ASTM Standard Seamless Tube Impact Test

The impact toughness of ASTM standard seamless tube reflects the resistance of the metal to the external impact load. It is generally expressed by the impact toughness value (ak) and the impact energy (Ak), whose units are J/cm2 and J (joules) respectively. Impact toughness or impact energy test (referred to as “impact test”) is divided into three types: normal…
