Composition
Stainless steel grade 20H23N18 (AISI 310s) is a complex alloy alloy austenitic, resistant to soil and atmospheric moisture, aggressive industrial gases. Produced according to GOST 5632−72. The major alloying element is chromium. It is found in numbers 22−25%. The more, the higher the corrosion resistance. When the content of > 17%, the steel becomes resistant to aggressive oxidizing environments. 12−15% Ni in the composition give the necessary plasticity and improve corrosion resistance and heat resistance. Also alloy doped with 2% manganese, 1% silicon, 0.2% carbon, thousandths of a percent of phosphorus and sulfur.

Application
Forgings, seamless pipes, parts of combustion chambers, bandages, clamps, suspension parts, fixing boilers, muffles, for operation at t° 1100 °C. recently, this steel is increasingly used in the food industry for the production of heat-resistant utensils, as well as various equipment used at the stages of food production. Steel meets the strictest hygienic and sanitary standards. It is a multifunctional convenient material. The surface of the steel pipe may be frosted, mirrored and polished. These pipes are widely used in food, pharmaceutical, chemical industry, construction and elements of advertising.
