Having
covered steel classification and
the effects of alloying elements
in steel, it seems logical to present information
about the composition of various steels used by knifemakers.
The table below shows the percentage of each significant
element present in each steel listed. The elements
are listed with their mnemonic designation in the periodic
table of elements as follows:
- C - Carbon
- Mn- Manganese
- Si- Silicon
- Cr- Chromium
- Ni- Nickel
- Mo- Molybdenum
- V - Vanadium
- W - Tungsten
The percentages are approximate and sometimes show a range such as
.95 - 1.03 because no two batches of steel are exactly alike. If you
receive a certificate of analysis with your shipment of steel, the
results may vary from those listed here. Elements considered by knifemakers
to be impurities such as sulphur and phosphorous have been omitted.
Analysis could also show traces of copper, niobium, titanium, zirconium,
cerium, boron, lead, aluminum, calcium, nitrogen, hydrogen, arsenic,
antimony, and cobalt.
