ASTM A568/A568M Grade 1074 Material Mechanical Properties
ASTM A568/A568M Grade 1074 is the American Society for Testing and Materials (ASTM) International standard for carbon steel, high-strength low-alloy (HSLA) steel for use in structural applications. It covers a variety of grades and product forms such as hot-rolled, cold-rolled, galvanized, aluminized, coated, and tempered steel. The standard provides requirements for chemical, mechanical and physical properties and defines five major groups of steel, each of which is further broken down into grades. Heat treatment is an important factor in achieving desired mechanical properties, and is often employed to enhance weldability.
