GB/T 17854-2018 S F308L FB-S308L NB/T 47018-2017 |
Features and Applications：
1. An alkaline agglomerated flux specially designed for stainless steels and heat-resistant steels.
2.When paired with welding wires such as HOCr21Ni10, H00Cr21Ni10, and H00Cr19Ni12Mo2, it is used for welding stainless steels and high-alloy heat-resistant steels.
3.It is widely used in petrochemical industries, liquefied air pressure vessels and piping, corrosion-resistant overlay welding of clad plates, as well as the welding of pressure valves, offshore platforms, and subsea pipelines.

Precautions:
1. The flux shall be dried at 300–350 °C for 2 hours before use.
2.Prior to welding, impurities such as rust, primer, oil, grease, carbon-arc gouging scale, and welding slag shall be removed from the base metal surface.
3.The flux may be reused, however, at least 20% new flux shall be added each time to maintain the welding process performance and the mechanical properties of the weld metal.
