ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually A633 Grade A chemical composition it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.
EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are A633 Grade A chemical composition, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.
