Stainless steel round bars from heat-resistant steel

The features of this steel are the combination of good strength and corrosion resistance at temperatures up to 1149 * C. Due to the relatively high content of chromium and nickel, it exceeds 304 and 309 steel in most environments. It exhibits excellent resistance to carburization and nitriding. This alloy is processed similarly to 304 steel. Its chips are stringy and harden quickly. It is necessary to constantly maintain the cutting tool and use chip breakers. Good resistance to reducing and oxidizing environments up to 1149 * C. Also resistant to atmospheric and sea corrosion, salts of hydrocyanic acid. Although the alloy has a high hardening speed, it can be drawn, fluted, swelled and pressed. Complete annealing is required after cold working to remove internal stresses. Steel used, among others, for the production of parts for heating furnaces, carburizing boxes, flue gas cleaners, annealing boxes, nitric acid industry.
