The container plate is a large class of steel plates -
container plates with special composition and properties. Mainly used for pressure vessels, for use, temperature, corrosion resistance of different, should be selected
container plate material is not the same.
Heat treatment: hot rolling, rolling, normalizing, normalizing + tempering, quenching + tempering (conditioning). Such as:
Q345R, 16MnDR, 14Cr1MoR, 15CrMoR, 09MnNiDR, 12Cr2Mo1R, Q345R, 07MnCrMoVR, 13CrMo44, 13MnNiMo54. (HIC) for more than Chinese brands, foreign brands are also many. Such as:
SA516Gr60, SA516Gr65, SA516Gr70, P355GH,
P265GH, and so on. The main contents of the new and old standards for steel plates used in boilers and pressure vessels are compared. The container plate widely used in petroleum, chemical industry, power plants, boilers and other industries, for the production of reactor, heat exchanger, separator, tank, oil tank, liquefied gas, nuclear reactor pressure vessel, boiler, liquefied petroleum gas cylinders, hydropower station high pressure pipes, turbine volute equipment and components.
The container plate Delivery status
Delivery status description for container board Q345R
The usual delivery status is as follows:
Quenching: a process of rapid cooling after heating to a temperature above the phase change point. Increase the hardness of the material, but reduce the toughness.
Normalization: normal cooling (air) after heating up to the phase change temperature.
Annealing: slow down after heating to a temperature above the phase change point. Eliminate quenching effect, eliminate stress, homogeneous composition.
Tempering: after quenching, then heated to a certain temperature (lower than the quenching temperature), heat preservation, and then cooling. Uniform composition, slightly reduce hardness, greatly improve toughness.
Generally speaking, annealing and normalizing are needed first, and the influence of primary heat treatment is eliminated. Then quench and then temper.
Specifically, controlled rolling is controlled rolling. It is based on adjusting the chemical composition of steel on the control of heating temperature, rolling temperature, deformation system parameters, variation control and transformation products of austenite microstructure, to refine the organization, improve the strength and toughness of the objective.
