Information on 409m Chemical Composition

409m chemical composition

The modified version of SS 409, or SS 409M, has a decreased carbon content of about 0.03 percent compared to the original. Where increased strength, resistance to abrasion, weldability, and slide-ability is required, this takes the role of carbon steels and low-alloy steels. It has good scaling & oxidation resistance at high temperatures, especially in sulfur-containing atmospheres. For handling bulk solids, it is used in areas/bunkers, transportation, sugar, petrochemical, agricultural, fishery, mining & quarrying, sewage systems, and general engineering industries.

409m Chemical Composition

Compared to the original form, 409m chemical composition has a slightly different chemical make-up. This grade contains 0.03% carbon, 1% silicon, 0.5 to 1.5 percent manganese, 10.80 to 12.50 percent chromium, 1.5 percent nickel, 0.04% phosphorus, 0.03% sulphur, and 0.03 percent nitrogen, among other components.

Applications of 409M Grade

Alloy 409M is a steel that has mostly been employed in the automobile exhaust industry but also found widespread use in a variety of other industrial applications. As a result, Alloy 409M Sheets are also likely to be used in gas heaters and other high-temperature applications. They are also employed in a variety of industries, including the railroad, chemical, and cement industries.
