Stainless steel is a metal material Stainless steel (Stainless Steel) refers to the resistance to air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical corrosion of corrosion of the medium of steel, also known as stainless steel acid \ x0d. Practical applications, Corrosion-resistant corrosive steel is often referred to as stainless steel, and corrosion resistance of chemical steel is called acid-resistant steel. Because of the difference in chemical composition between the two, the former is not necessarily resistant to chemical corrosion, while the latter are generally The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The basic alloying elements of stainless steel are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the various uses of stainless steel. Stainless steel is easy to be chloride ion corrosion, because chromium, nickel, chlorine is the same position, the same element will be interchangeable assimilation to form the corrosion of stainless steel. \ X0d chemical composition of stainless steel corrosion resistance with the increase in carbon content (Such as 00Cr12). The main alloying element in stainless steel is Cr (carbon content) is less than 0.03% (such as 00Cr12). The main alloying elements in stainless steel are Cr (carbon content) Chrome), only when Cr When the content reaches a certain value, the steel has corrosion resistance.Therefore, the stainless steel generally Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements used stainless steel It is not easy to produce corrosion, pitting, corrosion or abrasion, and stainless steel is one of the most powerful materials in metal for building construction, and because the stainless steel has good corrosion resistance, it allows the structural parts to permanently maintain the integrity of the engineering design. Chromium stainless steel also combines mechanical strength and high elongation in one, easy parts of the manufacturing, to meet the needs of architects and structural designers.
