P20 + Ni Steel Supplier in India | Premium Plastic Mould Steel from Jupiter Steels
Introduction to P20 + Ni Steel
P20 + Ni steel 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 P20 + Ni steel, providing certified material to customers across India, including industrial hubs in Haryana, Manesar, and beyond.
Chemical Composition of P20 + Ni Steel
The outstanding properties of P20 + Ni 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 P20 + Ni 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 P20 + Ni
Hardness
P20 + Ni 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
P20 + Ni 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.

P20 + Ni Steel FAQ Section
Q1: What is P20 + Ni steel used for?
A: P20 + Ni is primarily used for plastic injection moulds, especially for medium and large-sized components in the automotive and consumer goods industries.
Q2: Is P20 + Ni a stainless steel?
A: No, P20 + Ni 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 P20 + Ni be used for hot work applications?
A: No, P20 + Ni is a plastic mould steel designed for processes that do not involve the extremely high temperatures of hot work.
