High-strength. Long life. Indian pricing.
HIND HARD NM 400 Plates are built for one thing — to last longer under wear. With a hardness of ~400 BHN and outstanding structural performance, these plates are perfect for mining chutes, buckets, concrete mixers, material hoppers, and all high-abrasion industries. Whether you’re a fabricator, OEM, or EPC contractor, our cut-to-size NM400 plates are ready with test certificates, fast delivery, and custom profiling.
NM 400 Plate is a wear-resistant steel plate manufactured under Chinese standard GB/T 24186-2009 with a nominal hardness of 400 Brinell. “NM” stands for “耐磨” (Nai Mo), meaning wear-resistant in Chinese.
It combines:
This makes it ideal for industries where equipment faces continuous material flow — like mining, power, quarrying, cement, and construction.
NM 400 is used in high-friction, high-impact environments such as:
