It is present in many different compounds that have a variety of industrial applications, e.g. chromate pigments in dyes, paints, inks, and plastics; chromates added as anticorrosive agents to coatings, and chromic acid electroplated onto metal parts. Cr(VI) can also be formed when performing “hot work” such as welding on stainless steel, melting chromium metal, or ...

What is Hexavalent Chromium?Hexavalent chromium (Cr(VI)) compounds are a group of chemical substances that contain the metallic element chromium in its positive-6 valence (hexavalent) state. Generated anthropogenically, Cr(VI) readily penetrates biological membranes. ...
by:Brooks Applied Labs based inBothell, WASHINGTON (USA)
Chromium (Cr) is a polyvalent element and can exist in several distinct oxidation states, but only trivalent chromium [Cr(III)] and hexavalent chromium [Cr(VI)] occur with any frequency in the natural environment. The mobility, bioavailability, and toxicity of chromium largely depend on which of these two chemical species is ...
Manufactured by:ChartWater™ - A Chart Industries Company based inDuluth, GEORGIA (US) (USA)
Chromium exists naturally and commonly in two forms: trivalent chromium (Cr (III)) and hexavalent chromium (Cr (VI)). Cr (III) is used as a nutrition supplement since it is necessary to the human diet. On the other hand, Cr (VI) has been a cause of concern because of its level of ...

Painting: coating (epoxy powder) as protection against ...
Manufactured by:HENKEL Beiz- und Elektropoliertechnik GmbH & Co. KG based inWaidhofen/Thaya, GERMANY
Colouring stainless steel in conjunction with electropolishing. The HENKEL Interference Technique (HIT) uses the property of stainless steel to build up transparent layers of chromium oxides from sulphuric solutions of suitable composition and temperature on the surface. The passive layer is strengthened and characteristic colours are produced by interference effects of the ...

by:PRIMA Environmental, Inc. based inEl Dorado Hills, CALIFORNIA (USA)
PRIMA routinely evaluates potential secondary effects of in situ remediation technologies. The most common secondary effects of concern are oxidation of naturally occurring soil chromium to Cr(VI) during ISCO or mobilization of arsenic upon addition of a electron donor to stimulate anaerobic bioremediation. The magnitude, duration and significance of secondary effects is ...

Kuprofluorin impregnation – protecting woodKuprofluorin impregnation well penetrates into the wood with which a deeper protection of the wood is achieved. Kuprofluorin impregnation is water-soluble and does not contain chromium compounds. You can choose between two standard colour shades brown and green.We recommend Kuprofluorin impregnation mainly due to its long lasting ...
Manufactured by:Ningbo Hewcho Industrial Limited based inYuyao City, CHINA
Stainless steels, for example, are increasingly prone to build-up edge with increasing nickel content. Also important for the assessment of machinability is the chromium content. Stainless steels are divided into three main groups: austentia, ferritic / martensitic and duplex steels. The steels of the first two groups are significantly better to cut than the latter (see Figure ...

Manufactured by:HENKEL Beiz- und Elektropoliertechnik GmbH & Co. KG based inWaidhofen/Thaya, GERMANY
The corrosion resistance of stainless steel is based on the formation of a very thin chromium oxide-rich passive layer, which is formed only on metallically pure stainless steel surfaces. Scale layers, welding colours and tarnish, ferritic impurities (e.g. abrasion) and mechanical processing (e.g. grinding, blasting, etc.) inhibit the formation of a closed passive layer. ...
