Question
Chromium in steel
Answer: Option A
Chromium in steel Increases strength, hardness, hardenability, and toughness, as well as creep resistance and strength at elevated temperatures.
It improves machinability and resistance to corrosion and it intensifies the effects of other alloying elements.
In hot-work steels and high speed steels, it increases red-hardness properties.
