FAQ

Q1: How does 310S compare to Inconel 601 in high-temperature service?

A: 310S offers comparable oxidation resistance up to ​1,100°C (2,012°F) at ​60% lower cost. Upgrade to Inconel only above ​1,200°C (2,192°F) or for extreme sulfur environments.

A: Use ​GTAW with ER310 filler, preheating to ​150-200°C (302-392°F) for thickness >6mm. Post-weld heat treatment ​not required for most applications.

A: Specify our ​Pre-Oxidized Finish – pre-stabilized oxide layer reduces post-processing scaling by ​90%.
