S-7 shock resistant tool steel is completely
heat-treatable weld deposit that is both shock
resistant and dense. S-7 is well suited for
metal-to-metal wear areas and medium hot
and cold working units. S-7 is recommended
for welding AISI S-7 tool steel when
engineering changes, damaged areas,
or machining errors occur. The weld deposit
will, in fact, respond to a standard AISI S-7
harden and temper cycle. This product is
available in solid and tubular forms.
