AISI 321 steel is a high-alloy chromium-nickel steel with an austenitic structure, increased heat resistance and
heat resistance. The use of steel 321 is permissible at temperatures of 600-800℃, while products made of steel 321
remain in their original state for a long time.
It has no obvious magnetic properties, is unstable to oxidation and is not subjected to hardening.
The price of steel 321 is high due to the addition of titanium to the composition

Scope of application:
AISI 321 stainless steel is the most commonly used steel grade. Due to the high carbon content in the composition,
AISI 321 steel is recommended for use in industries requiring increased resistance to elevated temperatures (up to 800℃).
Steel use:
in the petrochemical, chemical and textile industries; in medicine and pharmaceuticals;
in the production of welded equipment (pipes, retorts, muffles);
in automotive and aviation construction;
in the manufacture of boiler bodies, furnace fittings, gas outlet devices, discharge collectors, expansion joints, electric heating elements;
in the production of heat exchangers and welding equipment;
in the organization of structures operating in the open air or in conditions of heating.
