S355NL steel is Non-alloy steel for structural purposes. S355NL steel’s Mechanical properties is Yield strength more than 355MPa, tensile strength 450-630Mpa.
Structural Steels S355NL is used in many applications, combining good welding properties with guaranteed strengths. S355NL steel is used above all for manufacturing highly stressed welded structures in the construction of heavy machinery, bridges and steel structures. S355NL steel is available for application temperatures below -20 °C. There are many grades and the uses varied including civil and industrial engineering. High strength low alloys have replaced manystructural steels where weight reduction is important (e.g. automotive) but with guaranteed strengths.
