304 stainless steel channel, how much is one meter?
The former is not necessarily resistant to chemical media corrosion, while the latter are generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel
The basic alloying elements of stainless steel, as well as nickel, molybdenum, titanium, niobium, copper, nitrogen and so on, to meet the various requirements for the use of stainless steel structure and performance. Stainless steel is easy to chloride corrosion, because chromium nickel chloride is collocated elements, elements will be collocated to form stainless steel corrosion exchange assimilation. The corrosion resistance of the chemical composition of stainless steel with increased carbon content decreased, therefore, the carbon content of most stainless steel are relatively low, the maximum of no more than 1.2%, some steel Wc (carbon) or even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), which is corrosion resistant only when the Cr content reaches a certain value. Therefore, stainless steel in general Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements, stainless steel is not prone to corrosion, pitting corrosion or corrosion or wear. Stainless steel is one of the highest strength materials used in construction. Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain the integrity of Engineering design. Chromium containing stainless steel is also a combination of mechanical strength and high extensibility, easy to process and meet the needs of architects and structural designers.
Stainless steel is a metal material, stainless steel (Stainless, Steel) refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion, also known as stainless acid resistant steel. In practical application, the steel which is often corroded by weak corrosive medium is called stainless steel, and the steel which is resistant to chemical medium is called acid resisting steel. Because of the difference in the chemical composition of the two,
