EN10025 S275NL low alloy steel

S275NL steel, S275N plates, under EN10025-3 standard S275NL grade, under EN10025-3 standard fine grain structural steel, we can regard S275NL material as low alloy steel

S275NL steel plate is one mainly of low alloy steel, S275NL steel plate is a hot rolled structural steels, which technical delivery conditions for normalized or normalized rolled in weldable fine grain structural steel grade. It is also regarded as DIN:TStE285 and BS:43EE
Equivalent grade :
S275NL steel plate/sheet is in EN10025 standard. It's grade Number is 1.0044. The equal material of S275NL is: UNE36081 AE 285 KT, DIN17102 T StE 285, UN Fe E 275 KT N,BS4360 43 EE ,
