The pointed deleterious effect of the chromate
quenching on the performance of the duplex systems is not a consequence of the presence of a chromate
layer by itself.
Certain particulate hexavalent chromium [Cr(VI)] compounds are well-documented human respiratory carcinogens that release genotoxic soluble chromate
and are associated with fibrosis, fibrosarcomas, adenocarcinomas, and squamous cell carcinomas of the lung.
Industrial uses of hexavalent chromium compounds include chromate
pigments in dyes, paints, inks, and plastics; chromates
added as anticorrosive agents to paints, primers, and other surface coatings; and chromic acid electroplated onto metal parts to provide a decorative or protective coating.
In addition G&W provides controlled shot peening, media blasting, chromate
conversion coatings and other surface preparations.
He said that Iran currently ranked 17th in terms of copper production and 8th in terms of barite and chromate
Based on these studies, we propose a mechanism for chromate
carcinogenesis that is primarily driven by the genomic instability paradigm.

The guards were from a private Afghan security company and were hired by the government to secure a chromate
mine in the province's Spera district, provincial spokesman Khaibar Pashtun told Pajhwok Afghan News.
Workers in the 5th Maintenance Squadron identified several areas that were endangering their workers: Strontium Chromate
levels that were 80 times above AFOSH standards; airborne particles that were 50 percent above occupational exposure limits; no sprinkler heads in exhausting ducts which could encourage fire proliferation throughout A/C dock; and inability to check airflow to know when dangerous conditions existed.
On the bolt style, the fixing nut is bright chromate
