USA knife straight blade BLACK
legendary fighting knife U.S. ARMY smooth black finish blade
(Epoxy-coated) Steel Blade: carbon 1095 (56-58HRC) handle of
layered, polished leather Blade Length: 13.3 cm total length: 23.5

1095: is high carbon steel, which is usually their knees in water
with a maximum hardness of 66 HRC to a shows good abrazivzdornost
and fracture toughness. Small steel hardenability this refers to
the production of thin metal blades. In terms of grain fracture is
steel according to ASTM 9 level. The values ??of mechanical
properties (ductility in torsion, Charpy tests on samples without
notch depending on the quenching temperature, deformation values
??depending on the voltage at different quenching temperature) are
available on the web. sites. Embrittlement, which occurs during
tempering temperature of about 260 ° C (final hardness is about 60
HRC) is a general problem of carbon and alloy steels with low
alloying addition. That the annealing temperature is consistently
avoid cutler! Since the tempering does not expected toughness at
lower temperatures and at higher results in too low strength turns
to processors for steels with lower carbon having improved
toughness at low temperatures, and tested bainite hardening. Most
manufacturers (Tramontina, Ontario, TOPS, Mora) recommends the use
of this material utmost care (due to the high hardness of the
blade) in the final grinding operation (there is his chipping) and
in thin preparations threatens lattice deformation. For these
reasons, it is recommended for smaller steel blade.
