1. Chloride ion exists in the use environment
Chloride ions are widely present, such as salt, sweat, sea water, sea breeze, soil, and so on. Stainless steel in the presence of chloride ions, corrosion is very fast, even more than ordinary low carbon steel. Therefore, there is a requirement for the use environment of stainless steel, and it is necessary to wipe frequently to remove dust and keep it clean and dry.
2, no solution treatment
The alloying elements are not dissolved in the matrix, resulting in a low content of the matrix microstructure and poor corrosion resistance.
3. This material without titanium and niobium has a tendency to be intrinsic intergranular corrosion.
The addition of titanium and niobium, together with a stable treatment, can reduce intergranular corrosion. A high-alloy steel that resists corrosion in air or chemically corrosive media. Stainless steel has an aesthetically pleasing surface and good corrosion resistance. It does not require surface treatment such as plating, but also exhibits the inherent surface properties of stainless steel. One of the aspects of steel, commonly referred to as stainless steel. Representative properties include high-alloy steels such as 13 chrome steel and 18-8 chrome nickel steel.
