HSLA Steel Plates

A572: A572 is a high strength low alloy steel plate used in a variety of structural applications. It is produced in Grades 42, 50, 60 & 65- the grades representing the yield strength.
A588 / A606 / A242: A588 is a high-strength low-alloy steel plate used in structural applications such as bridges and buildings. Its advantage over A572 50 is its weathering ability, which provides atmospheric corrosion resistance and ultimately longer life in applications where exposure to elements will be a factor.
CSA G40.21 44W
CSA G40.21 50W / 50A: The Common grades are G40.21 50W and G40.21 50A. 50A has higher alloy content than 50W which contributes to its weathering ability. Both 50W and 50A are sometimes referred to with their metric designations of 350W and 350A. When referenced with a T, such as50WT, this indicates that charpy tests are required. When Charpy tests are required, the category will be indicated.
A656: A high strength low alloy steel plate used in structural applications where lighter weight and improved formability is critical. Made to Grades 50, 60, 70 and 80- the grade designating the yield point
