ASTM A36 S275JR chemical composition
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.
First, let us look at ASTM A36 S275JR chemical composition and ASTM A36 S275JR mechanical properties
