Description
GENERAL CHARACTERISTICS:
Hardfacing alloy with a nickel base gives excellent resistance to severe abrasion, corrosion and galling. Astro HS-95 will retain its hardness in temperatures as high as 540C (1000F)
QUALITIES:
- Tensile Strength: Up to 200 Mpa (30,000 P.S.I.)
- Hardness: 57-60 R.C.
- Deposit: Magnetic
TYPICAL APPLICATIONS:
Recommended for use where metal to metal wear is involved; also for overlays subjected to severe abrasion and corrosion. Commonly used on valves, conveyors, cams, seal rings and cement pump screws. Astro HS-95 can be applied to carbon steels, alloyed steels and high chromium steels, cast iron, copper and nickel base alloys.
OXY WELDING PROCEDURES:
Clean the base metal.
A slight carburizing flame is recommended.
Heat a small area to a dull red heat, keeping the intermediate cone of the flame in contact with the base metal.
A technique similar to brazing should be used.
The deposit will spread evenly over the heated area; it should be smooth and not have ripples or craters on the surface.
Allow deposit to cool slowly, then grind to desired shape.
