Problems solved by technology

The stainless steel pipe prepared by the method of the invention has strong corrosion resistance, good internal and external surface quality, and low manufacturing cost. However, in actual use, the stainless steel is often exposed to water, which is easy to breed bacteria and does not have a bactericidal function.
[0004] The patent application with the publication number CN104651742A discloses a high-strength anti-corrosion stainless steel for metal doors and windows and its processing technology. The components are: C, Mn, Si, P, S, Nb, V, Ti, Al, N, H, Cu , Cr, Ni, Mo, lanthanum, cerium, praseodymium, the balance is Fe and unavoidable impurities; the stainless steel of the invention has strong corrosion resistance, high transverse yield strength, and excellent low temperature toughness, but the stainless steel is used in Doors and windows are often exposed to the air and sunlight. The stainless steel does not have the function of anti-ultraviolet rays. Strong ultraviolet rays will easily damage the surface of the stainless steel and cause damage to human skin, and at the same time shorten the service life of the stainless steel.
