The tp348 corrosion resistance of the stainless steel plate mainly depends on the alloy component (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal organizational structure, play a major role is the chromium. Chromium has a high chemical stability, can form a passivation film on the steel surface, so that the metal and the rest of the world to isolate, to protect the steel sheet is not oxidized, to increase the corrosion resistance of the steel sheet. After the destruction of the passivation film, the corrosion resistance is decreased. I funded fulfilling supply, transport facilities, mainly engaged in the production of seamless steel tubes of various steel mills. Our company can produce all kinds of stainless steel seamless pipe outside diameter φ6-1020mm, wall thickness 0.5-40mm, the Chinese material 0Crl8Ni9, 1Crl8Ni9Ti, 00Crl7Nil4M02, 0Crl7Ni12M02, 00Crl9Ni1O, 0Crl8Nil2M02Ti, 0Cr25Ni20, OOCrl9Nil3M03 etc.; U.S. Material: 301, 302 , 304, 304L, 304H, 305,316, 316L, 316Ti, 317, 317L, 310S, 321, 321H, 347H. http://tjdsgg.cn
