TiC-based cermets may be successful in some applications, because of their favourable properties – low friction coefficient, fair weldability (owing to their expansion coefficient close to that of steels), remarkable resistance to oxidation, high specific strength and high [Read More]

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]
