S355NL Steel Plate belongs to standard of EN10025-3. Full Name: Normalizing/Normalizing rolled weldable fine grain structure steel plates. This standard together with EN10025-1 replaces EN 10113-1:1993 hot rolled steel products with weldable [TJC STEEL]fine grain structure -- Part 1: General Conditions and EN 10113-2: Hot-rolled weldable fine grain structural steel products - Part 2: Conditions for normalizing/normalizing rolled steel. When the temperature is not less than -20°C, the minimum impact energy is specified, denoted by N. When the temperature is not less than -50°C, the minimum impact energy is specified, denoted by NL.
Name of Steels:
S: for structural steel, N: state, capital L: [TJC STEEL]specifies the level of minimum impact energy at a temperature not lower than -50°C.
Strength: Tensile strength: RM630-450mpa. Yield strength: 355-275mpa, elongation after fracture 21-22%.
