What is steel bonded carbide? What are its characteristics?
Good physical and mechanical properties of steel bonded carbide in a hardened state has very high Hardness. Because it contains a lot of dispersed high hardness of hard phase, the wear resistance can be close to the high cobalt hard alloy. Compared with high alloy die steel, has high elastic modulus, wear resistance, compressive strength and flexural strength. Compared with the hard alloy, with good toughness. It has good chemical stability and self lubrication resistance, low friction coefficient and excellent.
Steel bonded hard alloy is a kind of material between steel and hard alloy, has the following characteristics: good technological properties with processing and heat treatment, under the annealed state, can be used in machining, car equipment and tool milling, planing, milling, drilling and other mechanical processing. Also, forging welding. Compared with hard alloy, low cost, wide application range.
Steel bonded carbide in steel bonding, with carbide (mainly titanium carbide, tungsten carbide) do hard phase composite material manufactured by powder metallurgy method. The microstructure is fine hard phase dispersed evenly distributed in the steel matrix (for steel bonded hard alloy mould substrate is mainly used chromium, molybdenum and vanadium in high carbon alloy tool steel or high speed steel).
