Welded Stainless Steel Pipe 316ti 309s 904l C-276 Welded Tubing Customized Size

In 316Ti stainless steel, Ti is added to SUS316 steel to improve its intergranular corrosion resistance. It is applied to equipment resistant to sulfuric acid, phosphoric acid and acetic acid.
309S is a variant of 309 stainless steel with low carbon content, which is used in occasions requiring welding. The low carbon content reduces the carbide precipitated in the heat affected zone near the weld to the minimum, and the precipitation of carbide may lead to intergranular corrosion (welding corrosion) of stainless steel in some environments.
904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless and acid resistant steel. It has good activation-passivation transformation ability, excellent corrosion resistance, especially in non oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, good pitting resistance in neutral chloride ion medium, good crack corrosion resistance and stress corrosion resistance. It is suitable for sulfuric acid of various concentrations below 70 ℃, and it can resist any concentration and temperature of acetic acid under normal pressure, and the corrosion resistance of the mixed acid of formic acid and acetic acid is also very good.
C-276, known as Hastelloy C-276 in full, is a nickel chromium molybdenum alloy containing tungsten with very low silicon carbon content, which is considered as a universal corrosion-resistant alloy. It has good corrosion resistance in low and medium temperature hydrochloric acid.
