SA588 Gr A weathering steel plate for boilers and pressure vessels

316 Vs 304: ASTM 316L(1.4404) is a low-carbon austenitic chromium-nickel-molybdenum steel. Due to the addition of 2-2.5% molybdenum, the corrosion resistance of the stainless steel 316L is significantly better than that of the standard austenitic grades 304 and 304L, SA588 Gr A weathering steel plate. The 1.4404 material is resistant to intercrystalline corrosion when welded! but not resistant to sea water. Best corrosion resistance is given with a polished surface. This material is comparable to 1.4401.

The SA588 Gr A weathering steel plate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The SA588 Gr A weathering steel plate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than SA588 Gr A weathering steel plate, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). SA588 Gr A weathering steel plate, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.
