Maximum hardenability of steel depends upon its_______________________?
Correct answer: A. Alloying elements content
- A. Alloying elements content
- B. Carbon content
- C. Grain size
- D. Chemical composition
Explanation
Alloying elements such as chromium, molybdenum, manganese and nickel delay transformation during cooling and therefore increase hardenability. Carbon affects hardenability too, but alloying-element content is the intended controlling factor for maximum hardenability here.
