Product Description

1.2738 Plastic Mould Steel Sheet and Plate

What is 1.2738 P20+Ni Steel ?
1.2738 P20+Ni Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The special purpose mold steel 1.2738 P20+Ni steel plate is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. 1.2738 P20+Ni mold steel plate material is typically sold in the pre-hardened condition.

1.2738 P20 Ni round bar, flat bar, plate and block.As an alloy tool steel grade 1.2738 P20 Ni is commonly supplied in the hardened and tempered condition with a supply high hardness.This steel gives an excellent polished finish and is one of the most widely accepted specifications for machine cut plastic moulds and zinc die casting dies. This grade gives excellent wear resistance but if maximum surface hardness is required for compression moulding plastic dies or similar tools, the steel can be case hardened or nitrided.
