Examples from literature

• 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.
