Oxidation resistance of the TiC steel-cemented carbide was studied at 900,1000 and 1100 ℃ for 30,60,90 and 120 min, respectively; and potentiodynamic polarization curves of the cemented carbide in H 2 SO 4 solution,3. 5% NaCl solution and [Read More]

High-manganese steel liners, hammerheads, screen bars, sampans, etc. are the most widely used steel castings in cement plants. They are highly popular for their high wear resistance, good toughness and economy. Characteristics of high manganese steel: High manganese [Read More]

High manganese steel: High manganese steel is also called Hardfield steel. It is an excellent wear-resistant steel invented by Prof. R.A. Hadfield in 1883 and belongs to Fe-Mn-C austenitic manganese steel. The nominal high manganese steel has a [Read More]

Molybdenum: The main role of molybdenum is to refine the matrix, refine the carbides, increase the electrode potential of the matrix, and improve corrosion resistance. Because of the high price, plus no economy. In the metal casting conditions, [Read More]

Chromium: Chromium is a carbide forming element. Chromium is combined with carbon to form carbides, and the rest is dissolved in the matrix, thereby increasing the electrode potential of the matrix and resisting corrosion. If the content is [Read More]

Carbon: The wear resistance of high-manganese steel castings is not that the higher the carbon content is, the higher the wear resistance is, but there is a limit value. When the carbon content is higher than 1.4%, many [Read More]

TM:60 High-manganese steel base alloy, with high hardness and good wear resistance, obvious work hardening, can be cast or arc welding, non-magnetic, but can not be machined, hardness is lower than TM52, but the impact toughness ratio TM52 [Read More]

TM52: High manganese steel base alloy with high hardness and good wear resistance, obvious work hardening, can be cast or arc welding, non-magnetic, but can not be machined, suitable for the production of rock tools, hammer head Alloys [Read More]

Steel-bonded cemented carbide combines the respective characteristics of steel and cemented carbide to form its own unique comprehensive performance advantage. This excellent overall performance makes it in the mold and mold materials, wear-resistant and shock-absorbing parts, high temperature [Read More]

As the name implies, steel-bonded carbide is a composite material prepared by powder metallurgy with steel as the binder phase and refractory metal carbides (mainly carbonized titanium and tungsten carbide) as the hard phase. Between steel and cemented [Read More]
