NM500 NM550 Hot Rolled Wear Resistant Steel Plate
NM500 is a high-strength abrasion resistant steel plate, naming: N is "wear-resistant" in the "resistant" in the first letter of the alphabet, M is "wear-resistant" in the "grinding" in the first letter of the alphabet.500 is the Brinell hardness value of HB value. (500 is the Brinell hardness value of HB. (500 hardness value is broad, domestic NM500 hardness value is around 500.) It has a high resistance to wear, Brinell hardness value of 500 (HBW) is mainly in the need to wear-resistant occasions or parts of the protection, so that the equipment life is longer, reduce maintenance brought about by overhauling and downtime, and accordingly reduce the investment of funds.
NM550's high wear-resistant high strength and high toughness performance in the manufacture of machinery and equipment to effectively avoid mechanical equipment in and friction in the place of damage or deformation, can directly improve the service life of machinery.
