1.2311 P20 Prehardening Wear Resistance Plastic Mold Steel Flat and Round Bar
Prehardening Wear Resistance mechanical behavior AISI P20 Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The special purpose Prehardening mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. P20 mold steel plate material is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW. And wth good cutting mechanical property.
1, Features:
a, Good hardness uniformity and polishing property,good machining
properties.
b, Good integral machanical performance under high temperature.
c, Good heat-resistance and fatigue-resistance,high mechanical
behavior,cutting mechanical property.
d, Pre-hardened to HRC28-32, can be directly used for mould
processing, shorten the construction period.
e, High putity and homogeneous structure of China's biggest ESR
production base for its strict requirement in the whole process of
exploitation, smelting, vacuum degassing, ESR, forging, annealing,
inspection.
