Many seamless pipes are now made of stainless steel. Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. is a factory specializing in the production of stainless steel seamless pipes.

Stainless steel is steel that is not easy to rust. In fact, some stainless steels have both rust resistance and acid resistance. This is due to the formation of a chromium-rich oxide film on the surface, and the rust resistance and corrosion resistance are relative.

Tests have shown that the corrosion resistance of steel in weak media such as the atmosphere and water and oxidizing media such as nitric acid increases with the increase of the chromium content in the steel. When the chromium content reaches a certain percentage, the corrosion resistance of the steel changes suddenly. , That is, from easy to rust to not easy to rust, from no corrosion resistance to corrosion resistance.

There are many ways to classify stainless steel. According to the organization structure at room temperature, there are martensitic, austenitic, ferritic and duplex stainless steels. According to the main chemical composition, it can be basically divided into two systems: chromium stainless steel and chromium-nickel stainless steel. According to the purpose, there are nitric acid-resistant stainless steel, sulfuric acid-resistant stainless steel, seawater-resistant stainless steel and so on. According to the type of corrosion resistance, it can be divided into pitting corrosion-resistant stainless steel, stress corrosion-resistant stainless steel, and intergranular corrosion-resistant stainless steel. According to the functional characteristics, it can be divided into non-magnetic stainless steel, free-cutting stainless steel, low-temperature stainless steel, high-strength stainless steel and so on.

Because stainless steel has excellent corrosion resistance, formability, compatibility, and toughness in a wide temperature range, it has been widely used in heavy industry, light industry, daily necessities industry, building decoration and other industries.
