Product Details

Ferritic Stainless Steels (400 series) contain 15% to 30% chromium and have a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes also contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance. It is mostly used for manufacturing atmospheric resistance. , Water vapor, water and oxidizing acid corroded parts.

The price of Ferritic Stainless Steels are not only relatively low and stable, but also has many unique functions and advantages. Facts have proved that in many applications where only austenitic stainless steels (300 series) can be used, ferritic stainless steels are excellent. As an alternative material, ferritic stainless steel does not contain nickel, and the main elements are chromium (> 10%) and iron. Chromium is a particularly corrosion-resistant stainless steel element, and its price is relatively stable. Among them, 00Cr18Ti ferritic stainless steel is used to transport dilute nitric acid, ammonium nitrate, chemical fiber (polyethylene, polyester, acrylonitrile, glycol, etc.) atmospheric and low pressure pipelines and storage tanks.

Applications:electronic and electrical appliances, metal stamping parts, spring shrapnel, pad diaphragm, precision parts, accessories, bellows, seals, Etching part kitchen equipment sink (SINK) general drawing material (high surface requirement) gas stove-surface requirement high refrigerator (freezer tank) electrical appliance washing machine, Construction material MIRROR (Mirror material) for the Construction Tube of Microwave oven Decoration Tube of drying Machine and Grinding the window of inside and outside Decoration material of Elevator, door Chemical equipment Heat Exchanger Boiler, Tank chemical furnace special purpose transport equipment container iron Road vehicles / automobile industry / water industry / construction / home appliances / environmental protection industries / industrial facilities etc
