The classification of tungsten steel is carried out according to
ISO standards. This classification is based on the material type of
the workpiece (eg P, M, K, N, S, H grades). The binder phase
composition mainly utilizes its strength and corrosion resistance.
The base of tungsten steel consists of two parts: one part is the
hardened phase; the other part is the bonding metal. The bonding
metal is generally an iron group metal, and cobalt and nickel are
commonly used. Therefore, there are tungsten-cobalt alloys,
tungsten-nickel alloys, and tungsten-titanium-cobalt alloys.
RX10 High hardness, suitable for roughing of iron, solid wood, dry
wood or nonferrous metal, ceramic and other alloys.
RX20 High toughness, easy to be brazed without heat preservation.
Suitable for rosewood, solid wood, pinewood, and other wood with a
lot stammer.
RX10T High hardness, suitable for finishing of iron, nonferrous
metal, ceramic and other alloying, semifinishing of of hardwood,
chipboard, MDF and HDF. Better to use silver soldering.
AB10 High toughness, difficult to break tooth. Special used for
finger jointing tool.
Advanced production equipment and unique manufacturing technology
to achieve stable quality and short delivery cycle.
Perfect process and ISO9001 quality certification system to ensure
product control lability and stability.
Adapt to market demands, develop new materials and optimize product
performance.
1. High hardness after quenching and tempering
2. Excellent wear resistance
3. Excellent hot-work performance
