Question

Steel is heated to a very high temperature and then plunged into cold water. This process is called tempering.

• A. True
• B. False

Answer 1

The correct option is A True

Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal.

This is usually done by heating the material at a very high temperature and then plunging into the cold water.
