Get best quality 309 Stainless Plate & Sheet from top supplier, stockist in India
Table of Content
Austenitic stainless steels, such as stainless steel 309 Sheet, stainless steel 309 Plate and stainless steel 309 Coil are known for their resilience to oxidation, high temperature strength and resilience in challenging condition. The same advantages are provided by stainless steel 309S coil, plate and sheet but with less carbon, which improves weldability and lessens carbide precipitation. These grades contain 22–24% chromium and 12–15% nickel giving them excellent corrosion resistance. They have a tensile strength of at least 515 MPa, yield strength of 205 MPa, and an elongation of 40%. With a melting point between 1480°C and 1530°C, they can handle extreme heat without losing structural integrity. Preston Pipes and Alloys supplies 309 stainless steel sheet, 309 stainless sheet, 309 stainless plate and 309 stainless sheet suppliers products tested for accuracy, quality, and performance.
Stainless steel 309/309S sheet, plate, and coil work well in high-temperature applications such as furnace components, heat exchangers, and boiler baffles. Their corrosion resistance makes them suitable for chemical plants, oil and gas facilities, and waste treatment plants. In the aerospace sector, their strength and oxidation resistance are valued for aircraft and jet engine parts. The automotive industry uses them for exhaust systems that face both heat and corrosive gases. These alloys offer durability, easy formability, and reliable machinability. Due to it's long service life and reliable performance these materials are trusted by industries such as petrochemical, power generation, food processing, oil and gas and sugar production.
We offer stainless steel 309 and 309S products in thicknesses from 0.3 mm to 120 mm, widths up to 3500 mm and lengths up to 6000 mm. Sheets, plates, coils, slitting coils, and perforated coils are examples of forms. We follow ASTM A240 / ASME SA240 standards. Manufacturing involves melting in an electric arc furnace, hot and cold rolling, annealing and surface finishing. Plates are cut as per customer specification and coils is slit to the necessary sizes. Finishes include 2B, BA, No. 4, No. 8, mirror, chequered, embossed, hairline, and sandblast. All material is tested to meet exact chemical and mechanical property requirements before delivery.
We perform strict quality checks, including eddy current testing, hydrostatic analysis, pitting resistance tests, and positive material identification. Our packaging techniques safeguard goods while they are being transported, whether domestically or abroad. To guarantee a safe delivery, we use wooden crates, carton boxes, shrink wrapping, wooden pallets and wooden boxes. Every coil, plate and sheet of stainless steel 309/309S in our facility satisfies both industry standards and customer requirements. Get premium 309 stainless steel plate suppliers products with precise measurement and performance guarantees by getting in touch with us.
