Introduction

In the world of plastic mould making, choosing the right tool steel is important for performance, cost, and the quality of the final product. Two commonly used materials are P20 Tool Steel and P20S Tool Steel. Both are pre-hardened steels used for making moulds, but they have different qualities in terms of how easy they are to machine, how well they can be polished, and which applications they are best suited for.

What is P20 Tool Steel?

P20 Tool Steel is a flexible, pre-hardened mould steel that is known for its:

- Hardness of 28 to 32 HRC when first delivered.

- Strong toughness and durability.

- Good machinability for standard mould making.

- Suitable for use in plastic injection moulds, extrusion dies, and die casting tools.
