CastoTig 45654 W

CastoWig 45654 W

The austenitic weld metal is work-hardening, cold-tough down to -196 °C and temper-resistant up to 650 °C. High creep rupture strength up to 950 °C. Resistant to wet corrosion in media containing chlorine as well as in acidic, neutral and alkaline aqueous solutions, e.g: Sulphuric, hydrochloric, nitric, phosphoric and hydrofluoric acid, seawater, caustic soda and cooling brine. Scale-resistant up to 1200 °C in a sulphur-free atmosphere and max. 500 °C in a sulphurous atmosphere. Permissible operating temperature from -196 °C to +550 °C.

as well as for mixed joints of these materials and unalloyed and low-alloy steels, e.g:
P 235 GH, P 265 GH, P 295 GH, P 355 N, 16 Mo 3
and for joints of cold-tough Ni steels, such as
1.5662 - X 8 Ni 9.

Processing instructions
Clean welding areas. Adjust the heat input during welding to the component, its material and dimensions. Limit the interpass temperature to 150 °C. Ensure continuous filler metal feed. Form sufficiently for root welds. Use wire brushes made of austenitic CrNi steels.
