For ASTM A36 S275JR chemical composition, A36 steel carbon content is higher than S275JR steel, other elements such as Mn, Si, Cu, etc. is lower than that of EN10025-2 S275JR steel.ASTM A36 S275ASTM A36 S275JR are common used steel materials in construction. ASTM A36 steel is produced according to ASTM A36/ A36M standard, while S275JR steel is produced according to EN10025-2 standard. Both ASTM A36 S275JR steel materials are mild steel. They have a lot in common and also many differences.
