Can 304 substitute for 310S to save cost?｜Foshan Huili Metal Technology Co., Ltd.（佛山市惠利金属科技有限公司）

Conclusion：No — 310S is heat-resistant (high Cr/Ni, 1000℃+); 304's high-temp strength and oxidation resist fall far short and it scales above temperature.

This conclusion is compiled from our technical article: Company & brand (310S与304耐热对比经验). Verify against your actual duty; call us to discuss.

Selection notes

310S (25Cr20Ni) to 1150℃; 304 strength drops above 870℃ — don't substitute 304 for heat duty.
