UNS S31000 AISI 310 Stainless steel

This data sheet applies to stainless steel 310 / 1.4845 hot and cold rolled sheet, strip and bars, semi-finished products, rods and sections as well as for seamless and welded steel tubes for mechanical and general engineering purposes.

Application

For construction parts which should be resistant to scaling up to about 1050°C and extensively inured to the effect of sulfurous gases, especially above 900°C, is very low.
