DIN 1.2738 Steel Supplier in India | Premium Plastic Mould Steel from Jupiter Steels
Introduction to DIN 1.2738 Steel
DIN 1.2738 is a premium, pre-hardened plastic mould steel widely used for medium and large-sized moulds. It is a workhorse in the moulding industry, valued for its superior toughness, high polishability, and excellent machinability. This steel is typically supplied in a pre-hardened and tempered condition, which eliminates the need for further heat treatment and greatly simplifies the mould manufacturing process. At Jupiter Steels, based in Delhi, we are a leading stockist and supplier of DIN 1.2738 steel, providing certified material to customers across India, including industrial hubs in Haryana, Manesar, and beyond.
Chemical Composition of DIN 1.2738 Steel
The outstanding properties of 1.2738 steel are due to its specific chemical composition. The key alloying elements and their typical weight percentages are:
- Carbon (C): 0.35 – 0.45%
- Chromium (Cr): 1.80 – 2.10%
- Manganese (Mn): 1.30 – 1.60%
- Molybdenum (Mo): 0.15 – 0.25%
- Nickel (Ni): 0.90 – 1.20%
Functioning and Reasoning of Chemical Elements
- Nickel (Ni): Nickel is a key element in 1.2738 steel. It is the primary reason for the steel’s enhanced hardenability and superior toughness, which is particularly important for large mould blocks. Nickel also improves the steel’s response to polishing, helping to achieve a high mirror finish.
- Chromium (Cr): The chromium content provides the steel with hardenability and enhances its resistance to wear. It also contributes to the steel’s corrosion resistance.
- Manganese (Mn): Manganese increases the steel’s strength and toughness. It also plays a vital role in ensuring a uniform hardness throughout the material after heat treatment.
Hardness, Properties, and Applications of 1.2738
Hardness
DIN 1.2738 steel is typically supplied in a pre-hardened state, with a hardness ranging from 30-34 HRC. This pre-hardened condition allows for direct machining, saving time and preventing the risk of distortion.
Properties
- High Polishability: This is a standout property, allowing for a superior mirror finish, which is crucial for producing high-quality plastic parts.
- Excellent Machinability: In its pre-hardened state, it can be easily machined into complex shapes, making it a favorite among mould manufacturers.
- Good Weldability: It has good weldability, making it easy to repair or modify moulds, with minimal changes to the hardness in the weld area.
- High Toughness: The addition of Nickel gives this steel high toughness, allowing it to withstand the thermal and mechanical stresses of the injection moulding process.
Applications
1.2738 steel is specifically engineered for plastic moulding and finds a wide range of uses, particularly for medium and large mould blocks. Key applications include:
- Plastic Injection Moulds for consumer goods, automotive parts, and electronic casings.
- Mould Holders and Die Casting Dies for zinc alloys.
- Compression Moulds and Rubber Moulding Dies.
- Mould Frames for injection molding.

DIN 1.2738 Steel FAQ Section
Q1: What is DIN 1.2738 steel used for? A: DIN 1.2738 is primarily used for plastic injection moulds, especially for medium and large-sized components in the automotive and consumer goods industries.
Q2: Is DIN 1.2738 a stainless steel? A: No, DIN 1.2738 is not a stainless steel. While its chromium content provides some resistance to corrosion, it is not corrosion-proof and should be protected from harsh environments.
Q3: Can 1.2738 be used for hot work applications? A: No, DIN 1.2738 is a plastic mould steel designed for processes that do not involve the extremely high temperatures of hot work.
