1.2311 Steel Plate 360 x 160, AISI P20 Steel, 3Cr2Mo Plastic Tool Steel, Suppliers.

DIN 1.2311 steel plates offer a combination of strength, toughness, and wear resistance, making them ideal for mold and tooling applications.

Here’s a summary of its key properties and heat treatment recommendations:

1.2311 steel is a low-alloy tool steel known for its good toughness and wear resistance.

It is commonly used in applications requiring high strength and durability, such as in the manufacturing of plastic molds, die-casting dies, and other tooling components.

The steel is often used in a pre-hardened state, which simplifies the machining process and reduces the need for additional heat treatment.

1.2311 Steel Plate, AISI P20 Steel and 3Cr2Mo Plastic Tool Steel, Suppliers Key Properties:-

– Good toughness:- Suitable for applications where impact resistance is important.

– Wear resistance: Provides durability in high-stress environments.

– Machinability: Can be machined relatively easily in its pre-hardened state.

– Hardness: Typically supplied with a hardness of around 30-34 HRC (Rockwell C scale).

 Applications:-

Plastic molds:- Used for injection molds and other plastic processing tools.

Die-casting dies:- Suitable for aluminum and zinc die-casting applications.

Tooling components:- Used in various tooling applications where toughness and wear resistance are required.

Chemical Composition (typical):-

Carbon (C): 0.35-0.45%

Silicon (Si): 0.10-0.40%

Manganese (Mn): 1.30-1.60%

Chromium (Cr): 1.80-2.10%

Molybdenum (Mo): 0.15-0.25%

Vanadium (V): 0.05-0.15%

Heat Treatment:-

Pre-hardened:- Typically supplied in a pre-hardened condition to facilitate machining.

Hardening:- Can be further hardened by heat treatment if required, involving heating to around 840-860°C followed by quenching and tempering.

Machining and Fabrication:-

Machining:- Best performed in the pre-hardened state.

Welding:- Possible but requires preheating and post-weld heat treatment to avoid cracking.

1.2311 steel is a versatile material that balances toughness and wear resistance, making it suitable for a wide range of tooling applications.
