从China供应商批发进口Aisi Ba Mirror 309s Stainless Steel Flat Bar — FOB条款

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.
