Stainless steel wire

Stainless steel is a high alloy steel that can resist corrosion in air or chemical corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to be treated by surface treatment such as plating, but exerts the inherent surface properties of stainless steel. It is a kind of steel used in many aspects and is usually called stainless steel. Representative performance includes 13 chromium steel, 18-8 chromium-nickel steel and other high alloy steels.

From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen that invades the steel and plays a corrosion-resistant role.
In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium.
304 is a general-purpose stainless steel that is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability).304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 is equivalent to my country’s 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 contains 19% chromium and 9% nickel.
304 is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, chemical equipment, nuclear energy, etc.
