Materials

Specialty Steels

E-HV-975 - Smooth Kutt *see below

High-Tech Particle Metallurgy Specialty Steel featuring the highest wear resistance available in steel today. Its expectional wear resistance and combined moderate toughness offer the user increased productivity while reducing costly downtime and resharpening expenses. Excellent flex knife material.

E-HV-575

Particle Metallurgy Specialty Steel that offers users a unique combination of very high corrosion resistance and high wear resistance for applications that are exposed to corrosive and abrasive materials.

E-C-12

High Carbon High Chrome Specialty Steel with good wear resistance, low medium toughness and moderate corrosion resistance.

E-HV-900

Particle Metallurgy Specialty Steel possessing high-wear resistance combined with medium toughness. An excellent choice for applications requiring improved toughness over E-HV-975, E-LV-2 and E-HV-575 steels, especially anvils.

E-LV-2

High Speed Specialty Steel offering reasonably high wear resistance, low medium toughness and moderate costs. This combination makes it a choice for many applications.

E-C-5

High Carbon High Chrome Specialty Steel with high toughness and medium wear resistance properties but low corrosion resistance.

Submicron Carbide

E-WC-6

Submicron Tungsten/Colbalt Carbide with outstanding wear resistance but low toughness as compared to other carbide grades.

E-WC-15

Submicron Tungsten/Cobalt Carbide with very high wear resistance and excellent toughness.

E-WC-10

Submicron Tungsten/Cobalt Carbide with excellent wear resistance and moderate toughness

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 @ 500x

1. Smooth-Kutt E-HV-975 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.

Fine grain size
Even distribution
Superior cutting edge

Conventional HSS @ 500x

2. Conventional HSS microstructure shows a large array of irregular carbides unevenly distributed in the soft matrix. This creates severe micro-chipping that causes fibers to be only partially cut. This results in the material tearing instead of cutting evenly.

Larger grain size
Uneven distribution
Severe micro-chipping
