When Impact Is Constant and Failure Is Not an Option — Choose ASTM A128 Plates
If you’re in the business of mining, cement, quarrying, or crushing, you already know that regular steel doesn’t last long in impact zones. That’s why industries worldwide rely on ASTM A128 Manganese Steel Plates — the internationally recognized standard for Hadfield steel, trusted for over 100 years.
At Hindustan Steel Corporation, we stock and supply ASTM A128 Grade B2 manganese plates, engineered to outperform traditional AR steels in impact-heavy, gouge-prone, and abrasive applications.
ASTM A128 is the American standard specification for austenitic manganese steel castings and rolled plates. It ensures strict control of manganese content (11–14%), impact strength, ductility, and work-hardening behavior.
Often compared to X120Mn12 and MN13, ASTM A128 Grade B2 is a benchmark for manufacturing:

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:
