Introduction of S355NL steel plate

S355NL steel plate is a low-alloy high-strength steel plate that implements European standards. The yield strength and tensile strength in mechanical properties are similar to those of my country's Q345 series of low-alloy high-strength steel plates.

 

S355NL steel plate executive standard: EN10025-3. Full name: Normalized/Normalized Rolled Weldable Fine Grain Structure Steel Plates, this standard replaces EN 10113-1:1993 together with EN 10025-1

 

Hot-rolled weldable fine-grained structural steel products part: General conditions and EN 10113-2:1993 Hot-rolled weldable fine-grained structural steel products part 2: Conditions for normalized/normalized rolled steel.

 

When the temperature is not lower than -20°C, the minimum value of impact energy is specified, which is represented by N, and when the temperature is not lower than -50°C, the minimum value of impact energy is specified, which is represented by NL.

 

Chemical composition of S355NL steel plate:

C carbon: ≤0.22;

Si silicon: ≤0.55;

Mn manganese: ≤1.60;

P phosphorus: ≤0.025;

S sulfur: ≤0.025;

Cu copper: ≤0.55;

 

Mechanical properties of S355NL steel plate:

Tensile strength: 450—630MPa;

Yield strength: 275—355MPa;

Elongation: 21%;

 

S355NL steel plate implementation standard: The European standard "EN10025" is implemented, and the quality requirements must be met before leaving the factory.

Delivery status of S355NL steel plate: It is delivered in the heat treatment status of normalizing and hot rolling.

Application of S355NL steel plate: structural parts such as construction machinery, mining machinery, metallurgy and environmental protection, water conservancy and hydropower.
