Hot Rolled Alloy Steel Plate 1.2738 AISI P20+Ni 718H
Introduction:
2738 is one improved kind of pre- hardened mirror plastic die steel.With the alloy optimization and structure control key technology,
We can guarantee the steel die block has high hardness uniformity, excellent polishing property and machining property with large cross sections in China.
This steel can replace the imported new large cross sectional prehardened plastic die steel such as 1.2738/718HH/P20 modified, etc.
Applications:
Plastic molds for injection compressing and injection molding
TV cabinets, drum mold of washing machine, etc.
Features:
1.Good welding property of prehardened die blocks
2.Good polishing property(high hardness uniformity, hardness fluctuation ≤2hrc
3.Excellent working
4.Extra large cross sections:700mm*1300mm maximum and weighs 20MT for one piece
5.Application hardness:28-36HRC
6.CCT curve for reference
