Thermal conductivity is same as austenitic and lower than carbon steel. This means it takes longer to reach the correct interpass temperature.See all results for this questionWelding of Austenitic Stainless Steel - Part 2 - TWIWelding consumables must also be selected with low carbon content if best corrosion resistance is required. Most arc welding consumables contain less than 0.03% carbon but there are filler metals available with carbon contents of up to 0.10%; these should only be used to weld the 'H' grades of steel where good creep resistance is required.
