AUTOTHERME GRADE-347
AWS: SFA 5.9 ER347
EN ISO CODE: 14343-B SS347
Autotherme Gr. 347 continuous, solid corrosion-resistant, chromium nickel wire for welding austenitic chromium nickel alloys of the 18% Cr-8% Ni type. Autotherme Grade-347 has good general corrosion resistance. The alloy is stabilized with niobium to improve resistance to the Intergranular corrosion of the weld metal. Due to the niobium content, this alloy is recommended for use at higher temperatures. This wire can be used in combination with Maxflux SS-4.
