EN standard low alloy S355J2 steel is S355 structural steel, whose properties is better than that of S235 and S275 steel in yield strength and tensile strength. Normally S355 structural steel has a lot of variations such as S355J0, S355JR, etc. based on impact strength at different temperatures, as steel become more brittle when temperature drops. If your structure need to withstand -20°C, it's better and safer to choose low alloy S355J2 steel.
Do you know what is EN standard low alloy S355J2 steel number? S355J2 steel number is 1.0577. S355J2 steel is also known as 1.0577 steel. EN standard low alloy S355J2 steel is welder-friendly, low carbon, high tensile strength structural steel. EN standard low alloy S355J2 steel can be readily welded to other weldable steel. For its low carbon equivalent, EN standard low alloy S355J2 steel possesses good cold-forming properties. EN standard low alloy S355J2 steel plate is produced by fully killed steel process and supplied in a normalized or controlled rolling condition.
