NICKEL-CHROMIUM WHITE IRONS The oldest group of high-alloy ironsofindustrialimportance,the nickel-chromium white irons (Ni-Hard irons), have been produced for more than 50 years and are cost-effective materials for crushing and grinding. In these martensitic white irons, nickel is the primary alloying element, because3 to5%Niiseffectivein
Therefore, a new chromium oxide (Cr2O3) sapphire grinding wheel based on chemical mechanical grinding (CMG) principle has been developed and its performance has also been put into examination. The experiment result has demonstrated that Cr2O3 possesses an outstanding potential in terms of a high material removal rate of sapphire wafer, ...
The most important thing about grinding hard chrome is not to develop any heat. Use a grinding wheel with an open structure to make good cooling possible. Keep your grinding wheel sharp by dressing it more often than you normally would do. The grinding speed should preferably be about 35 mtrs/sec.
Chromium Plating Company has been providing the highest-quality Precision Grinding and chrome finishing solutions for the manufacturing industry for over 90 years.
Hexavalent chromium shows up in predominantly three forms: 1) Trivalent Chromium, which occurs naturally as chrome ore and is also an essential nutrient for proper metabolism; 2) Metallic or Elemental Chromium, typically found in aerospace alloys; and 3) Hexavalent Chromium, typically from industrial processes like welding and thermal spray.
Iron chromium grinding waste (ICGW) is an iron chromium solid waste, resulting from grinding processes of chromium steel. In China, N10 million tons of ICGW are produced each year. The solid waste is a mixture of small metal particles, lubricants, resin adhesive and residuals from grinding media, such as abrasive belts or stone wheels [23].
Thus, the aim of this paper is to study the performance of a grinding (or rough polishing) spherical flexible tool for obtaining cobalt-chromium prostheses on …
Chromium belongs to the category of difficult-to-machine materials that is applied by galvanic (electro-chemical) plating (chromium plating) and, therefore, it is processing by machining, in our case grinding, is current and the solution of these issues is demanded by industry, as they state e.g., [15,16].
Grinding of Powders The grinding of the chromium and the chromium carbide are both carried out in mills. There is always a risk of explosion when grinding fine metal powders and the mills are specially designed to deal with potential hazards such as this. Cryogenic cooling (liquid nitrogen) is also applied to the mill to facilitate grinding.
Abstract. Objectives: The aim of the study was to measure the dermal exposure levels of chromium dust during grinding of stainless and acid-proof steel parts.Methods: The potential dermal exposure of the body was measured with a patch sampling method and the actual exposure of hands with a hand-wash method. Simultaneously, personal air samples …

In dry grinding, the wear rate of high chromium cast irons is frequently ten times lower than cast or forged steel with a cost ratio of 2-3 times; economic justification is not difficult and explains the dominance of high chromium irons.
Chromium can be electroplated to a thickness of .050" and more. This provides many opportunities to salvage parts that have been machined under size and to repair worn parts. The Chromium Plating Company quality repair process will include precision grinding the worn part under size to remove all signs of wear.
