S355 S355N S355NL Steel Angle Channel
structural steel angle Products Description
S355 angle steel is mainly used in the production of engineering machinery, ships, bridges, high-rise buildings, boilers, pressure vessels, electric power, various types of vehicles, etc.
S355N is implemented in accordance with EN10025 standards. It is a European standard hot-rolled structural part, used in conjunction with S355JO, S355K2, S355J2 and other similar materials.
S355NL is a normalized steel (fine grain steel) suitable for EU 10025-3:2004. Its yield strength and tensile strength are equivalent to my country's Q345 low alloy steel. NL means that the impact absorbed energy test needs to be carried out in a low temperature environment of -50 degrees Celsius, and the impact value is not less than 27J.
