| Surface Engineering's Carboride
Hardfacing products are designed to resist severe abrasion in
combination with excellent corrosion resistance, adhesive wear
resistance, and high temperature resistance up to 1100º
Fahrenheit. The deposits contain up to 65% Fused Tungsten
Carbide in Nickel-Chrome-Silicon-Boron matrices ranging in
hardness from Rc18 to 62 for variances in toughness and impact
requirements. These self-fluxing alloys containing Boron
provide for high bond strengths between the Wc particles and
the matrix eliminating wear caused by the release of the hard
Wc particles upon impact. The composites provide for ease of
weldability and the deposits are smooth and uniform. Our
Carboride products may be appled by GTAW, SMAW, PTA,
Oxy-Acetylene, Spray & Fuse, Manual Torch, and our most
popular composition of 40% Nickel-Chrome-Boron and 60%
Tungsten Carbide is even available in the form of MIG wire.
Seaco Carboride product compositions are designated
by five (5) digit numbers, whereas the first two digits
indicate the percentage of matrix, the second
two indicate the percentage of Tungsten Carbide, and last
digit indicates the matrix hardness. Hence, Carboride 40606
would be a composition of 40% Rc 60 NiCrSiB and 60% Tungsten
Carbide. Compositions may be customized to suit individual
application requirements. Contact us for more information.
