310S is also called 2520 China Standard (GB):0Cr25Ni20

ASTM: 310S, BS EN: 1. 4845

Characteristic: Suitable for making all kinds of furnace components, the highest temperature is 1300 C, and the continuous use temperature is 1150 C. 310S is a standard method for stainless steel in the United States. Its domestic label is (2520) 0Cr25Ni20. It is an austenitic stainless steel. S in 310S refers to the special use of this stainless steel. 0Cr25Ni20 (310S) characteristics – high temperature oxidation resistance, high temperature strength. Usage – Exhaust Bellows, Microwave Heater, Tube, High Temperature Furnace Gallbladder, Cremation Furnace and other steel grades requiring heat resistance, high temperature/high temperature contact parts.

310S:25Cr-20Ni series high alloy stainless steel has excellent oxidation resistance at high temperature and is suitable for heat-resistant parts below 1000 C.
