by tempering. L6 can also be air quenched in sections less than 1" thick.
