Thin-walled stainless steel pipes and fittings for building water supply contain more than 12% chromium (Cr), and ferroalloys with austenite crystal structure properties formed by adding other metal elements as required. Adding nickel (Ni) can improve the ductility and toughness of the material, make it easy to form and bend. The weldability of the material can be improved by reducing the content of carbon (C). Adding molybdenum (Mo) or manganese (Mn) can improve the pitting and seam corrosion resistance of the material.Astm A240 304 304l Stainless Steel Seamless Pipe
After the reaction of chromium with oxygen and oxidant in thin-walled stainless steel pipes, a thin and tough passivation film Cr2O3 is formed on the surface, which acts as a protective film against corrosion.
If stainless steel pipes and fittings are treated by impurity removal, acid pickling and passivation process, the thickness of Cr2O3 will be increased and the uniformity of compactness will be enhanced. Polished stainless steel pipes and fittings will not only eliminate surface defects, but also make passivation film more delicate and compact, so as to reduce the probability of spot corrosion. At the same time, after finishing, the inner wall of the pipe is smooth and the friction resistance is small, which further improves the hydraulic performance of the pipe and saves consumption.Structural Carbon Steel U Beam Profile
Stainless steel pipe has high strength, strong corrosion resistance, good toughness, excellent vibration and shock resistance, low temperature is not brittle, water quality can be ensured in the process of water conveyance, and durable and renewable for decoration materials.316 Stainless Steel Coil Galvanized Iron Steel Sheet In Coil
