Steels of different strength grades can adapt to different load-bearing requirements. S235JR is suitable for structural parts with low load-bearing requirements, S275JR is suitable for structural parts with medium load-bearing requirements, and S355JR is suitable for structural parts with high load-bearing requirements. Users can choose according to specific project requirements.
A572 Grade50/60/65 is a low alloy high strength steel. The full name of A572 Gr65 is ASTM A572 Gr65, which is a low alloy high strength niobium vanadium structural steel produced according to ASTM A572/572M of the United States. This type of steel ensures structural strength, and due to the reasonable addition of alloy elements, the performance of the steel is optimized. Compared with ordinary steel, it can withstand greater loads and is suitable for engineering fields with high requirements for structural strength.
