Ferritic SS 430
Ferritic SS 430 has a high amount of chromium content (16-18%) in its composition which ensures its commendable resistance to corrosion and oxidation, its maximum scaling temperature is about 820°C. This composition helps the alloy to resist well in nitric acid and sulphur environments, hence it can be widely used in chemical applications.
The alloy also has appreciable resistance to domestically used liquids (soaps), alkaline solutions, dilute organic solutions etc., but it is not very well resistant to the halogen group (Cl, Br, Fr) and a chloride solution can induce stress corrosion cracking. The presence of alpha iron in the grain structure gives the alloy its magnetic properties similar to other Ferritic stainless steel alloys.
