Heat Treatment :

Annealing:
Annealing temperature:860-880℃, keep this temperature by 2-4 hours, then cooling to 600℃ in the speed of less than 30℃/h.
if after cold drawn process, suggest and stress relieving annealing process Under the temperature of 600-700℃, keep this temperature
by 2 houres.
Quenching & Tempering (saltbath)

Quenching:
Pre-heating in two steps:
Heating temperature under: 400-500℃ and 850-900℃
Austenitizing temperature: 1180-1220℃
Heating coefficient 10-15sec/mm, quenching under 580-620℃, then cooling to room temperature.

Tempering:
Tempering temperature under: 540-560℃, tempering 3 times, eachtime 1 hour, then cooling to room temperature.
