The ASTM E23 standard describes notched bar impact testing of metals according to Charpy and Izod.For the test, a notched metal specimen is broken in half using a pendulum hammer. The ASTM E23 standard describes the requirements for specimens, for the performance of the test, for result reports and for testing machines, i.e., pendulum impact testers at ambient . Finally, manganese contributes to low temperature impact toughness of the steel – its ability to withstand shock at cold temperatures-, which is critical for components used in freezing environments. . I rely greatly on the Brinell hardness test as a second basic metric for assessing the appropriateness of AISI 4140 alloy steel. It is a .In a Charpy impact test to ISO 148-1, a notched metal specimen is severed using a pendulum hammer. For the test, the metal specimen is centered on the supports in the pendulum impact tester. The notch is exactly across from the point at which the pendulum hammer strikes the specimen. This impact test is used to determine the absorbed impact energy.
It is preferred that welding be carried out on 4140 while in the annealed condition, and that the work piece, immediately on cooling to hand warm, is then stress relieved at 595 o C - 620 o C prior to hardening and tempering. Heat Treatment 4140-grade steel has 0.38 to 0.43% carbon and can be heat-treated to increase its hardness.
