Purohit Steel is a leading P20+Ni Plastic Mould Steel exporter and supplier in India. "P20+Ni" (also called P20 Modified) is the trade name for a nickel-alloyed upgrade of standard P20 steel, purpose-built for large mould blocks. This page explains what P20+Ni actually is, when it makes sense over base P20, how to evaluate a supplier, and where to find the full technical datasheet for the specific P20+Ni grade we stock.

If you already know you need chemical composition, mechanical property tables and heat treatment data, go straight to our Grade 1.2738 (P20+Ni) technical page — that is Purohit Steel's DIN-standardised P20+Ni grade, with a full datasheet, comparison tables and downloadable PDF. This page instead covers the broader picture: what P20+Ni means as a category, and how to buy it correctly.

What is P20+Ni Steel?

"P20+Ni" (also marketed as P20 Modified) is not a separately standardised AISI/SAE code but an industry-wide trade name for a family of pre-hardened, chromium-manganese-molybdenum mould steel with roughly 0.9-1.2% nickel added. The German DIN equivalent that most mills and buyers reference is 1.2738 (40CrMnNiMo8-6-4).

The nickel addition is the whole point of this grade: it improves through-hardenability, meaning the core of a thick mould block hardens almost as evenly as its surface during quenching. Plain P20 (1.2311) can show a meaningful hardness drop-off toward the centre of large sections; P20+Ni largely solves that problem, which is why it became the default upgrade for large plastic injection mould bases.

Like base P20, P20+Ni is supplied pre-hardened (typically 32-37 HRC) directly from the mill, so mould makers can machine cavities and cores without a separate hardening cycle — but with the added benefit of more predictable, uniform mechanical properties across a large block.

How to Choose a P20+Ni Steel Supplier

Because P20+Ni is typically ordered for larger, more expensive mould blocks, the cost of getting the supplier wrong is higher than with smaller P20 orders. Here is what to verify before committing:

  • Verified mill test certificates: Ask for EN 10204 2.2 or 3.1 certificates confirming actual chemical composition, including nickel content, and hardness for the specific batch.
  • Evidence of through-hardness on large sections: The whole reason to pay more for P20+Ni is uniform core hardness — ask how the supplier verifies this on the block sizes you need.
  • Genuine ready stock in large sizes: Confirm the supplier physically stocks large blocks rather than placing a special import order once you commit, which can add significant lead time on big tooling projects.
  • In-house heavy machining capability: Bandsaw cutting, machining, grinding, drilling, gun drilling, EDM and wire-cut capable of handling large, heavy blocks in-house reduces handling risk and vendor coordination.
  • Technical support for grade selection: A supplier who can confirm whether your mould actually needs P20+Ni, or whether base P20 or a corrosion-resistant grade would serve better, is more valuable than one who simply quotes what is asked.
  • Export documentation and packaging: For export orders, confirm proper packing and shipping documentation for heavy sections.

Purohit Steel, an ISO-certified company established in 1965 and an authorized stockist of NLMK Verona and SeAH CSS, is built around these exact requirements — see why buyers choose us below.

The P20 Family at a Glance

"P20+Ni" is one of two related grades that Purohit Steel stocks within the P20 family. Full technical data for each is published on its own dedicated page — this table is only a quick-reference summary, not a substitute for the datasheets.

P20+Ni Steel Across Industries

P20+Ni's uniform through-hardness makes it the preferred material wherever a plastic mould base is large, thick-sectioned, or produced in very high volumes:

Automotive

Used for large bumper, dashboard and structural interior/exterior trim moulds where consistent core hardness across a big cavity is essential for long tool life.

Packaging & Consumer Goods

Used for large container, crate and appliance housing moulds that need predictable dimensional stability over very high production volumes.

Industrial & Die-Casting Tooling

Used for large mould base plates, holder blocks and low-pressure die-casting dies where section thickness would otherwise cause uneven hardness in base P20.

High-Volume Injection Moulding

Used wherever mould life and dimensional consistency across millions of cycles justify the additional cost of the nickel-alloyed grade over base P20.

Frequently Asked Questions

P20+Ni is a nickel-alloyed variant of the P20 family of pre-hardened mould steel, offering deeper and more uniform through-hardenability than base P20. It is standardised in Germany as DIN 1.2738 (40CrMnNiMo8-6-4).

P20+Ni (or P20 Modified) is the common trade name; Purohit Steel's specific P20+Ni grade is DIN 1.2738, which carries a full technical datasheet with verified chemical composition and mechanical properties. View the datasheet →

Choose P20+Ni when your mould block is large or thick-sectioned and you need consistent hardness through the core, not just at the surface. For smaller moulds with moderate section thickness, base P20 (1.2311) is usually more economical. See our P20 page for more.

Look for verified mill test certificates, evidence of consistent through-hardness on large sections, genuine ready stock, in-house machining capability, and technical support for grade selection. See the full checklist above.
