SM570 is Japan's standard JIS G 3106-1999 "Rolled steel for welded structure",SM570
low alloy steel plate is a typical low-alloy high-strength steel, the strength level is the highest in the JIS G 3106 standard, SM570 widely used in construction machinery, bridges , Containers, vehicles, ships, electrical equipment, and other structural parts, the steel in the requirements of high strength at the same time, also requires a high impact toughness of low temperature.
The yield strengthSM570 low alloy steel plate yield strength is 460MPa level. SM570 low alloy steel plate low alloy steel plate are often able to achieve higher strength in the hot-rolled or controlled rolling conditions owing to the strength grade steel of SM570 steel plate have a variety of alloying elements, including micro-alloying Elements, but the impact toughness fluctuations, performance is not stable, clearly, It is evident that the hot rolling process, especially the finish rolling temperature and cooling rate, have a significant impact on performance.
BBNsteel choose to delivery of SM570 low alloy steel plate according to normalized state, according to the standard, If necessary, SM570 steel plate can also be normal plus tempering delivery.We are professional steel of SM570 low alloy steel plate ,and we have one class service for SM570 low alloy steel plate.
