Strenx Section 650 is a cold-formed steel section made of hot-rolled, high-strength steel with a minimum yield strength of 650 MPa (94 ksi). Its high strength combined with naturally stiff form enables construction of stronger and lighter structures. The common shape is a U-bend channel. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on forming, machining, and joining.
