Kennametal Stellite Nucalloy® 41 Nickel-Chromium-Boron Alloy
Categories:	Metal; Nonferrous Metal; Nickel Alloy; Superalloy
Material Notes:	Stood® 41 is a nickel-chromium-boron alloy. Stood 41 can be certified to meet MIL-N-24422 (ships) Composition A. Stood 41 derives its superior wear resistance from the presence of hard nickel borides - and to a lesser extent, chromium carbides - tightly held in a tough nickel-rich matrix. It is machinable with carbide tools and may be cast centrifugally or as a static casting. Information provided by Deloro Stellite Inc. Deloro Stellite uses both the names Nucalloy® 41 and Stood® 41 for this alloy. Product of former Deloro Stellite Inc.
Key Words:	MIL-N-24422; Deloro Stellite Inc.
