ASK:
ANSWER: S420N 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 S420N steel is normalized or normalized rolled
S420N steel flat and long products apply to thickness not more than 3mm-250mm
The “S” in S420N means “Structural” So, S420N is an Structural weldable quality steel grade
S420N steel apply for the sheet, plate, strip, wide flats and flats, sections, Bars and rods products.
S420N impact test temperature is -20 °C
The material No. Of S420N is 1.8902
Yield strength of S420N steel is min 320MPa
Tensile strength of S420N steel is 500-680MPa
Elongation of S420N steel not more than 18%.
