  First of all, the stainless steel reducer is not easy to rust, and then why does the stainless steel rust?

  Socket Weld Stainless Steel Reducer is not easy to rust and has a great relationship with the composition of stainless steel. In addition to iron, there are chromium, nickel, aluminum, silicon and so on. Generally, the chromium content of stainless steel is not less than 12%, high even 18%. After adding elements such as chromium steel, can change the performance of the steel, such as the molecular structure of the steel is more uniform, on the surface of steel are more likely to generate a dense layer of oxide film and so on, thus greatly improve the corrosion resistance of stainless steel. Therefore, stainless steel can resist fire, water, acid, alkali and various solutions to its corrosion, not rust. Scientists found that the internal structure of steel more uniform, all sorts of composition are the more cohesive, corrosion, invasion of the more difficult, plus surface and attached to a layer of oxide film, just like to put on the armor steel, nature will not easy to rust.

  Why does stainless steel reducer rust? When reducing pipe fittings stainless steel reducer surface appear brown rusty spot (or points), big surprised: people think "stainless steel reducer is not rusty, rust is not stainless steel reducer, is likely to be the problem of steel". In fact, this is a kind of one-sided wrong view of the lack of understanding of stainless steel. Stainless steel also rusts under certain conditions.
