What is Grade 1.2311 Steel?
Grade 1.2311 steel is a pre-hardened Plastic Mould Steell widely used in the manufacturing of injection moulds and plastic tooling applications. It is also known as P20+Ni steel and is one of the most popular mould steels used in the global tooling industry.
This steel grade is supplied in a pre-hardened condition, usually around 28–32 HRC, which eliminates the need for further heat treatment. This makes it highly cost-effective for mould manufacturers and reduces production time significantly.
1.2311 steel is known for its excellent machinability, uniform hardness, good polishability, and dimensional stability. It is widely used in plastic injection moulds where smooth surface finish and long service life are required.
Mechanical Properties of 1.2311 Steel
Grade 1.2311 offers a balanced combination of strength and machinability, making it ideal for mould manufacturing industries.
- Hardness: 28–32 HRC (pre-hardened condition)
- Excellent machinability for CNC and VMC machining
- Good tensile strength and wear resistance
- High polishability for plastic mould finishing
- Uniform hardness across the cross-section
- Good dimensional stability during machining
Due to these properties, 1.2311 steel is widely used in high-performance injection mould applications where precision is critical.
Applications of Grade 1.2311 Steel
1.2311 steel is widely used in plastic mould manufacturing industries across India and globally. Its versatility makes it suitable for a wide range of industrial applications.
- Plastic injection moulds
- Automotive plastic components
- Packaging industry moulds
- Household product moulds
- Industrial engineering moulds
- Die blocks and mould frames
- Plastic containers and consumer goods
In the automotive sector, 1.2311 steel is used for manufacturing dashboards, interior parts, bumpers, and precision plastic components due to its excellent surface finish and stability.
