Would the Stainless Steel Material Get Rusty

- Jul 14, 2020-

  1. Stainless steel is divided into many grades, which are stainless steel 201, 304, 316, 321 and so one. Due to different costs, some unqualified manufacturers will use stainless steel 201 as stainless steel 304. In this way, due to the different nickel content of stainless steel 201, it may cause rust.

2. If the stainless steel 304 material gets rusty still, please see the following explanation:

Stainless steel will not rust under normal circumstances, but when exposed to chlorine or harsh environments, especially after the passivation layer on the surface is mechanically or chemically damaged, it is easier to rust than usual, so in this environment It is easier to rust. The surface of the stainless steel products we usually use is passivated, and the thickness of the chromium oxide film on the surface is much thicker and denser than the naturally formed oxide film on the fresh surface. Therefore, the stainless steel electric heating tube will also get rusty.
