Abstract: A heat treating process for homogenizing high nickel alloy material so that the carbon is stabilized in the form of carbides having chromium-sufficient "envelopes". A heavily coldworked intermediate sized tube is annealed by a continuous conveyor furnace for about 20 minutes at a temperature of about 1350.degree. F. The stabilized product is then cold worked to final size and annealed at a temperature about 1485.degree. F., without the occurrence of sensitization and the associated susceptibility to corrosion attack. The final product has extremely fine grain size and the carbides are distributed throughout the grains. The method is also suitable for use on other austenitic alloys.

Abstract: A knife for shearing hot metal at temperatures between about 1400.degree. F. and 2400.degree. F. and particularly between about 1800.degree. F. and 2200.degree. F. Typically, the knife is used for shearing blooms or strands produced by continuous casting into billets at like high temperatures. The knife is composite including a base of alloy tool steel, specifically AISI 4130 and a cutting edge of a high-temperature-resistant alloy, specifically INCONEL Alloy 718. These alloys are weld compatible and are joined into a mechanically sturdy unit by an electron-beam fusion weld, carried out in an evacuated atmosphere substantially free of oxygen to preclude reaction of oxygen with the alloy components such as Ti having a high affinity for oxygen.
