NM550 High Strength Abrasion Resistant Steel NM550 Wear-Resistant Plate

NM550 Abrasion Resistant Steel Plate Description

NM550 Wear-Resistant Steel Plate implements the GB/T24186 standard, NM means wear-resistant, 550 is the Brinell hardness value (HBW), and 550 is also the wear-resistant grade. It is suitable for wear-resistant structural parts of construction machinery such as engineering, mining, construction, agriculture, cement production, ports, electric power, and metallurgy that require high strength and high wear resistance under particularly harsh working conditions. Such as bulldozers, loaders, excavators, dump trucks and various mining machinery, grab buckets, stackers and reclaimers, feeding bending structures, etc.

GB/T24186 NM550 Abrasion Resistant steel is a modulated high wear-resistant steel plate. NM550 steel is not only a high-strength wear-resistant steel plate but also has certain toughness and fatigue resistance. It is mainly used in mining machinery, coal mine machinery and equipment, environmental protection equipment, sand and gravel machinery, etc. The high wear resistance, high strength and high toughness of NM550 can effectively avoid damage or deformation of mechanical equipment in places with high friction when manufacturing mechanical equipment, and can directly improve the service life of machinery. The delivery state of the wear plate is quenched, quenched + tempered, TMCP + tempered, tempered or hot rolled.

NM550 Abrasion Resistant plate also has very high wear resistance, corrosion resistance, impact resistance, fatigue resistance, welding ease of processing and cold forming performance. NM500 steel adopts electric furnace steelmaking, made of scrap iron, and the steel is pure , The steel plate is a flat steel material that is poured with molten steel and pressed after cooling. It is flat, rectangular, and can be rolled directly or cut from a wide steel strip. Steel plates are classified according to thickness, thin steel plates < 8 mm (thinnest 0.2 mm), medium-thick steel plates 8-60 mm, and extra-thick steel plates 60-120 mm.
