Basicity Index (according to Boniszewski) is 0.6. Particle size is 0.4 – 1.4mm. Nominal composition of the flux is: 50%(SiO2) + 30%(CaO+MgO+MnO+K2O) + 12%(CaF2) + 8%(Al2O3). Specifications BS EN 760 S A CS 2 ASME IX Qualification QW432 F-No -, QW442 A-No -. Materials to be welded ASTM-ASME BS DIN UNS N04400 NA13 2.4360 UNS N04405 NA1 (cast) 2.4361 UNS N05500 2.4365 (cast) A494 M-35-1 (cast) A494 M-35-2 (cast) Proprietary Monel alloy 400, R405, K500 (Special Metals) Nicorros (VDM) Applications For welding alloy 400 and similar parent material to itself and to others in the Ni-Cu alloy system, such as pure nickel and cupronickel. Welds in alloy K500 are satisfactory, but cannot match the strength of this precipitation-hardened alloy. Castings of alloy 400 with up to about 1.5%Si are welded with Nimrod 190, but higher silicon grades such as BS3071 NA2 and ASTM A743 M35-2 are virtually unweldable because of HAZ cracking. For dissimilar joints between alloy 400 and other alloys or steels, sensitivity to dilution by Fe (20-30%) or Cr (3- 6%) can lead to low ductility (or bend-test fissuring) in weld metal close to the fusion boundary. Direct welds to mild or low alloy steels are satisfactory with dilution control, although ERNiCr-3 wire is preferable and necessary for stainless and higher chromium alloys (see data sheets D-10 and D-11). Alternatively, the steel or alloy can be buttered with pure nickel (see data sheet D- 50) and this procedure is also useful when surfacing with alloy 400 consumables. Alloy 400 has a useful combination of strength, thermal conductivity and resistance to corrosion by seawater, inorganic salts, sulphuric and hydrofluoric acids, hydrogen fluoride and alkalis. Applications include heat exchangers, piping, vessels and evaporators in the offshore, marine, chemical, petrochemical and power engineering industries. Microstructure Solid solution, single phase alloy, slightly ferromagnetic near room temperature. Welding guidelines No preheat required, maximum interpass temperature 150?C and no PWHT required.

Packaging data Metrode NiCu flux is supplied in sealed moisture resistant 20kg metal drums. Storage Preferred storage conditions for open drums:<60%rh,>18°C. If flux has become damp or has been stored for a long period, it should be redried in the range 300-400°C for 1- 2 hours. Fume data SAW fume is negligible.
