High-temperature service is intended for SS 310 grade(ss 310 chemical composition), which combines excellent high-temperature qualities with strong ductility and weldability. If there are no reducing sulphur fumes present, it can withstand continuous use at temperatures of up to 1150°C without succumbing to oxidation. At up to 1040°C, it is also employed for intermittent service. Grade 310S (UNS S31008) is utilized when the application environment includes moist corrodents at temperatures lower than what is generally called “high temperature” service.
In comparison to SS 310, 310S has less carbon, which lessens its high-temperature strength. Although different grades are typically utilized in this environment, these austenitic grades provide remarkable toughness, even at cryogenic temperatures. Grade 310L (and proprietary variations of this grade) is a very particular corrosive environment version of 310 with a 0.03 percent maximum carbon content, often utilized in the manufacturing of urea.

Benefits of SS 310
The advantages of stainless steel products are numerous and meet or surpass the requirements of the application. The strong resilience of these stainless steel, which allows for their usage in demanding situations, is their main advantage. SS sheets and plates are attractive and difficult objects due to their bright and simple-to-maintain surface. A number of tests are carried out to confirm the durability of 310 stainless steel round bars.
