Characteristics and welding directions
AVESTA 904L is intended for welding
Outokumpu 904L and similar but can also be
used for constructions in type ASTM 316
where a ferrite-free weld metal is required,
such as cryogenic or non-magnetic
applications. The impact strength at low
temperature is excellent.
A fully austenitic structure is more prone to
hot or solidification cracking than type ASTM
316 welds, so welding should be performed
minimising the heat input, interpass
temperature and penetration with parent
metal.
Welding is best performed using a pulsed
arc power source.
