The steel industry is in rapid development and all kinds of steel pipes have a wide application in many fields. Among all kinds of steel pipes, high-quality stainless steel pipes are the most popular as stainless steel tube has perfect corrosion resistance. Stainless steel tube can be made into different pipes for different applications. For example, after bending, stainless steel pipe can be made into stainless steel U tube for boiler and heat exchanger industry. After annealing, high-quality stainless steel pipes can have bright and smooth surface.
Though people are not unfamiliar with the stainless steel tube, there are still a lot of professional questions people don’t know.
Firstly, what makes stainless steel stainless? Stainless steel must contain at least 10.5 % chromium. This element that reacts with the oxygen in the air can form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from staining (rusting) the surface.
Secondly, what is stainless steel annealing? Annealing, or solution treatment, is employed for recrystallizing the work-hardened austenitic stainless steels and drawing chromium carbides, precipitated around the work-hardened stainless steels, into the solution. The annealing process should be completed in the high temperature environment and the stainless steel tubes can have better performance in practical use.
Thirdly, are there any differences between 304 and 316 stainless steel pipe? The answer is yes. 304 stainless steel tube contains chromium of 19% and nickel of 7%. However, 316 stainless steel tube contains 16% chromium, 10% nickel and 2% molybdenum. The moly is added to help resist corrosion to chlorides.
