API2HGr50 delivery status: steel is usually delivered in hot rolled or hot forged state. It can also be delivered in the state of heat treatment (annealing, normalizing or high temperature tempering). Annealing: The steel RINA grade D stern frame steel is heated to a suitable temperature and slowly cooled according to the heating time of different materials and specifications. Normalizing: Heat the steel plate to a suitable temperature and cool it in the air. Tempering: Keep the steel plate at an appropriate temperature for a long time while keeping it cool.
The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, RINA grade D stern frame steel, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.
