1.2311 Steel Supplier in India | High-Quality Pre-Hardened Plastic Mould Steel

Introduction to 1.2311 Steel

1.2311 steel is a widely used, pre-hardened chromium-molybdenum alloy steel specifically designed for the plastic mould industry. It is highly valued for its excellent machinability, polishability, and its ability to maintain uniform hardness throughout large cross-sections. Since it is supplied in a ready-to-use condition, it saves significant time and cost by eliminating the need for complex heat treatment by the mould maker. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of 1.2311 steel, providing certified material to customers throughout India, including key industrial regions like Manesar, Haryana, and beyond.

Chemical Composition of 1.2311 Steel

The reliable performance of 1.2311 steel is a direct result of its carefully controlled chemical composition. The key alloying elements and their typical weight percentages are:

• Carbon (C): 0.35 – 0.45%
• Manganese (Mn): 1.30 – 1.60%
• Chromium (Cr): 1.80 – 2.10%
• Molybdenum (Mo): 0.15 – 0.25%
• Silicon (Si): 0.20 – 0.50%

Functioning and Reasoning of Chemical Elements

• Chromium (Cr) & Molybdenum (Mo): This combination provides high hardenability and contributes to the excellent mechanical properties. Molybdenum also prevents temper brittleness, ensuring the steel retains its properties after tempering.
• Manganese (Mn): The relatively high manganese content enhances the steel’s hardenability, allowing it to achieve deep and uniform hardening in its pre-hardened state.
• Carbon (C): The medium carbon content provides the necessary strength and hardness for its application as a mould steel.

Hardness, Properties, and Applications of 1.2311

Hardness

1.2311 steel is typically supplied in a pre-hardened and tempered condition with a ready-to-use hardness in the range of 28-32 HRC (approximately 277 – 311 HB).

Properties

• Good Machinability: In its pre-hardened state, it can be easily machined, reducing tool wear and manufacturing time.
• Excellent Polishability: The clean microstructure allows for a superior mirror finish, which is critical for producing highly aesthetic plastic parts.
• Uniform Hardness: It maintains consistent through-hardness, even in large blocks.
• High Toughness: It offers a good balance of hardness and toughness, preventing breakage under normal operating conditions.

Applications

1.2311 steel is a preferred grade used for a wide range of medium to large plastic mould applications. Key applications include:

• Mould Inserts and Cavities for injection moulding
• Mould Plates and Frames
• Compression Moulding Dies
• Tool Holders
