What Industries Use P20 Steel? Applications, Benefits & Uses
Introduction
P20 steel is one of the most widely used pre-hardened tool steels in the manufacturing industry. Known for its excellent machinability, good toughness, superior polishability, and long service life, P20 steel has become the preferred material for producing plastic moulds, dies, and precision tooling.
Because it is supplied in a pre-hardened condition (typically 28–32 HRC), P20 steel minimizes additional heat treatment, reducing production time and manufacturing costs. Its ability to withstand repeated production cycles while maintaining dimensional stability makes it suitable for a wide range of industrial applications.
In this article, we’ll explore the industries that rely on P20 steel and why it continues to be a top choice for tooling and mould manufacturing.
What is P20 Steel?
P20 steel is a low-alloy, pre-hardened mould steel specifically developed for plastic injection moulds and die applications. It offers an excellent combination of:
- High strength
- Good wear resistance
- Excellent machinability
- Uniform hardness
- Good toughness
- Superior polishability
- Long mould life
These properties make it ideal for manufacturing precision moulds used in high-volume production.
