Compliance Audits: Ensuring that supplied materials meet the specific tolerances and testing protocols required by contract. This standard is a critical specification in the

Delivery Condition: Specifically applies to plates in the quenched and tempered (Q+T) state, which provides a balance of high strength and good toughness . Quenching: The steel is heated above its austenitizing

1. Quenching: The steel is heated above its austenitizing temperature and rapidly cooled (usually in water). This transforms the microstructure into martensite or bainite, maximizing hardness and strength.
2. Tempering: The steel is reheated to a temperature below the critical point (Ac1) and held for a specific time. This relieves internal stresses induced by quenching and improves ductility and toughness at the expense of a slight reduction in hardness.
