Is stainless steel a metal material?

Dec. 25, 2019

Stainless steel is a metal material stainless steel refers to steel that is resistant to erosion by weakly corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. Steels that are resistant to erosion by weakly corrosive media are often referred to as stainless steels, and steels that are resistant to chemical media erosion are referred to as acid-resistant steels. Because of the difference in chemical composition between the two, the former is determined to be resistant to chemical media erosion, and the latter is generally equal. It is stainless. The corrosion resistance of stainless steel depends on the alloying element \ x0d contained in the steel. The basic alloy elements of stainless steel are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the requirements of various applications on the structure and function of stainless steel, stainless steel is easily attacked by chloride ions, because chromium, nickel, and chlorine are isotopes. Isotopes will be exchanged and assimilated to form the corrosion of stainless steel. \ X0d The chemical resistance of stainless steel decreases with the increase of carbon content. Therefore, most the stainless steels have lower carbon content. Over 1.2%, the Wc of some steels is even lower than 0.03% (such as 00Cr12). The primary alloying element in stainless steel is Cr. Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a Cr 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, rusting or abrasion. Stainless steel is still one of the strongest materials in construction metal. Because stainless steel has excellent corrosion resistance, it can make layout components permanently link the integrity of engineering design. Chromium-containing stainless steel also combines mechanical strength and high elongation, which is easy to process and manufacture components, which can meet the needs of architects and layout designers.

Do you know the three characteristics of Stainless Steel Seamless Pipe China?

Stainless steel pipes can be encountered everywhere in our daily use. I believe that many friends are asking why we are in contact with so many stainless steel pipe products in our lives. Therefore, Welded Stainless Steel Pipes Manufacturer China starts from the three characteristics of stainless steel pipes Help everyone to better understand.

1.Corrosion resistance

Most stainless steel products require good corrosion resistance. Stainless steel pipes are similar to Type I and II tableware, kitchen appliances, water heaters, water dispensers, etc. Some foreign merchants also perform corrosion resistance tests on the products: warm to boiling with an NaCl aqueous solution. After a period of time, the solution is to drain, wash and dry, determine the weight loss to determine the degree of corrosion.

2.Welding workability

Welding performance requirements vary from product to product. A tableware usually does not require welding performance, even including some pot companies. However, most products require good welding performance of raw materials, such as second-class tableware, insulation cups, steel pipes, water heaters, water dispensers, etc. Our company also has Stainless Steel Seamless Pipe on sale, welcome to consult.
