S275N steel plate is Non-alloy steel for structural purposes. S275N steel’s Mechanical properties is Yield strength more than 275MPa, tensile strength 350-510Mpa.
Structural Steels S275N steel is used in many applications, combining good welding properties with guaranteed strengths. S275N steel is used above all for manufacturing highly stressed welded structures in the construction of heavy machinery, bridges and steel structures. There are many grades and the uses varied including civil and industrial engineering. High strength low alloys have replaced many structural steels where weight reduction is important (e.g. automotive) but with guaranteed strengths.
