This Aisi Ba Mirror 309S stainless steel flat bar is a high-temperature austenitic grade supplied in a bright annealed mirror finish, adhering to ASTM A276 standards. The 309S grade is designed for elevated temperature service, offering superior oxidation resistance up to 980°C typical, making it ideal for furnace parts, heat exchangers, and other high-heat applications. Dimensions span from 2mm to 500mm in width, with lengths customizable to project specifications.
The 309S composition includes approximately 23% chromium and 13% nickel, providing enhanced resistance to scaling and corrosion at high temperatures. The BA mirror finish delivers a surface roughness of Ra 0.1-0.5 micrometers typical, while the material retains a tensile strength of 620 MPa typical and a yield strength of 300 MPa typical for annealed conditions. This flat bar is packaged in standard export wrapping to prevent surface damage during transport and storage.
Industries such as metallurgy, chemical processing, and power generation frequently source 309S flat bars for components exposed to extreme heat and corrosive environments. Buyers in these sectors often specify fixed lengths and surface treatments to match fabrication requirements. The product is traded under FOB Shanghai or CIF terms, with shipment arranged 20-30 days after down payment or irrevocable L/C, and payment accepted via L/C sight or T/T against copy of B/L.

Prior to ordering, confirm with Jiangsu Steel Group Co., Ltd. that the 309S flat bar meets your exact requirements for high-temperature resistance, dimensional tolerances, and surface finish. Verify the material’s compliance with ASTM A276 and other relevant standards, particularly if the flat bar will be used in critical applications such as furnace linings or heat exchangers.
Discuss logistics with the supplier to align on lead times, which are typically 20-30 days after receipt of down payment or irrevocable L/C. Clarify Incoterms such as FOB Shanghai or CIF discharging port to determine shipping responsibilities and costs. Payment terms, including L/C sight or T/T against copy of B/L, should be agreed upon to ensure smooth transaction processing.
Quality assurance should include inspecting the flat bar for surface defects, verifying its chemical composition via a material test certificate, and confirming its mechanical properties. For high-temperature applications, consider third-party testing to validate the material’s performance under service conditions. Request documentation such as mill test reports to ensure traceability and compliance with your specifications.
