Basic electrode for harfacing applications


SUPRADUR 400B is a thick basic-coated MMA electrode for depositing highly wear resisting hard facing deposits against sliding impacts. Surfacing of rails up to 1080/mm² Tensile Strength. Used for hard facing carbon steels and low alloy steels against sliding impacts. Weld metal hardness~ 375-450HB can only be machined by using sintered hard metal tools. Multi-layer deposits will be free of cracks, even without intermediate buffer layers. When welding crack sensitive base materials a buffer layer is required using more ductile C-Mn material or 307 type MMA electrode.


  • Weld metal hardness~ 375-450 HB can only be machined by using sintered hard metal tools.
  • Excellent weldability in all position except Vertical Down and Overhead positions.
  • Shall be used in DC+ or AC current

Welding Positions

  • All position, except vertical down
