Stainless steel 310S questions
Direct answers for engineers, buyers and fabricators reviewing 310S.
What is stainless steel 310S? +
310S is a low-carbon version of type 310: a high-chromium, high-nickel austenitic stainless steel developed for elevated-temperature oxidation resistance.
Is 310S magnetic? +
It is generally non-magnetic in the solution-annealed condition. Cold working or fabrication can create a slight magnetic response.
What is the UNS number for 310S? +
The UNS designation is S31008. The commonly used European material number is EN 1.4845.
What temperature can 310S withstand? +
Manufacturer data commonly cites service up to about 1050°C (1922°F) in dry air. Cycling, contaminants, mechanical load and atmosphere can reduce the practical limit.
Can 310S be welded? +
Yes. Use procedures and filler metals appropriate to high-alloy austenitic stainless steels and the intended service.
How should 310S be specified? +
State the grade, product form, governing standard, dimensions, tolerances, condition, finish, inspection and certification requirements.
