This 304 stainless steel material without titanium and niobium has a tendency to 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 to give full surface properties to 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 304 stainless steel chrome-nickel steel. From the perspective of metallography, because stainless steel contains chromium and the surface forms a very thin chromium film, this film is isolated from the intrusion of oxygen in the steel to resist corrosion. In order to maintain the corrosion resistance inherent in stainless steel, steel must contain more than 12% chromium. Used in applications where soldering is required. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, and the precipitation of carbides may cause intergranular corrosion of the stainless steel in certain environments .
