High strength GB/T 11251 35CrMnSiA steel plates for

GB/T 11251 35CrMnSiA steel plates are widely used to manufacture medium speed, heavy load, high strength, high toughness parts and high strength components. BBN steel has been engaged in GB/T 11251 35CrMnSiA steel plates since 2000, and always try to offer more added value to our clients. Modeling and Composition Design of Low-Alloy Steels The quenching sample range is [850, 1100]. In the quenching stage, in order to make the steel fully austenitized, the lowest temperature is selected to be 850 °C. If the quenching temperature is too high, it will cause overburning of the quenched steel, causing the steel to easily crack and brittle.
