ASK:
ANSWER: S420NL is the material in International standard EN10025-3. EN10025-3 specifies the technical delivery conditions for flat an long products of hot rolled weldable fine grain structural steels in the normalized/normalized rolled delivery condition in the grades and qualities in the steel products whose thickness not more than 250mm.
The delivery condition of S420NL steel is normalized or normalized rolled
S420NL steel flat and long products apply to thickness not more than 3mm-250mm
The “S” in S420NL means “Structural” So, S420NL is an Structural weldable quality steel grade
S420NL steel apply for the sheet, plate, strip, wide flats and flats, sections, Bars and rods products.
S420NL impact test temperature is -50 °C
The material No. Of S420NL is 1.8912
Yield strength of S420NL steel is min 320MPa
Tensile strength of S420NL steel is 500-680MPa
Elongation of S420NL steel not more than 18%.
