Crucible Industries, commonly known as Crucible, is an American company which develops and manufactures specialty steels, and is the sole producer of a line of sintered steels known as Crucible Particle Metallurgy (CPM) steels.
CPM S30V is a martensitic (hardened) powder-made (sintered) wear and corrosion-resistant stainless steel developed by Dick Barber of Crucible Industries in collaboration with knifemaker Chris Reeve. [ 1 ] [ 2 ] Its chemistry promotes the formation and even distribution of vanadium carbides , which are harder and more resistant to abrasion than ...
Top steel producing companies. This is a list of the largest steel-producing companies in the world mostly based on the list by the World Steel Association.The list ranks steelmakers by volume of steel production in millions of tons over time and includes all steelmakers with production over 10 million in 2021.
154CM is a type of stainless steel developed and manufactured in the United States by Crucible Materials Corporation (now - Crucible Industries).Crucible 154CM is a modification of martensitic stainless steel type 440C to which molybdenum has been added.
Crucible Particle Metallurgy, a steel-making process developed by Crucible Industries; Cycle per minute, a unit similar to revolution per minute; Other uses
154CM [26] is produced by Crucible Industries. [13] It is used extensively by Benchmade Knife Company and many others. CPM 154 is identical to 154CM in composition, however it is produced by Crucible using CPM Process, [14] bringing all the benefits of Particle Metallurgy technology. [7] [27] ATS-34 is produced by Hitachi Metals. [28]
Crucible steel sequesters the raw input materials from the heat source, allowing precise control of carburization (raising) or decarburization (lowering carbon content). Fluxes, such as limestone, could be added to the crucible to remove or promote sulfur, silicon, and other impurities, further altering its material qualities.
Most historians who write about Crucible begin with the same founding events, but having Crucible in the name does not start until 1900. Then there is central site where Crucible has continuously produced steel, Syracuse. And there is the intellectual property. I decided to use them all to explain its history based the central-continuing location.
