301 Material rust causes editor broadcast

1. There are chloride ions in the use environment. Chloride ions are found in salt, sweat, seawater, sea breezes, and soil. Stainless steel in the presence of chloride ions in the environment, corrosion is fast, even more than ordinary mild steel. So there are requirements for the use of stainless steel environment, and the need to often wipe, remove dust, keep clean and dry. (That would give him a "misuse.") The United States has an example: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been in use for nearly a hundred years. In the 1990s, it planned to replace it, but the oak material was not modern enough and stainless steel was used.

2. No solution treatment. Alloying elements are not dissolved in the matrix, resulting in low alloy content and poor corrosion resistance of the matrix tissue.

3. This titanium - and niobium - free material has a natural tendency to intergranular corrosion. The addition of titanium and niobium, coupled with stabilization treatment, can reduce intergranular corrosion. A high alloy steel that can resist corrosion in the air or chemical corrosion medium, stainless steel is a beautiful surface and good corrosion resistance, without surface treatment such as plating, and play the inherent surface properties of stainless steel, used in a variety of steel, usually called stainless steel. Representative performance of 13 chromium steel, 18-8 chromium nickel steel and other high alloy steel.
