Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the S420ML steel yield strength project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of S420ML steel yield strength customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

Heat treatment advantages of S420ML steel yield strength, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
