S32304 Material Properties
UNS S32304 belongs to the American standard dual-phase steel, the implementation standard: ASTM A240/A270M-2017
UNS S32304 alloy is a duplex stainless steel consisting of 23% chromium and 4% nickel. The corrosion resistance properties of 2304 alloy are similar to those of 316L. In addition, its mechanical properties, yield strength, are twice that of the 304L/316L austenitic grades. This feature enables designers to reduce the weight of products when designing products, especially pressure vessels.
This alloy is particularly suitable for use in the -50°C /+300°C (-58°F/572°F) temperature range. Lower temperatures can also be used under strictly limited conditions (especially for welded structures). Compared with 304 and 316 austenite, the 2304 alloy has stronger stress corrosion resistance due to its dual-phase microstructure, lower nickel content and higher chromium content.
S32304 Material Application Areas
2304 duplex stainless steel has good mechanical and physical properties, resistance to stress corrosion and other corrosion forms and good weldability, making it possible to replace austenitic stainless steel such as 304, 304L, 316, 316L and so on. It can be used in the manufacture of amine recovery equipment, fermentation equipment for hydrocarbons, etc. In addition, it can also be used as heat exchangers in the manufacturing industry, digester preheaters in the pulp and paper industry, and train seat frames in humid heat and offshore areas.
1.Most fields used by 304 and 316
2.Pulp and paper industry (chips, chip storage tanks, black or white liquid tanks, sorters)
3. Caustic solution, organic acid (anti-SCC)
4. food industry
5. Pressure Vessels (to reduce weight)
6. Mining (abrasive/corrosion)
