Smooth-Kutt™
(E-HV-975)
This new High-Tech PM specialty steel
has the highest wear resistance available
in steel today. Its exceptional wear
resistance and combined moderate
toughness offer the user increased
productivity while reducing costly
downtime and resharpening expenses.
Knife costs are somewhat higher,
but the extended life makes it
very cost-effective.

Microstructure
& Cutting Edge
Comparison
Images 1 and 2 illustrate white particles that are primary
hard carbides and black areas that are the softer matrix.
SMOOTH-KUTT™ microstructure shows well rounded,
evenly distributed carbides within a very fine grain size.
These characteristics create a cutting edge that continues to give
a smooth cut to fibers even after the edge starts to wear.
CONVENTIONAL HSS microstructure shows a large array of
irregular carbides unevenly distributed in the soft matrix.
This creates severe micro-chipping that
cause fibers to be only partially cut.
This results in the material tearing
instead of cutting evenly.

Specialty Steels
This new High-Tech PM specialty steel
has high-wear resistance combined with
medium toughness. It is an excellent
choice for for applications requiring
improved toughness over E-HV-975,
E-LV-2 and E-HV-575 steels.
|
 |
This new High-Tech PM specialty steel
offers the user a unique combination of
very high corrosion resistance and high
wear resistance for those applications
that are exposed to corrosive yet
abrasive materials.
|
 |
This standard high speed specialty steel
offers the user reasonably high wear
resistance, low medium toughness and
moderate costs, making it a choice for
many applications.
|
 |
This high carbon, high chrome
specialty steel has good wear
resistance, low medium
toughness and moderate
corrosion resisting properties. |
| |
 |
Submicron Carbide
This submicron tungsten/cobalt carbide
has outstanding wear resistance but
low toughness as compared to other
carbide grades.
|
|
|
This submicron tungsten/cobalt carbide
has excellent wear resistance and
moderate toughness as compared
to other carbide grades.
|
 |
This submicron tungsten/cobalt
carbide has very high wear resistance
and excellent toughness as compared
to other carbide grades. |
| |
 |
Ceramics
The mechanical strength of YZ-110HS
approaches typical tungsten carbide
values and are much higher than those
of sintered alumina or silicon nitride.
The absence of a metal phase greatly
improves corrosion wear rate over
various grades of tungsten carbide.
Norzide Zirconia TZP has excellent
resistance to abrasive corrosion and
is most suitable for circular knives
and blades especially where complex,
dual phase wear conditions exist.

Heat Treat
We use local facilities that are equipped with the latest technology
available today in heat treating.
This allows us quick delivery
while maintaining the quality that
you expect. Vacuum HT, Salt Bath HT,
Cryogenics and Black Oxide are just a
few of the services we provide.
Please contact Everwear for more
detailed information regarding the
thermal treatments, hardening data
and surface treatments of a
specific material.
|
 |
This treatment offers the best surface
protection but usually requires longer
process cycles. Vacuum promotes
more uniform cooling which helps
control distorsion. A vacuum is used
instead of the more commonly used
protective gas atmospheres.
During quenching, the chamber is
backfilled up to or above atmospheric
pressure with an inert gas, which is
circulated by an internal fan.
This allows fast even cooling of
the knife and consistent hardness
throughout the knife structure.
|
 |
Salt Bath treatment offers the quickest
and most uniform heating. The stirring
action of electrodes suspended in the
Salt Bath produces an even temperature
throughout the bath. It is regarded as
one of the most stable heat treat methods
available. However, it is sometimes limited
in size and quantities.
|
 |
What is cryogenics (300° below)? Super cryogenic treatment
of metal is a relatively new process.
A dry process means that the
material is not exposed to any Cyrogenic
liquids which eliminates the risk of
thermal shock. The material is frozen
through a thermal-dynamic refrigeration cycle.
This process can improve a material that is
unstable during heat treat and give added
benefit by enhancing that material's true
potential for wear resistance and toughness. |

Coatings
Titanium Nitride coatings are used in
applications demanding high wear with
minimum interference or impact.
They work well also with various bagger
blades due to the added wear resistance
and excellent release properties.
|
 |
Teflon is a coating used mainly where
impact does not exist. It has the highest
release capabilities but very little impact
resistance. This coating has also been
used with selected types of bagger blades.
|
 |
Electroless Nickel is a chemical reduction
process that deposits a hard nonporous
and highly corrosion resistant coating
on a wide variety of materials without
the use of electrolytic deposition.
With the absence of a current, nickel
is plated to a precisely controlled
thickness on all surfaces and coating
is deposited evenly without edge buildup
regardless of the configuration of the part
being plated. This allows us to maintain
a sharp edge. The most important property
of electroless nickel is its superior
ability to protect knives from corrosion
and preserve knife edges before use.
|
 |
Chrome Plating is used mainly for coating
rolls which can increase roll life.
A higher finish can also be obtained
for applications needing a smoother finish. |
