NM400 steel is a high-strength wear-resistant steel plate. A573 grade 70 carbon steel plate, NM400 steel has quite high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; NM400 steel plate can significantly improve the wear resistance of mechanical related parts; therefore, it can increase the service life of machinery and reduce production costs. NM400 wear-resistant steel plate is mainly used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
ASTM A537 class 1 boiler plate is pressure vessel steel. A573 grade 70 carbon steel plate, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.
20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for A573 grade 70 carbon steel plate steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A573 grade 70 carbon steel plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
