Stainless steel types introduction


Stainless steel is a corrosive alloy steel that consists of iron, carbon, chromium and other elements. There are many types of stainless steel, and common ones include:

Chromium stainless steel: contains more than 10.5%chromium, has good corrosion resistance, and is often used in making kitchenware, tableware, sanitary ware, etc. Such SS410,SS420.

Nickel stainless steel: In addition to chromium, it also contains more than 8%nickel. It has better corrosion resistance and heat resistance. It is often used in the production of chemical equipment, ships, food processing equipment, etc. Such as A2 A4, SS304, SS316.

Titanium alloy stainless steel: contains titanium and aluminum elements, which have good heat resistance and corrosion resistance, and are commonly used in high temperature equipment and chemical equipment. Such as 316Ti.

Duplex stainless steel: contains equal proportion of Austenite and iron, with good strength and corrosion resistance, and is commonly used for making pipelines and storage tanks. Such as duplex 2205, duplex 2207.
