Impact test requirement for carbon steel
The impact energy of low-strength metals that do not show a change of fracture mode with temperature, is usually high and insensitive to temperature. For these reasons, impact tests are not widely used for assessing the fracture-resistance of low-strength materials whose fracture modes remain unchanged with temperature. Impact tests typically show a ductile-brittle transition for low-strength materials that do exhibit change in fracture mode with temperature such as bod… Witryna17 lut 2024 · Introduction Fabrication of pressure vessels or parts with carbon or low alloy steel for cryogenic applications, may require impact testing. ...
