Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of q345b s355jr steel plate, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

Mechanical properties of S355J2 plate: yield strength Rp0.2 ≥ 275MPa, tensile strength Rm: 450 - 600MPa, elongation A ≥ 18%, - 20℃ impact energy ≥ 47J, tensile section shrinkage Z ≥ 35% in thickness direction. The q345b s355jr steel plate, S355J2 steel plate has excellent internal quality, high density and stable performance. S355J2 structural steel is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields.
According to the latest statistics of alacero, the consumption of finished steel q345b s355jr steel plate products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.
