BETHSTAR 80 steel plate is a high-strength product with an 80,000 psi minimum yield strength. It attains this strength in the as-rolled condition through the combination of a low-carbon microalloyed chemistry and controlled (proprietary) processing. It offers substantial cost savings when compared with quenched-and-tempered steel plate. BethStar 80 plate can be machined, formed and welded readily. It is used in several constructional applications and has the potential for many more applications. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-385. Producer or source: Bethlehem Steel Corporation.
