Voorbeelden van chromium

• Prolonged heating and high temperatures have a very bad effect upon chromium steels. 

• The combined action of tungsten and chromium in steel gives to it the remarkable property of maintaining its cutting edge at relatively high temperature. 

• The following table shows the percentages of carbon, manganese, nickel, chromium and vanadium in typical steel alloys for engineering purposes. 

• The nickel intensifies the physical characteristics of the chromium and the chromium has a similar effect on the nickel. 

• When chromium is alloyed with tungsten, a very definite red-hardness is noticed with a great increase of cutting efficiency. 

• Elemental analyses of this deteriorated wood showed high levels of copper, chromium, iron, and lead, suggesting that a caustic chemical spill had occurred.

• Results were obtained for arsenic, cadmium, chromium, cobalt, copper, lead, nickel, and zinc.

• Chromium supplementation in growing goats indicated that the kids were responding normally to this stress.

• The same procedure was adopted to compute the combined pollution load from hides and skins for 2004 and for chromium for both years.

• The heavy metals in the ash included arsenic, cadmium, chromium, manganese, nickel, cobalt, copper, zinc, and lead.

• Chromium supplementation does not influence glucose metabolism or insulin action in response to cold exposure in mature sheep.

• The test was performed after 135 days of chromium supplementation.

• There were burns that contained wood that did not have high arsenic, chromium, and copper readings (burns 11, 12, 14, 15, and 19).

• Influence of chromium tripicolinate on glucose metabolism and nutrient partitioning in growing lambs.

• High concentrations of chromium and lead are associated with this caustic chemical spill.

• For the surface coated with fish extract there was also a significant decrease in the chromium signal.

• The most commonly used metals are titanium, cobalt, chromium, molybdenum alloy and steel.

• As a result, these soils contain high concentrations of oxidized transition metal minerals, particularly chromium and manganese, as well as perchlorate.

• The highest readings of arsenic, chromium, and copper all occurred when wood was present.

• Further correlations existed between heavy metals in the ash for: arsenic and chromium; and arsenic and manganese.
