Stainless Steel 409 Coils

A finished steel product such as a sheet or strip that has been wound or coiled after rolling is known as a 409 steel coil. In comparison to carbon steel, Type Steel 409 Coils is a heat-resistant ferritic stainless steel with strong oxidation and corrosion resistance. Originally designed for automotive exhaust systems, this titanium stabilized grade has found use in a variety of other applications due to its excellent formability, weldability, and corrosion resistance. It contains 11% chromium, which is the minimum required amount for creating the passive surface coating that imparts corrosion resistance to stainless steel.

Stainless Steel 409M Coils

Grade Stainless Steel 409M Coils are high-tensile austenitic stainless steel with good resistance to air corrosion and exhaust gas. Coils In Ss 409m With A Lower Carbon Concentration (0.03 percent ). Where increased strength, abrasion resistance, weldability, and Slideability are required, it substitutes carbon steels and low alloy steels. It has good scaling and oxidation resistance at high temperatures, even in sulfur-rich environments. It’s used in bulk solids handling areas/bunkers, transportation (wagons), petrochemical, sugar, and agriculture. Fishing, mining and quarrying, sewage treatment plants, and general engineering.

It has good corrosion resistance at high temperatures, medium strength, good formability, and a low overall cost. Alloy 409 has a higher corrosion resistance than carbon steel and is used as a substitute. For carbon steel in mildly demanding conditions where its high corrosion resistance and high-temperature oxidation provide an advantage. It’s typically employed in situations where mechanical qualities and corrosion resistance take precedence over aesthetics.

What is the Difference Between SS 409 vs. SS 409M Coils

Alloy 409 is primarily employed in the automobile exhaust industry, although it has also found success in other industrial applications. Automotive exhaust systems, Catalytic converters, Mufflers, Tailpipes, Farm equipment, Structural support, and hangers. Transformer cases, Furnace components, and Heat exchanger tubing are just a few examples of applications for Alloy 409. And on the other hand, SS 409M Coils has a low content of carbon i.e 0.03 max.
