SS ER310 Filler Wire has useful oxidation and scaling resistance up to 1200 degrees C and good cryogenic toughness down to -196 degrees C. The main applications for ER310 Welding Wire are at elevated temperatures for example in furnaces. Unlike other standards 300 series stainless steel weld metals the 310 weld metal is fully austenitic and finds some applications where its low magnetic permeability proves useful e.g. drilling instrumentation.
