For S355J2G1W steel for bridge construction ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B S355J2G1W steel for bridge construction is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.

The main characteristics of S355J2G1W steel for bridge construction, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.

The Egypt customer ordered 130 tons S355J2G1W steel for bridge construction stainless steel plate in stock, and this batch has left port today for its destination today(October 25th, 2019). 316l stainless steel is molybdenum-bearing austenitic stainless steel. This material has better corrosion resistant property than 304/314L for it's higher Ni and Mo content. (it is considered to be marine grade stainless steel, not suitable for warm sea water treatment). 316L austenitic stainless steel supplied by our company has good formability and weldablity, additionally it is proved to have excellent properties of tensile, creep and stress-rupture strengths in elevated temperature environment.
