SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate, A514 grade B alloy steel plate with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.
NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product A514 grade B alloy steel plate is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of A514 grade B alloy steel plate, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
