Duplex vs 316 stainless steel: How to choose materials?

Company / wanzhigroup

When choosing stainless steel materials in industrial, marine, or structural engineering projects, duplex stainless steel and 316 stainless steel are the two most commonly compared materials. They all have excellent corrosion resistance, but there are significant differences in strength, cost, and performance in harsh environments. This article will provide a detailed analysis of the differences between duplex stainless steel and 316 stainless steel to help you choose the appropriate material. Duplex vs 316 stainless steel Definition and Characteristics Definition and Characteristics of 316 stainless steel 316 stainless steel belongs to austenitic stainless steel and contains molybdenum (Mo) element, so its corrosion resistance in chlorine containing environments is better than that

304L Stainless steel rod wanzhi steel Low carbon SS

304L Stainless Steel Supplier | Low Carbon Stainless Steel

NEWS / wanzhigroup

304L Stainless Steel is a low-carbon version of the widely used 304 stainless steel. It has excellent corrosion resistance, good welding performance, and outstanding processing and forming ability, and is widely used in industries such as chemical, food processing, building structures, and water treatment. The letter ‘L’ represents Low Carbon, which significantly reduces the risk of intergranular corrosion after welding, making it particularly suitable for welding structures and equipment manufacturing. Chemical composition of SS 304L 304L belongs to the austenitic stainless steel series, with typical chemical compositions including: Chromium (Cr): 18-20%Nickel (Ni): 8-12%Carbon (C): ≤ 0.03% Compared with standard 304 stainless steel, lower carbon content can effectively reduce carbide precipitation

Lebanese customer's color coated steel coil SGS inspection

SGS inspection for Lebanese customer product

Company / wanzhigroup

Background: Why do Lebanese customers insist on SGS inspection? Customer Requirement: Beirut Seaside Commercial Complex Project requires color coated steel plates to withstand salt spray for at least 1000 hours and HDP coating to maintain color for 15 years. Industry pain point: “Low price and low-quality” steel coils are common in the Middle East market, and customers have suffered losses exceeding $350000 due to supplier data fraud. Anti paint peeling test Surface inspection Thickness detection Decryption of the factory inspection process The Lebanese customer purchased 2000 tons of HDP print PPGL steel coils, including two colors, RAL5015 and RAL9003. When our factory was about to complete the production of this
