H-12 hot work tool steel electrodes produce
chromium-tungsten-molybdenum weld deposits
that respond to hot work heat treatment
procedures. Weld deposit has excellent
resistance to chipping and heavy buildup
is possible when necessary. It is excellent for
repair of damaged tools and dies in the hot
work class, and repair of existing hot work
tooling where deposit must be annealed to
facilitate machining and rehardening.
