Annealing:
Before the heat treatment processing is annealing temperature is
870 ~ 880 degrees, heat preservation of 2 ~ 3 hours, 800 degrees
and 800 a, 1270 from a 1280 - degree interrupted quenching, sizing
temperature for 580 a, 620, then 560 degrees to three tempering,
tempering heat preservation for 1 hour.
Forging:
High speed steel is easy to burn when heated, and it is easy to break the forging in this temperature range, and strictly control its heating temperature.
Quality Condition:
