Exaton 22.12.HTR
22.12.HTR is a covered electrode with rutile-acid coating and about 110% metal recovery. It gives a chromium-nickel weld metal that is scaling resistant in air up to 1150°C (2102°F). Spray transfer gives a bead with a finely rippled surface. There is little spatter and very good slag removal. 22.12.HTR is intended primarily for welding the high temperature steels 253MA (1) UNS S30815. It is also suitable for welding other high temperature steels, such as AISI 309 and EN 1.4828. (1): 253MA is a trademark owned by Outokumpu Stainless.
