In 2009, Crucible Steel introduced an update to CPM-S30V to meet the needs of renowned knife maker Chris Reeve that they called CPM-S35VN. The addition of 0.5% Niobium, and reductions in both Carbon (from 1.45% to 1.40%) and Vanadium (from 4% to 3%) produced an alloy with 25% increase in measured Charpy V-notch toughness over S30V (Crucible claims 15-20% improvement).
The SxxV series are Crucible Industries [13] stainless steels produced using CPM process. [14] CPM S30V, [35] on the lower end of the SxxV steels, it has a carbon content of 1.45%. However, S30V is still considered to be a superior choice for knife making. CPM S30V is used in a wide range of commercial knives.
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 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.
By the 1870s, the firm, then trading under the easier name of Morgan Crucible, was said to be the largest manufacturer of crucibles in the world. [7] In 1890, Morgan Crucible became a company; it was no longer a family concern although the shares remained in the hands of directors and senior executives, and it remained so until 1946. By 1900 ...
