Accurate Metals & Alloys is a Mumbai-based establishment in the iron and steel industry. We are one of the few great steel companies that manufacture, export, and stock the Stainless Steel 409 Coils and all the other stainless steel products.
The Stainless Steel 409 Coils are ferritic types of stainless steel. Their applications are completely inclined toward their usage in industrial work. A couple of SS 409 Coil profiles are available in the steel industry. Still, commercialists prefer two profiles of SS 409 Coils to maximum over the other SS 409 Coil profiles, and the two profiles are the Stainless Steel 409 Hot Rolled Coils and the Stainless Steel 409 Cold Rolled Coils.
The Stainless Steel 409 Coil alloys are a member of the ferritic series of stainless steel. The Stainless Steel 409 Cold Rolled Coils (CR) are much more expensive than the Stainless Steel 409 Hot Rolled (HR) as the hot rolled coils require lesser time to be manufactured and cooled while the cold rolled coils take in a lot of work in their engineering period. The SS 409 Coils provide a good amount of resistance against corrosion caused by the higher range of temperatures. In the chemical composition of the SS 409 grade, they have a moderate amount, about 11% of chromium, a small amount of titanium, and low concentrations of carbon in them, which assist the coils in preventing the formation of austenite. The titanium in the SS 409 Coils stabilizes them and avoids the excessive hardening of the SS 409 Coils during their welding. The titanium in the SS 409 grade also averts and stops the formation of chromium carbides.
