The resistance of air, steam, carbon steel elbow water erosion medium and weak acid, alkali, salt and other chemical etching medium corrosion of steel. Also known as stainless steel. In practical application, it is often used to be resistant to corrosion medium corrosion of steel called stainless steel stamping elbow, and will be resistant to chemical erosion of steel called acid steel. Because of the differences in chemical composition between the two, the former is not necessarily resistant to chemical erosion, while the latter is generally not rust. Chromium stainless steel stamping elbow is set high mechanical strength and extensibility in a body, easy manufacturing and processing of parts, can contented architects and structural designers. Corrosion resistance of carbon steel elbow depends on the alloy elements in the steel.
As the stainless steel has good corrosion resistance, so it can make structural components to permanently maintain the integrity of the engineering design. Chromium stainless steel is set high mechanical strength and extensibility in a body, easy manufacturing and processing of parts, can meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere, forming an oxide film on the surface.
