particularly used for pivot pins, dental and surgical instruments, valve parts.

Heat treatment

Hardening

Preheat to 1400/1500°F ( 760/816°C ), then heat to 1850/1950°F ( 1010/1066°C ), soak,

quench in warm oil or cool in air, do not overheat, when overheated, full hardness can not be obtained.

Tempering

Hardness of approximately rockwell C 56/57 will be obtained on this steel, to remove peak stresses

and yet retain max. hardness temper at least one hour 300/350°F ( 148/176°F ).

Forms available
