AS-4

Super Tensile strength ,excellent weldability.

Alloy Base

Fe, Cr, Ni, Mn

Special Features

  • Used for economic, reliable, speedy and high quality welds.
  • A versatile welding alloy for unknown steel.
  • High tensile strength, with tough weld deposits.
  • Used for machinable build-up.

    • Recommendations

    It is used for similar and dissimilar steels, Superior weld ability for die steels, leaf steels, and tool steels. AS-4 is recommended for high strength joints in high carbon steel, alloy steel, austenitic steels. Used when resistance to corrosion is needed.

    Principal Applications

    Cushion layer, spring shafts, dissimilar unknown steels, machinable build-up on gear pinions, build-up on steel castings, tool steels, springs etc.

    Procedure

    Clean weld joints and gauge out cracked joints & fatigued material. Staggered & skip sequence is needed for good welding. To weld heavy sections, preheat required otherwise preheat is not necessary
