304 stainless steel pipe introduction

In the air or chemical corrosive medium can resist corrosion of a high alloy steel, 304 stainless steel pipe is a beautiful surface and good performance, do not have to go through plating and other surface treatment, and play the inherent surface properties of stainless steel, used in many aspects of steel.

304 stainless steel pipe is usually called stainless steel. Representative properties are 13 chromium steel, 18-8 chromium nickel steel and other high alloy steel. From a metallographic point of view, because stainless steel contains chromium, the surface of the formation of a very thin chromium film, this film is isolated from the role of oxygen intrusion in the steel. In order to maintain the inherent properties of stainless steel, steel must contain more than 12% chromium. 304 is a versatile stainless steel, which is used to make equipment and parts that require good comprehensive properties (and formability). 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China

304 stainless steel performance: 304 stainless steel is a chromium-nickel stainless steel for application, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. In the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good processability and weldability.

The use of 304 stainless steel pipe: (1) civil pipe is divided into round pipe, rectangular pipe, flower pipe, generally used for decoration, construction, structure and other aspects;

(2) Industrial pipes: industrial distribution pipe steel pipe, general distribution pipe steel pipe (drinking water pipe), mechanical structure/fluid conveying pipe, boiler heat exchange pipe, food hygiene pipe, etc. Generally used in various fields of industry such as: petrochemical, paper, nuclear energy, food, beverage, and other industries have higher requirements for fluid media pipelines.
