Specifications
- Plate, Sheet & Strip: ASTM A240
- Rod & Bar: ASTM A479
As in-service temperature levels have been raised over time, the importance of 310 has increased. Chromium content contributes to heat resistance. However, straight chromium grade stainless steels (400 series) are only effective up to 1250º F (700º C). Austenitic grades, particularly 347 Stainless and 316 Stainless are used in environments up to 1600º F (850º C). 310 Stainless fasteners are used where temperatures may reach 2000º F (1100º C).
A .25% maximum carbon content is permissible in 310 Stainless. When carbon content is held under .08%, the material qualifies as 310S Stainless. In practice, most heat lots of 310 qualify as 310S.
