Weather resistant steel SMA490AP,SMA490BP and SMA490CP under steel standard JIS G3114."Weathering" means that due to their chemical compositions, these steels exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather.Weathering steel plate SMA490AP,SMA490BP and SMA490CP all owned the higher yield strength which is above 365 Mpa for the steel plates thickness equal or below 16mm,and tensile strength shall be within 490Mpa to 610Mpa.
The main difference between these three steel grades SMA490AP,SMA490BP and SMA490CP is impacting test values,for weather resistant steel plate SMA490AP,no need to do low temperature impacting test according to standard,for weather resistant steel plate SMA490BP,it shall be done imapcting test under 0 centigree with minimum charpy absorbed energy 27J.For weather resistance steel plate SMA490CP,it shall be done low termpature impacting test with minimum energy 47J under zero centigree.Welcome our regular and new customers inqiury YUSHENG STEEL about these weathering steel plates SMA490AP SMA490BP and SMA490CP.
