Heat resistant steel AISI 309 / 1.4828 EN

Steel AISI 309 / 1.4828 EN / 20Х23Н13

Stainless steel AISI 309 is a heat resistant alloy with additions of Nickel and chromium components. The alloy composition is quite balanced, which allows him to not succumb to oxidative processes and to retain strength in a wide temperature range. Features Steel grade 309 and 309S are of good compliance in the treatment, the alloy is perfectly welded all types of welding. This allows you to find the steel most widely used in all sectors of the economy. Such characteristics of steel as the upper temperature limit of use is about a thousand degrees. The experts do not recommend the use of steel structures with high strength requirements at temperatures exceeding 800°C. this increases the brittleness of the alloy due to the formation on the surface of the scale. The application and use of AISI 309 Alloys based on steel AISI 309 find wide application in all fields where there is high temperature. Having increased strength and resistance to corrosion, steel is durable in all types of designs. Mainly steel is used in the production of parts and subassemblies. Alloy make: • publishing and packaging; • conveyors for furnaces; • rebar for steelworks; • pipelines for oil and gas industry. In addition, the alloy used in construction, mining industry, chemical industry. Chemical composition of steel EN 1.4828
