Europe’s Standard for Extreme Wear — X120Mn12 / 1.3401 Manganese Steel Plates
When you need a wear-resistant plate that doesn’t just last—but strengthens under impact, X120Mn12 is the European standard you can trust. Also known as DIN 1.3401, this high manganese steel is equivalent to Hadfield steel and is the top choice for mining, shot blasting, cement, rail, and heavy machinery where extreme wear and shock resistance are critical.
At Hindustan Steel Corporation, we supply certified X120Mn12 plates and DIN 1.3401 sheets to OEMs, EPC contractors, and heavy equipment fabricators across India and export markets.
DIN 1.3401 (X120Mn12) is a non-magnetic, work-hardening austenitic manganese steel containing 11–14% manganese. It is known for its:
This steel is used in crushing, mining, shot blasting, and rail crossing components where standard AR steels fail under high impact.

Our DIN 1.3401 plates are used in industries such as:
All parts can be cut-to-size, edge-prepped, or CNC profiled per your requirement.

A metro rail contractor replaced standard carbon steel with X120Mn12 wear plates for frog points and crossing blocks. The result:
We dispatch X120Mn12 and DIN 1.3401 manganese plates to:

Both are similar in composition, but X120Mn12 is preferred in Europe and India for its uniform work-hardening and consistent surface finish.
Yes. Like all Hadfield steels, it is fully non-magnetic.
Yes, using plasma or waterjet. Weld with special electrodes and controlled cooling.
If you need plates that harden under pressure, resist gouging, and last longer — DIN 1.3401 / X120Mn12 from Hindustan Steel Corporation is your best bet. Supplied with full certifications and precision fit.

High Manganese Steel Plates are engineered for high-impact environments. These plates are the top choice for industries like mining, crushing, cement, quarrying, power generation, shot blasting, and agriculture, where wear resistance is critical.
We offer a full range of grades and specifications such as ASTM A128, DIN 1.3401 / X120Mn12, and 12–14% Mn steel for crushers, plowshares, and structural applications.
At Hindustan Steel Corporation, our HIND MANGANESE plates are not just alternatives to international grades
Curious about how manganese steel behaves, whether it rusts, or how it compares with AR steel?
We are trusted exporters of high manganese steel plates to UAE, South Africa, Vietnam, Oman, and Southeast Asia, with custom cuts, seaworthy packaging, and all documentation included.
Our high manganese steel plates meet the strictest standards for abrasion resistance, impact toughness, and metallurgical reliability across industries.
Choosing between AR500, chromium carbide plates, and manganese steel? Want to know what makes Hadfield steel special, or how to cut and weld high manganese plates?
High manganese steel is unique among wear plates. It doesn’t just resist abrasion — it transforms under it. As it gets hit, it hardens. Here’s what technical buyers, engineers, and OEMs need to know:
To support engineering teams, procurement heads, and OEM partners, we provide a range of downloadable documents, buyer tools, and certification support below.
