P460Q Steel Quenching and Tempering: To remove some of the brittleness, you should temper the steel after quenching. Quenching and tempering provides the P460Q steel with high strength and ductility. Quenching and tempering is a heat-treatment method for high-quality heavy plates. Quenching and tempering consists of a two-stage heat-treatment process.
Stage 1 includes hardening, in which the P460Q plate is austenitized to approximately 900°C and then quickly cooled. The material is water-quenched in a quench unit, in which the plate is clamped to avoid warpage.
Stage 2 consists of tempering the P460Q steel to obtain the desired material properties. Quenching and tempering achieves an extremely fine-grained and homogeneous microstructure. Quenched and tempered steel is characterized by high strength and good ductility.
