US-36/AF-490AS is a solid wire/flux combination for welding mild steels as well as HT490 class steels. AF-490AS, a fluoride-basic agglomerated flux, shows superb and stable notch toughness down to -40°C as well as good usability in combination with US-36 SAW wire. Details related to US-36 x AF-490E are shown in Table 8.
3-1. Properties of all weld bl
The chemistries and mechanical properties of the all weld bl are shown in Tables 9 and 10, respectively. Impact test results in the as-welded condition as well as after Postweld Heat Treatment (PWHT) are shown in Figures 9 and 10 by the transition curves, respectively.
Designed for optimum flux basicity, AF-490AS can obtain stable and excellent notch toughness at temperatures as low as -40°C even though no special elements have been added. The bead appearance is shown in Figure 11.
