The corrosion resistance of stainless steel depends on the alloy elements contained in the steel. The chemical composition of S420N normalized plate, stainless steel and acid resistant steel is different. The former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The better stainless steel also contains nickel. Adding molybdenum can further improve the atmospheric corrosion resistance of stainless steel, especially the corrosion resistance of chloride containing atmosphere.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. S420N normalized plate, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
Our company provides S420N normalized plate, A302 gr. B boiler plate for customers all over the world, which is used for pressure vessels, boilers, tanks and heat exchangers in oil and gas projects. The boiler steel plate of ASTM A302 grade B /A302 gr. B can be rolled with a maximum thickness of 300 mm, and the steel performance, including mechanical properties and chemical composition, can be guaranteed to fully comply with ASTM A302 / A302M standard.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality S420N normalized plate products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
Our company stocks a wide range of hot rolled carbon steel plate distributed globally from our service centers in the U.S., Canada, Mexico, U.K, France, Shanghai, and Singapore. Customers calling for S420N normalized plate A516 a lot of times are also trying to get their arms around forecast issues. As our customers continue to work on their forecasts, IRON & Steel has options to help you conduct structured forecast reviews and put inventory strategies in place to effectively manage any impact from forecast variability.
