P20 Tool Steel bar Feature
A. Good heat-resistance and fatigue-resistance
B. Good integral mechanical performance under high temperature
C. Good hardness uniformity and polishing property,good machining properties
D. Pre-hardened to HRC30-36, 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
P20 Tool Steel bar Applications
1. Main components of overloading mold
2. TV cabinets,drum mold of washing machine,etc.
3. Plastic molds for injection compressing and injection molding
4. Often used in the manufacture of television cabinet, washing machine, refrigerator inner shell, buckets, etc
A high degree of micro-purity and excellent homogeneous structure, excellent polishing and photolithography.
After heat treatment, processing and polishing performance is good, can be nitriding treatment, suitable for chrome plating and other surface treatment, material hardness (to 400mm thick), good toughness, good machinability.
