nm300 is a high-density wear-resistant steel material with high wear resistance and a Brinell hardness value of 300HBW. It mainly provides protection in occasions or parts that require wear resistance, extend the life of equipment, reduces maintenance and downtime caused by maintenance, and accordingly reduces capital investment.
NM300 wear resistant steel plate has excellent hardness, usually between HBW270-330.Due to the high hardness, NM300 steel plate can effectively resist wear, scratches and impacts, making it perform well in harsh working environments.
