ASTM A572 steel plate is a popular high-strength low alloy (HSLA) steel commonly used in structural applications. A572 steel contains chemical alloys that enhance the material's hardness and ability to bear weight, and the material is lighter than steels with similar compositions.
A572 steel plate is available in five different grades: Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65. Each grade has slightly different mechanical properties and chemical composition, which may make them more suitable for certain applications. However, the A572-50 is the most common A572 class.
