Mainly used where high-temperature and oxidation resistance are required:
Mainly used where excellent corrosion resistance is required:
310S is mainly designed for high-temperature and oxidation-resistant applications, while 904L is designed for highly corrosive environments.
2. Which is better for high-temperature applications?310S is generally the better choice for furnace and high-temperature applications because of its excellent oxidation resistance and thermal stability.
3. Which has better corrosion resistance?904L generally offers superior corrosion resistance, particularly in aggressive chemical environments such as sulfuric acid and other acidic media.
4. Can 310S stainless steel pipe be used in furnaces?Yes. 310S seamless pipe is widely used in industrial furnaces, heat-treatment equipment, furnace piping, and high-temperature process systems.
5. Where is 904L stainless steel tube commonly used?904L tube is commonly used in chemical processing, petrochemical, marine, pharmaceutical, pulp and paper, and heat exchanger applications.
6. What are the UNS numbers for 310S and 904L?For highly corrosive chemical environments, 904L is generally the preferred option because of its high nickel, molybdenum, and copper content.
8. Which material is better for furnace applications?310S is generally more suitable for furnace applications where high-temperature oxidation resistance and thermal stability are the primary requirements.
9. Are both materials available in custom sizes?Yes. 310S stainless steel pipe and 904L stainless steel tube can be supplied in customized outside diameters, wall thicknesses, and lengths according to project requirements.
10. Can you provide material test certificates?Yes. EN 10204 3.1 MTC can be provided upon request, including chemical composition, mechanical properties, heat number, and inspection results.
11. Which one should I choose: 310S or 904L?Choose 310S when the primary requirement is high-temperature performance. Choose 904L when the primary requirement is maximum corrosion resistance.
