What is Solution-treated Mn13 steel plate
Solution-treated Mn13 steel plate is a high-manganese wear-resistant steel plate produced through a high-temperature solution heat treatment process (typically 1000–1100°C followed by water quenching).
This process dissolves carbides back into the austenite matrix, forming a stable single-phase austenitic structure with outstanding toughness and impact resistance. Compared with ordinary carbon steel, Mn13 steel can deliver 3–5 times higher service life under severe impact and abrasive wear conditions, depending on the working environment.
After solution treatment, Mn13 steel plate exhibits exceptional work-hardening capability. Its initial hardness is relatively low, typically around 180–220 HB, but under strong impact and continuous abrasion, the surface hardness can rapidly increase to 450–550 HB, and in extreme working conditions may even exceed this range locally.
This strong work-hardening response allows the material to continuously strengthen during service while the core remains tough and ductile. Unlike conventional steels that wear down gradually, Mn13 becomes harder as it is used, improving its resistance to impact and sliding wear.
Thanks to this unique "self-hardening" behavior, solution-treated Mn13 steel plate is widely used in mining machinery, crusher liners, hoppers, chutes, excavator buckets, and other high-impact wear environments.
In practical applications, it can reduce maintenance and replacement costs by approximately 40–60% compared with traditional carbon steel or low-alloy wear-resistant steel, making it a highly cost-effective solution for heavy-duty industries.
GNEE has over 18 years of manufacturing and exporting experience in wear-resistant steel products and has supplied solution-treated Mn13 steel plates to mining operators, cement plants, steel mills, and heavy equipment manufacturers in more than 80 countries worldwide.
Our Mn13 steel plates are widely used in high-impact and high-abrasion applications such as crusher liners, hoppers, chutes, and excavator wear parts. We support both large-scale engineering projects and small trial orders, with a minimum order quantity (MOQ) as low as one piece.

What is difference between the A36 and Mn13 steel plate?
Mn13 steel plate has about 3–5 times longer service life than A36 carbon steel in high-impact wear conditions, because Mn13 work-hardens to 450–550 HB, while A36 remains at about 120–160 HB with no work-hardening ability.
What is difference between the A36 and NM400 steel plate?
Mn13 steel plate is better for high-impact and severe shock wear, and can reach 450–550 HB after work hardening, while NM400 has a constant hardness of about 360–420 HB, so Mn13 can last about 1.5–3 times longer than NM400 in strong impact conditions, NM400 performs more stably in low-impact abrasive wear.
