Upgraded Mold Performance
Nickel-Enhanced Plastic Mould Steel P20+NI
P20+NI is an upgraded, pre-hardened plastic mould steel enhanced with Nickel to significantly improve through-hardness, toughness, and polishability. Providing a uniform hardness of 280-320 HB even in large sections, it is the professional choice for high-precision injection moulds. The Nickel addition ensures superior surface finish and better weldability for mold repairs, making it an essential grade for demanding automotive and domestic product tooling.
Key Features
