Iron alloys are most broadly divided by their carbon content: cast iron has 2–4% carbon impurities; wrought iron oxidizes away most of its carbon, to less than 0.1%. The much more valuable steel has a delicately intermediate carbon fraction, and its material properties range according to the carbon percentage: high carbon steel is stronger but more brittle than low carbon steel.
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.
A modern crucible used in the production of silicon ingots via the Czochralski process Smaller clay graphite crucibles for copper alloy melting. A crucible is a container in which metals or other substances may be melted or subjected to very high temperatures.
Crucible steel is steel that has been melted in a crucible rather than having been forged, with the result that it is more homogeneous. Most previous furnaces could not reach high enough temperatures to melt the steel. The early modern crucible steel industry resulted from the invention of Benjamin Huntsman in the 1740s. Blister steel (made as ...
Crucible steels like wootz steel and Damascus steel exhibit unique banding patterns because of the intermixed ferrite and cementite alloys in the steel.. Wootz steel is a crucible steel characterized by a pattern of bands and high carbon content.
Each thurible consists of a censer section, chains (typically three or four, although single-chain thuribles also exist), a metal ring around the chains (used to lock the lid of the censer section in place), and usually (although not always) a removable metal crucible in which the burning charcoals are placed. Many thuribles are supplied with a ...
Ulfberht swords were made during a period when European swords were still predominantly pattern welded ("false Damascus"), [7] [8] but with larger blooms of steel gradually becoming available, so that higher quality swords made after AD 1000 are increasingly likely to have crucible steel blades. The group of Ulfberht swords includes a wide ...
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).
