ASTM A572 covers low-alloy, high-strength steels of four different yield strength levels, 42, 50, 60 and 65 ksi. Strengthening is provided by small additions of columbium, vanadium, columbium+vanadium or vanadium+nitrogen. Maximum carbon is at 0.21 to 0.26%, depending on thickness, as shown in the tabulation under composition. This datasheet provides information on composition and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-448. Producer or source: Alloy steel mills and foundries.

Mittal Steel T-Star is a high-strength low-alloy (HSLA) multipurpose structural grade with reliable performance in cold weather. This datasheet provides information on composition and tensile properties as well as fracture toughness. It also includes information on low temperature performance as well as forming. Filing Code: SA-578. Producer or source: Mittal Steel USA Flat Products.

BETHLEHEM V-STAR 50 is an as-rolled steel for and H-and sheet piling sections. It offers the design benefits of high-strength steel economically. It is particularly good where impact loading is encountered. It is readily weldable using conventional welding processes. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on joining. Filing Code: SA-438. Producer or source: Bethlehem Steel Corporation.

Cromax is a long, hard-chrome plated product in the form of bars and tubes. These products are available in different steel grades with executions in a broad range of sizes. This datasheet provides information on composition, hardness, and tensile properties. It also includes information on corrosion resistance and surface qualities as well as forming, machining, and joining. Filing Code: SA-740. Producer or source: Ovako Cromax AB.
