What welding rod or wire should be used for 310s?
1 Answers
310S stainless steel should be welded using ER-310 welding wire or A402 welding rod. 310S (0Cr25Ni20) is an austenitic chromium-nickel stainless steel with excellent oxidation resistance and corrosion resistance. Due to its high percentage of chromium and nickel, 310S has much better creep strength and can operate continuously at high temperatures, exhibiting good high-temperature resistance. More details are as follows: Advantages of 310S stainless steel: 310S stainless steel has good high-temperature resistance. When the temperature exceeds 800°C, it begins to soften, and the allowable stress starts to decrease continuously. The maximum service temperature is 1200°C. ER310 stainless steel welding wire: ER310 stainless steel welding wire, with a molten metal composition of 25Cr-20Ni, is mostly used for welding 310S stainless steel. It is suitable for welding dissimilar metals and alloy steels and high-carbon steels with high self-hardening properties.
