At present, material workers in China and around the world have invested a great deal of enthusiasm and energy in the main battlefield of this technological progress. The elements that have been used in the alloying of high [Read More]

high manganese steel ： magnetic or not

04/27/2018 langfeng Uncategorized

Q: Must the magnets hold high manganese steel? A: Not necessarily. Only austenite has a non-magnetic character. High-manganese steel is a typical austenitic steel, so it is not magnetic. However, austenitic steels are not only high-manganese steels, but [Read More]

High manganese steel wear parts

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 in wear-resistant materials

04/27/2018 langfeng tic based cermet

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 in wear-resistant materials

04/27/2018 langfeng tic based cermet

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]

Silicon in wear-resistant materials

04/27/2018 langfeng Uncategorized

Silicon: High silicon content reduces the solubility of carbon in austenite, carbides precipitate at the grain boundaries and increases in size. After water toughening, large microscopic porosity is left at grain boundaries, but in order to completely eliminate [Read More]

Carbon element in wear-resistant materials

04/27/2018 langfeng tic based cermet

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]
