”CHOOSE PUXIN METAL AND LOOK FORWARD TO HEARING FROM YOU！“
AISI 309 stainless steel bar has become the preferred material for harsh industrial scenarios such as boiler manufacturing, chemical equipment, high-temperature furnaces and heat exchange systems due to its high alloy properties and excellent high-temperature resistance. As an optimized and upgraded model of austenitic stainless steel, 309 stainless steel material forms a dense and stable Cr2O3 oxidation protective layer in a high-temperature environment through precise proportioning of core elements such as carbon, silicon, manganese, chromium, and nickel (chromium content ≥23%, nickel ≥13%), effectively isolating the invasion of oxidizing corrosive media, and can maintain structural stability at a long-term working temperature of 1150°C. Its heat resistance and anti-carburization ability are significantly better than conventional 304/0Cr19Ni9 stainless steel.
309 stainless steel bar adopts the international standard AISI 309/S30900 certified formula, and strengthens the grain boundary bonding through low sulfur and phosphorus impurity control and solid solution treatment process. It has the dual advantages of high-temperature strength and room-temperature toughness, and exhibits excellent corrosion resistance in acidic media such as sulfuric acid and nitric acid and alkaline environments. The bars are formed by precision cold drawing/hot rolling, with a surface finish of Ra0.8μm, which can meet the machining requirements of key components such as high-temperature and high-pressure pipelines, reactor support components, burner nozzles, etc., and are suitable for long-term service under frequent thermal cycle conditions. The service life is more than 3 times that of ordinary materials.
