Descripción
Características:
It is modified 309L austenitic stainless steel to higher silicon content to improve welding properties such as higher welding speed.
Aplicaciones:
It is used for oil and gas refineries, include welding of 22%Cr-12%Ni stainless steel, AISI 304L,316L in chemical and welding of dissimilar base metals of stainless and carbon steels.
Notas sobre el uso:
1. For TIG process, use DC(-) current, Argon Shield and Tungsten Electrode.
2. For MIG process, use Spray Transfer or Short Circuit Transfer mode.
3. 98%Argon – 2%O₂ shielding gas is recommended in MIG process.
