Accurate Metals & Alloys is one of the famous establishments in the city of Mumbai because of the quality of our Stainless Steel 309 Coils that we have been manufacturing, stocking, and exporting worldwide.
The Stainless Steel 309 Coils are the austenitic versions of stainless steel. The SS 309 Coils are utilized equally in the conventional and commercial regions. These SS 309 Coils are essentially requested in only these two profiles and they are Stainless Steel 309 Hot Rolled Coils and Stainless Steel 309 Cold Rolled Coils.

The Stainless Steel 309 Coils are the austenitic forms of stainless steel. They have a combination of the elements chromium and nickel. These SS 309 Coils are majorly obtained and consumed for the high temperatures applications. The greater amounts of chromium and nickel in the SS 309 Coils makes them extremely resistant to corrosion. The SS 309 Coils also possess a good resistance against the act of oxidation. Between the range of room temperatures and moderately higher temperatures, the SS 309 Coils gain heat resistance, providing good strength simultaneously. The one and only main difference between the Stainless Steel 309 grade alloy and the Stainless Steel 309S grade alloy is the content of the carbon element in their mixtures. Here, the SS 309S grade has a higher level of carbon in them which is why the carbide precipitation reduces and the welding quality is further improved. The SS 309 Coils exhibit a higher resistance against the sulphite liquors. Generally, this SS 309 grade is claimed to be the heat-resisting alloy. The Stainless Steel 309 Coils are much better functional under the marine environments in comparison to the world-class Stainless Steel 304 Grade Coils.
The Stainless Steel 309 Coils have multiple objects to be fabricated in and have several objectives to serve. The SS 309 Coils are applied for both, domestic and industrial purposes. A few of the many applications of SS 309 Coils are Aircraft and jet engine parts, kiln liners, carburizing annealing products, boiler baffles, heating units, heat exchangers, refineries, auto exhaust components, sulphite liquor handling systems, and chemical and petrochemical processing equipment.
