Abstract:The paper describes the production process and properties of NVD(E) 420 high strength hull plate,studies the composition-quenching microstructure and properties of steel plate,investigates the effect of process parameters on mechanical properties by introducing rational low content value design and combining the site production experience.Thus rational process parameters are found out and good actual product properties are obtained,which provides the technological reserve for the development of higher grade and larger thickness hull plate.
Keywords:Quenching and tempering  Hardenability  Strength and toughness properties  Mechanical properties
