P20 DIN 1.2311 Plastic Mould Steel in Gurugram – Versatile for Injection Molding

What is P20 DIN 1.2311 Plastic Mould Steel?

P20 DIN 1.2311 is a pre-hardened plastic mildew metallic broadly used within the tooling enterprise for production plastic injection molds and die casting additives. Known for its exceptional machinability and balanced power, DIN 1.2311 steel is furnished in a hardened and tempered condition, removing the need for extra warmth treatment.

What is P20 DIN 1.2311 Steel?

DIN 1.2311 (P20) is a pre-hardened plastic mildew metal recognized for its extraordinary machinability, toughness, and dimensional stability. It is broadly used for medium to big mildew applications.

Hardness: 28–34 HRC (pre-hardened)
Composition includes chromium and molybdenum for power and put on resistance
Equivalent grades: AISI P20, JIS SCM4

Key Features of P20 Mould Steel
Excellent machinability – reduces manufacturing time
Good polishability – perfect for terrific surface finish
