ASK:
ANSWER: S420M is the material in International standard EN10025-4. EN10025-4 specifies the technical delivery conditions for flat an long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled delivery condition in the grades and qualities in the steel products whose thickness not more than 250mm.
The delivery condition of S420M steel is thermomechanical rolled
S420M steel flat and long products apply to thickness not more than 3mm-150mm
The “S” in S420M means “Structural” “M” means “thermomechanical” So, S420M is an Structural weldable thermomechanical rolled quality steel grade
S420M steel apply for the sheet, plate, strip, wide flats and flats, sections, Bars and rods products.
S420M steel plates can be produced into heavily loaded parts of welded structures such as bridges, flood gates, storage tanks, water supply tanks. And so on.
S420M impact test temperature is -20°C
The material No. Of S420M is 1.8825
Yield strength of S420M steel is min 365MPa
Tensile strength of S420M steel is 460-680MPa
Elongation of S420M steel not more than 19%.
