What are the advantages and disadvantages of laser cutting of nm500 grade material

BBN steel NM500 grade material 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.

According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw NM500 grade material steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the NM500 grade material market due to the impact of the closure of local steel mills in Italy.

Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the NM500 grade material alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the NM500 grade material wear-resistant property to meet the requirements of specific working conditions.

Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, NM500 grade material, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.
