2b Cold Rolled 409 Stainless Steel Plate 1000mm 420 Sheet 410S 416 304 For Curtain Walls

Cold Rolled SS 409L 410S 416 420 304 Stainless Steel Sheet For Curtain Walls

Production Description

Ferritic stainless steel (400 series) has a chromium content of 15% to 30% and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes 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. , Parts corroded by water vapor, water and oxidizing acid.

The price of ferritic stainless steel is not only relatively low and stable, but also has many unique features and advantages. It has been proved that ferritic stainless steel is an extremely high-quality stainless steel in many applications that were originally considered only austenitic stainless steel (300 series).

Features Of 400 Series Stainless Steel

The chromium content is 12% to 30%, and the body-centered cubic lattice of ferrite is used as the matrix structure of stainless steel at high temperature and normal temperature. This type of steel generally does not contain nickel, and some contain a small amount of molybdenum, titanium or niobium and other elements, and has good oxidation resistance, corrosion resistance and resistance to chloride corrosion cracking.

According to the chromium content, ferritic stainless steel can be divided into three categories: low chromium, medium chromium and high chromium. According to the purity of the steel, especially the content of carbon and nitrogen impurities, it can be divided into ordinary ferritic stainless steel and ultra-pure ferritic stainless steel. 

Ordinary ferritic stainless steel has shortcomings such as low temperature and room temperature brittleness, notch sensitivity, high intergranular corrosion tendency, and poor weldability. Although this type of steel developed earlier, its industrial application has been greatly limited.
