Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of hardness of SMA490CW etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in hardness of SMA490CW etc. steel is strictly controlled.
Main business: carbon steel plate cutting, round steel cutting, stainless steel cutting, round pipe cutting, hardness of SMA490CW, steel structure welding. It can also cut various machine tool side plates, special-shaped parts, flanges, bearing seats, bearing supporting bases, embedded parts, counterweights, rolling stands, cutting squares, cutting circles, etc. according to customer drawings. BBNsteel company has good business channels with major steel mills, and undertakes all kinds of steel plate processing services.
BBN steel hardness of SMA490CW 15mm to 35mm thick size: 15*2120*5620, 17.5*2320*13000, 18*2450*5500, 20*3000*5000, 19*2580*4700, 19.5*1970*4000, 20*1600*7740, 20.5*2370*7000, 21*2650*7500, 21*1920*8220, 22*1380*7650, 22*1800*8000, 22.5*1680*8450, 23*3000*11980, 23.5*2080*8100, 24*1560*6200, 25.5*2330*8300, 26*3010*8100, 26.5*2000*7000, 27*2550*6800, 27.5*2700*5500, 29*2550*9000, 29*2870*12000, 32*3300*6000, 33*2340*6700, 34*2120*6100, 35*1300*4100.
AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, hardness of SMA490CW. The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.
