Alloy steels are classified using AISI four-digit numbers and include various types of steel that contain higher levels of elements such as manganese (Mn), carbon (C), molybdenum (Mo), silicon (Si), nickel (Ni), vanadium (V), and boron (B) than those permitted in carbon steels. These alloys offer enhanced responsiveness to mechanical and heat treatments compared to standard carbon steels.
These datasheets provide a detailed overview of ASTM A514 Grade B alloy steel plate, known for its high yield strength and excellent performance in demanding applications.
