Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome , or is said to have been chromed .
Recent revisions of ASTM B633 defer to ASTM F1941 for zinc plating mechanical fasteners, like bolts, nuts, etc. 2019 is the current revision for ASTM B633 (superseded the revision from 2015), which raised required tensile thresholds when confronting hydrogen embrittlement issues and addressed embrittlement concerns in a new appendix.
In 1995, Erie Plating Company was titled "Manufacturing Business of the Year" by Gannon University. [12] Erie Plating Company received the City of Erie Pennsylvania's Environmental Award for Waste Treatment in 1999, and an additional 12-month continuous compliance award in 2000. [13]
SRG Global's Advanced Development Center opened in May 2010 in Taylor, a suburb of Detroit. The 46,000-square-foot (4,300 m 2) facility houses a chrome plating line and four injection molding presses ranging from 165 to 2,200 tons to create parts for coating and testing in the center’s on-site laboratories. The Advanced Development Center is ...
Final treatment of iron and steel products before onward sale into manufacturing includes pickling in strong mineral acid to remove rust and prepare the surface for tin or chromium plating or for other surface treatments such as galvanisation or painting. The two acids commonly used are hydrochloric acid and sulfuric acid. Wastewater include ...

School bus painted in Chrome yellow [7] Approximately 136,000 tonnes (150,000 tons) of hexavalent chromium , mainly sodium dichromate, were produced in 1985. [ 8 ] Chromates and dichromates are used in chrome plating to protect metals from corrosion and to improve paint adhesion.
Attempts have been made to test the removal or reduction of hexavalent chromium from aqueous solutions. [22] Another study done by the American Industrial Hygiene Association indicates that the airborne hexavalent chromium in acidic mists of an electroplating tank collected on PVC filters was reduced over time after mist generation.
