ASTM Corten A steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
EN 10155 S355J2WP is a structural weathering steel which is also referred to as atmospheric corrosion resistant steel.
The steel grade Corten B is according to ASTM standard which with the yield strength of 355MPa and 345MPa which is based on the different thickness.
Q355NH steel chemical composition can increase resistance to atmospheric corrosion compared to other steels.
SPA-H steel chemical composition can increase resistance to atmospheric corrosion compared to other steels.
A242 Type 1 steel chemical composition can increase resistance to atmospheric corrosion compared to other steels.
