  56. Slide 56: Welding and Fabrication of the HYBRID-BC1 Alloy

    Welding and Fabrication of the HYBRID-BC1 Alloy The weldability of this alloy is similar to that of C-276 alloy. To weld the C-type alloys, three processes are commonly used. For sheet welds and plate root passes, gas tungsten arc (GTAW) welding is favored. For plate welds, the gas metal arc (GMAW)

  57. Slide 57: Welding Guidelines

     The interpass temperature should be held below 93°C (200°F), and excessive heating should be avoided (especially on these parts).  The weld metal is viscous (sluggish), and therefore some torch manipulation is usually necessary. Increasing the current (amperage) will not substantially increase th

  59. Slide 59: Forming

    Forming HYBRID-BC1 alloy has excellent forming characteristics, and cold forming is the preferred method of shaping. The alloy can be easily cold worked due to its good ductility. The alloy is generally stiffer than the austenitic stainless steels; therefore, more energy is required during cold form
