‌Stainless steel solution treatment is a heat treatment process that mainly improves the plasticity and toughness of stainless steel and enhances its corrosion resistance.

‌Stainless steel precision seamless pipe is a high-precision steel pipe material obtained by cold drawing or hot rolling. It has the characteristics of high precision, high finish, high pressure resis

The main reasons for pickling stainless steel heat exchange tubes include removing surface oxides and impurities, improving corrosion resistance, and extending service life.

The main reason for the black color on the surface of stainless steel heat exchange tubes is the combined effect of factors such as damaged oxide layer, surface pollutants, gas environment influence,

316l stainless steel is not food grade. It is generally used in industrial industries and has excellent corrosion resistance and high temperature resistance.

‌Stainless steel heat exchanger tube is a heat exchange element made of stainless steel, which has many advantages and a wide range of application scenarios.

‌The main differences between 304 stainless steel and 309 stainless steel are their chemical composition, corrosion resistance, high temperature performance and application areas.

The types of stainless steel processing surfaces mainly include PVD process, sandblasting, chemical treatment, mirror treatment, surface coloring, wire drawing, titanium plating, etching and anti-fing

The appearance of stainless steel should be uniformly bright, without obvious dents, scratches or rust.

304 stainless steel will rust, but it is not easy to rust, because 304 stainless steel rusts because of the chloride ions. When the two come into contact, they will react and corrode and rust.

316 stainless steel is better because it has stronger corrosion resistance and better heat resistance than 304 stainless steel.

ASTM A789 UNS S31803 Duplex Stainless Steel Pipe is a high-performance steel that combines the advantages of austenite and ferrite and is widely used in various corrosive environments.
