Description
P20 mold steel a pre-hardened grade steel. An amazing quality Steel for plastic moulds.
P20 mold steel intro.
P20 mould steel is a versatile, low-alloy tool steel that is characterized by good sturdiness at slight strength degrees.
They usually use the steel for plastic injection mold cavities and tooling and for die casting dies for zinc.
They typically buy p20 within the pre-hardened condition at a hardness of approximately 299 hbw.
ANNEALING.
Heat at a rate not exceeding 401°F per hour to 1450°F, and hold at temperature for 1 hour per inch (25.3mm) of maximum thickness; 2 hours minimum.
Then cool slowly with the furnace at a rate not exceeding 50ºF per hour to 1150ºF. Continue cooling to ambient temperature in the furnace or in the air.
