Getig 904L, ER 385
AWS/SFA-5.9 ER 385 BS 2901-90 904S92
DIN 8556 WSGX2CrNiMoCuN 20.25
Solid wire which gives a “904L” type fully austenitic deposit. The wire gives a low carbon nil ferrite “super- austenitic” weld metal with good resistance to attack by a range of organic and inorganic acids, and better resistance to pitting attack than 317L type.
CHEMICAL ANALYSIS (RANGE) %
MECHANICAL PROPERTIES (RANGE)
