It complies with the GB/T 24511 standard in China, which outlines the technical specifications and test procedures for stainless steel sheets and strips.
It should be noted that various executive standards may be appropriate for particular applications and industries. When choosing and utilizing 309S stainless steel foil, consideration should be given to the unique requirements and use, concerning the pertinent standards.
What is 309 stainless steel foil used for?
Due to its excellent temperature resistance, corrosion resistance, and oxidation resistance, 309S stainless steel foil is frequently used to produce petrochemical equipment, including oil refining units, chemical reactors, and heat transfer equipment.
Heat treatment furnaces, furnace hearth pipes, and combustion furnaces are only a few examples of high-temperature furnaces and hearths that are frequently made due to their high-temperature resistance.
High-temperature resistor components: These components, which include resistance wire for electric furnaces and heaters, have a modest resistance temperature coefficient.
Boiler and heat exchanger: To assure high temperatures and corrosion resistance, boiler and heat exchanger piping, heat exchanger plates, and other elements are frequently made with this material.
In general, 309S stainless steel foil is widely used in the petrochemical industry, high-temperature equipment, resistor parts, and other fields of manufacture and application due to its excellent heat resistance and corrosion resistance in corrosive media in a wide range of applications.
What is the difference between 309 and 309S?
Seamless stainless steel is made of austenitic chromium-nickel 309S. It is a 309 derivative steel with a lower carbon content than that steel. When compared to 304 stainless seamless steel, 309S stainless steel has stronger high-temperature strength, oxidation resistance, and carburization resistance. It can withstand repeated heating below 980°C as well. The chromium level is high whereas the nickel concentration is low. It is an austenitic stainless steel with a high nickel content, which is used to produce steel that is more heat resistant. Seamless 309 stainless steel pipe does not have sulfur S content, in contrast to 309S. It has a stronger oxidation resistance than alloy 310, despite having more corrosion resistance. As a result, the steel producers produce more 309S stainless steel.

Product Manufacturing Process
1. Choose raw materials appropriate for creating stainless steel foil 309S.
2. To prepare the raw material for further processing, cut its width and length as necessary.
3. By rolling the raw material, you can compress and stretch it while also progressively reducing its thickness to get the desired thickness and width.
4. To verify the quality and purity of the foil, the rolled stainless steel foil will be pickled to remove the oxide skin, grease, and other surface contaminants.
5. To enhance the surface smoothness and flatness of the pickled stainless steel foil, physically or electrolytically polish it.
6. Run several tests on the finished 309S stainless steel foil, including surface quality inspection, mechanical property testing, and chemical composition analysis, to make sure it complies with all applicable norms and specifications.
7. Packaging the goods that pass the test, typically with materials that are moisture- and rust-proof, and shipping them from the factory.
