U.S.NAVY straight knife blade BLACK
legendary fighting knife U.S. Navy smooth, blackened blade
(Epoxy-coated) kind of steel: carbon 1095 (56-58HRC) stainless
steel handle of layered, polished leather Blade Length: 17.8 cm
total length: 30.2 cm Weight: 306 g comes in a leather case with
logo U.S. NAVY Steel 1095: is high carbon steel, which is usually
their knees in water with a maximum hardness up to 66 HRC, and has
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.
