NM550 High strength Wear-Resistant Steel

NM550 is an average hardness of wear-resistant steel 550HBW and is used in high wear applications. It is intended for the use of high manganese steel or Brinell hardness of 500 users and manufacturers of wear resistant steel.

When upgrading from HARDOX500 plate to the products in the Brinell hardness of 50 units, extend plate life without loss of toughness of steel, which can withstand heavy wear. It is suitable for work wear in strong environments, such as high strength ore and corrosive materials.
