Purohit Steel is a leading P20 Plastic Mould Steel exporter and supplier in India. "P20" is the internationally recognised trade name for a family of pre-hardened alloy mould steels — this page explains what P20 steel actually is, why buyers search for it, how to evaluate a P20 supplier, and where to find the full technical datasheet for the specific P20 grade we stock.

If you already know you need chemical composition, mechanical property tables and heat treatment data, go straight to our Grade 1.2311 (P20) technical page — that is Purohit Steel's DIN-standardised P20 grade, with a full datasheet, comparison tables and downloadable PDF. This page instead covers the broader picture: what P20 means as a category, and how to buy it correctly.

What is P20 Steel?

"P20" is an AISI/SAE trade designation (from ASTM A681) for a category of pre-hardened, low-alloy chromium-manganese-molybdenum tool steel developed specifically for plastic mould and die-casting tooling. Rather than one exact chemistry, "P20" is best understood as a family of closely related grades that different steel standards define slightly differently — the German DIN equivalent is 1.2311 (40CrMnMo7), and a nickel-enhanced variant used for larger tooling is known as P20+Ni or DIN 1.2738.

What makes P20 steel distinctive, and why it became the default choice for plastic mould bases worldwide, is that it is supplied pre-hardened (quenched and tempered, typically 29-33HRC) straight from the mill. Mould makers can machine cavities and cores directly without needing a separate hardening cycle, which shortens lead times and avoids the dimensional distortion that comes with post-machining heat treatment.

P20 steel is prized for its balance of machinability, toughness and polishability — good enough surface finish for most commercial plastic parts, tough enough to survive millions of injection cycles, and easy enough to machine that tooling costs stay reasonable.

How to Choose a P20 Steel Supplier

Not all "P20 steel" sold in the market is equal. Because P20 is a trade category rather than one tightly policed specification, sourcing quality varies significantly between suppliers. Here is what to check before you commit to a supplier:

  • Verified mill test certificates: Ask for EN 10204 2.2 or 3.1 certificates confirming actual chemical composition and hardness for the batch you are buying, not generic literature.
  • Hardness consistency through the block: A surface hardness reading alone does not guarantee uniform hardness through a thick mould base — ask how the supplier verifies core hardness, especially for large blocks.
  • Genuine ready stock: Confirm whether the sizes you need are physically in stock, versus a supplier who imports on order and adds weeks to your lead time.
  • In-house value-added processing: Suppliers who can bandsaw-cut, machine, grind, drill and EDM in-house save you a separate vendor step and reduce handling risk.
  • Technical support for grade selection: A supplier who can advise whether you actually need P20+Ni instead of base P20 (or a corrosion-resistant grade instead of either) is more valuable than one who just quotes what you ask for.
  • Export documentation and packaging: If you are sourcing from India for export, confirm the supplier can provide proper export packing and shipping documentation.

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 steel" commonly refers to two related grades that Purohit Steel stocks. 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.

GradeDIN DesignationBest ForFull Datasheet
P20 (base grade)1.2311 (40CrMnMo7)Small to medium moulds, general mould-base toolingView Grade 1.2311 →
P20+Ni (nickel-added)1.2738 (40CrMnNiMo8-6-4)Large mould blocks needing deep, uniform hardenabilityView Grade 1.2738 →

If your application involves corrosive plastics, humidity, or water-cooled cavities, also consider our corrosion-resistant grades: 1.2085 and 1.2083 ESR.

P20 Steel Across Industries

P20 steel's combination of machinability, toughness and reasonable polishability has made it the default mould-base material across a very wide range of manufacturing sectors:

Automotive

Used for dashboards, bumpers, interior trim and other precision plastic components where dimensional stability and surface finish matter over long production runs.

Packaging

Used for containers, caps, closures and household product moulds that need consistent cavity dimensions across high injection volumes.

Electrical & Electronics

Used for enclosures, switchgear housings, connectors and other precision plastic components in electrical manufacturing.

Consumer Goods

Used for appliance housings, furniture components and general consumer product tooling where cost-effective, reliable mould life is the priority.

General Engineering & Die-Casting

Used for low-pressure die-casting dies, extrusion dies and tooling plates beyond pure plastic injection moulding.

Frequently Asked Questions

P20 is a widely used family of pre-hardened chromium-manganese-molybdenum alloy tool steel used to build plastic injection moulds, blow moulds and general tooling. It is internationally standardised in Germany as DIN 1.2311 (40CrMnMo7).

P20 is the AISI/SAE trade name for the family; Purohit Steel's specific P20 grade is DIN 1.2311 (40CrMnMo7), which carries a full technical datasheet with verified chemical composition and mechanical properties. View the datasheet →

P20+Ni (DIN 1.2738) is a nickel-alloyed version of P20 offering deeper, more uniform through-hardenability, making it better suited to large mould blocks, while base P20 (1.2311) is more economical for small to medium moulds. See our P20+Ni page for more.

Look for verified mill test certificates, consistent hardness through the block (not just surface readings), genuine ready stock rather than import-on-order, in-house machining capability, and technical support for grade selection. See the full checklist above.
