Easy-flo™ Stainless Steel Grade Flux Paste is a brazing flux suitable for use with silver brazing filler metals. It has a working range of 550-775°C and can be used with silver brazing filler metals melting below 725°C. It is suitable for use on all the common engineering materials, (copper, bass, mild steel and stainless steel), but not aluminum. JM special purpose fluxes are required when brazing aluminum bronze, certain grades of stainless steel, tungsten, molybdenum and tungsten carbide or where protracted heating is involved. Easy-flo™ Stainless Steel Grade flux has an increased fluoride content giving improved fluxing on stainless steel, but as a result may also be more prone to exhaustion.
