Nextgen Steel & Alloys is a certified manufacturer of stainless steel weld neck flanges. We use pure stainless steel alloy to manufacture these flanges. We also use automatic machinery to produce error-free products. Our products are user-friendly, so customers install them in any application very easily. All our products are reusable. Our company is expert in manufacturing these flanges for high temperature and low temperature. We also develop these flanges for high pressures. These flanges are made using nickel, molybdenum, and chromium. SS Welding Neck Flanges contain molybdenum to increase the resistance to pitting. By cold work, this alloy is hardened.
Our SS Welding Neck Flanges contain low carbon for increasing the property of resistance to corrosion, so our flanges show resistance to corrosion, fatigue strength, and creep strength. These flanges are also providing resistance to stress rupture strength, pitting resistance, etc. Our SS Welding Neck Flanges has resistance against chemical likes alkaline chloride, halide solution, acetic acid, and sulfuric acid. These chemicals cause stress corrosion, cracking and damaged products. Our flanges have more demand in the chemical industry. These flanges have higher strength at high temperatures. In the annealed condition, these flanges are non-magnetic. These welded neck flanges made of stainless steel can be cold hardened.
These flanges tolerate high temperatures without any risk of getting polluted by intergranular corrosion. Our product has mechanical properties like elongation, density, and yield strength. Our provided flanges are used in various industries like the paper and pulp industry, fabrication industry, food processing industry. These products are used in structural pipes, power plants, and used in plumping. Due to their long neck, these flanges are less expensive. At Nextgen Steel & Alloys, these flanges are go through inspection at every stage of production, from raw material buying up to packaging. We sell our flanges at a competitive price.
