Popular Grades for Comparison
•Grade 310: It has a higher nickel content and is often used in carburizing atmospheres. UNS S30815 has a lower nickel content, which gives it an advantage in reducing sulphide atmospheres.
•304H: It is a lower cost alternative to UNS S30815, but its operating temperature is limited to below about 800 °C, while UNS S30815 can be used at temperatures above about 500 °C and up to about 900 °C.
Popular Questions and Answers
Q: What is the maximum temperature that UNS S30815 can resist oxidation?
A: It can resist oxidation at temperatures up to 1150 °C.
Q: Can UNS S30815 be hardened by heat treatment?
A: This grade cannot be hardened by heat treatment, but it can be hardened by cold working.
Q: What are the typical applications of UNS S30815?
A: Typical applications include furnace components such as burners, retorts, conveyor belts, fans, jigs and baskets, rollers, walking beams, radiant tubes, electric heater elements, refractory anchors, hoods, flues, grates, expansion bellows, petrochemical and refinery tube hangers, etc.
