HT-23
HT-23 is primarily used in joining tungsten carbides, tool steels, cast irons, stainless steels and nickel based heat resistant alloys. It provides high strength, good ductility, and short-term oxidation resistance above 1000°F (538°C).
Available Forms
Strip, engineered preforms, specialty preforms, powder and paste
Characteristics
HT-23 can be brazed by a variety of different processes including induction, vacuum, and atmospheric furnace brazing. When brazing under dry hydrogen or argon, ensure a dew point of at least -62°C. An atmospheric level of 10-3 torr or better is recommended for vacuum brazing. HT-23 also has excellent gap filling capabilities and develops maximum strength characteristics with clearances of 0.005-0.010”. It’s important to ensure that the base components are properly cleaned prior to the application of the braze alloy.
Properties
The properties of a braze joint are dependent upon the base metals, joint design and clearance, and brazing technique. *The mechanical properties listed above were determined from lap joints of tungsten carbide and SAE 4340 steel tested at ambient temperatures.
