Application and heat treatment of nm300 steel equivalent grades

The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, nm300 steel equivalent grades tube.

According to the hardness from HB400 to 600, wear-resistant plates can be divided into NM400, NM450, NM500, NM550, NM600 and so on. Because of its toughness, the wear plate can accept impact, sensation, bump, scratch and prick day after day. With its good processing performance, wear-resistant plate, nm300 steel equivalent grades can be bent, formed and welded, and can prevent the occurrence and propagation of cracks, which is also the reason why wear-resistant plate can be used as structural steel.

ArcelorMittal said it was taking measures to cut its North American nm300 steel equivalent grades steel production in response to the weakening demand for downstream steel after the outbreak of covid-19, foreign media reported. It is reported that ArcelorMittal's plant in the port of Indiana is ready to shut down the No. 4 blast furnace.

BBN steel nm300 steel equivalent grades 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.
