Frequently Asked Questions
Q1: How to prevent welding cracks in 310S tubing?
A: Use ER310 filler metal with controlled heat input (max interpass temp: 150°C)
Q2: Maximum continuous service temperature?
A: 1150°C for oxidation resistance; limit to 800°C for long-term load-bearing
Q3: Difference between 310S and 309S?
A: 310S has higher Ni/Cr (25Cr-20Ni vs 22Cr-12Ni) for superior heat resistance
Q4: Machining tips to avoid tool sticking?
A: Use carbide tools with slow speeds and high lubricant flow
