SS321 (321) stainless steel is an austenitic stainless steel with the following main features:
Corrosion resistance
Contains titanium (Ti), which effectively controls the formation of chromium carbide and significantly improves the resistance to intergranular corrosion at high temperatures, especially in oxidizing media.
High temperature performance
High temperature strength and creep resistance are better than 304 stainless steel. It can maintain stable performance in the temperature range of 425-815°C and is suitable for high temperature equipment (such as oil refining equipment and heat treatment furnace parts).
Processing characteristics
Good cold and hot processing performance, heat treatment temperature range of 900-1150°C, no solution treatment is required after welding (if annealing is not possible).
Applicable scenarios
Industrial field: chemical equipment, pressure vessels, pipelines
High temperature environment: steam pipelines, superheaters, gas turbine components
Special scenarios: aircraft fuel injection pipelines, hydraulic systems

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
