The toughness of special steel can be assessed by specific tests and methodologies that evaluate its capacity to absorb energy and withstand fractures. One widely used approach is the Charpy V-Notch (CVN) test, in which a notched specimen is struck by a pendulum hammer, and the energy absorbed during fracture is measured. The results are then expressed as the energy absorbed per unit area, typically in joules per square centimeter (J/cm²) or foot-pounds per square inch (ft-lb/in²). Another commonly employed test is the Izod test, which is similar to the CVN test but involves a different specimen geometry. Furthermore, engineers and manufacturers may also employ other mechanical tests such as tensile strength, impact strength, and fracture toughness measurements to evaluate the toughness of special steel. These tests are invaluable in determining the suitability of special steel for various applications, particularly those requiring exceptional resistance to impact or sudden loading.

Additionally, other mechanical tests like tensile strength, impact strength, and fracture toughness measurements can also be used to assess the toughness of special steel. These tests help engineers and manufacturers determine the suitability of special steel for various applications, especially those that require high resistance to impact or sudden loading.
The toughness of special steel is typically measured using impact testing methods, such as the Charpy or Izod test. These tests involve measuring the amount of energy absorbed by the steel when it is struck by a pendulum or a falling weight. The higher the energy absorbed, the tougher the steel is considered to be.
