S355NL is a low - alloy high - strength structural steel specified in EN 10025 - 3:20042. It is a normalized steel (fine - grained steel)1. Here is a detailed introduction:

 

Chemical Composition4

Carbon (C): 0.12% - 0.20%. It is a main element that increases strength and hardness.

Silicon (Si): 0.005% - 0.70%. It is an alloying element that improves strength and hardness.

Manganese (Mn): 1.00% - 1.60%. It is an alloying element that improves strength and hardness.

Phosphorus (P): Not more than 0.010%. It is an impurity element, and its content needs to be controlled to ensure toughness and corrosion resistance.

Sulfur (S): Not more than 0.005%. It is an impurity element, and its content needs to be controlled to ensure toughness and corrosion resistance.

Chromium (Cr): Not more than 0.30%. It is an alloying element that improves corrosion resistance and high - temperature strength.

Molybdenum (Mo): Not more than 0.40%. It is an alloying element that improves corrosion resistance and high - temperature strength.
