Hexavalent Chromium

Welding, grinding and sanding materials that are coated with chromium can create hexavalent chromium fumes. Some of these materials include stainless steel, carbon steel with high carbon content and galvanized steel. Hexavalent chromium fumes must be filtered at the source, before they can be inhaled by workers. Serious Health Effects

Hexavalent chromium in welding fumes

Chromium metal is used in many steel alloys to harden the material and make it more resistant to corrosion. Chromium metal itself is not very dangerous, but during welding or grinding the metal is oxidized to hazardous hexavalent chromium. This substance is also used in certain paints and coatings for its corrosion protection.

Surface finishing

We perform centerless grinding together with hard chrome, or as an independent working process. Focusing on component roughness and finish. Centerless grinding is a machining process where we remove material from a component by means of grinding stones and a brake roller.

At Electronic Chrome & Grinding Co. we have specialty deep plating tanks for commercial applications to suit your deep tank chrome plating needs. Hard chromium plating is chrome plating that has been applied as a fairly heavy coating (usually measured in thouhs of an inch) for wear resistance, lubricity, oil retention and other wear resistant purposes....

Stainless/ Hexavalent Chromium Exposure at Work

 · I had no idea up until 5 minutes ago how stainless steel welding/cutting/grinding would expose me to hexavalent chromium. The warehouse I work in has absolutely no ventilation, other than the bay doors being open. I've been around that stuff for at least a week straight, plasma cutting, grinding, and a whole lot of welding with no respirator.

What is the Effect of Chromium on Wet Grinding

2019-10-3 · Table of ContentsElectrochemical measurementsLaboratory flotation testsResultsDiscussion Because of higher efficiency, wet grinding is more widely used than dry grinding, but leads to an increased consumption of grinding media due to corrosion in some ores. 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

Grinding problem for chrome part?

 · Well, Metals Handbook Vol. 2, 8th edn. (1964) pre-dates CBN usage, and since chrome has an HRC of ~57, the newer Desk Edition would seem to recommend CBN. Conventional wisdom for many years has been that because chromium plating is brittle and contains high residual stresses, aggressive cutting media and heat build-up must be avoided.
