Performance and application of 304 stainless steel pipe

Written by

304 stainless steel pipe is the most widely used of heat-resisting stainless steel pipe, the chemical composition of the steel grade is the most main in the chromium containing 19% and 9% of nickel element, so called in Chinese gb 0 cr19ni9 (0 cr18ni9) stainless steel pipe. The use of 304 stainless steel pipes is used in food equipment, general chemical equipment, atomic energy equipment and so on.

Stainless steel pipe rust steel is more adaptable. The same is true for high temperature, with a maximum temperature of 1200 degrees Celsius, which can satisfy most of the use environment.

304 stainless steel pipes generally have very good corrosion resistance, and of course the anti-crystal intergranular corrosion performance. As an atmosphere or chemical corrosion medium can also be effective enough for corrosion resistance of high alloy steel, 304 stainless steel pipe surface are usually very beautiful, so also is very suitable for home decoration and railings, handrails, etc., and keep the stainless steel pipe ecru, even no specialized in surface treatment, such as color of plating can give full play to the advantages of stainless steel is natural.

Also from the perspective of the metallography of stainless steel with 304 stainless steel chemical composition containing chromium element, so it would be easy to formed in the surface layer is very thin and dense chromium film, this is the role of film of keep the outside world can invade and the corrosion of the stainless steel substrate oxygen. In order to be able to make a powerful chrome protective film, the chemical composition of the 304 stainless steel pipe must be added to the chromium element above 12%, so as to maintain the natural corrosion resistance of the stainless steel.
