A537CL2 plate A537CL2 vessel plate

The A537Cl2 container plate is a large class of steel in

Container board with the composition and properties of special mainly be used forpressure vessel use, in use, temperature, corrosion of the different, container board material should be used, are not the same.

Heat treatment: hot rolling, controlled rolling, normalizing, normalizing + tempering,quenching tempering + (quenching and tempering)

Such as: Q345R, 16MnDR, 14Cr1MoR, 15CrMoR, 09MnNiDR, 12Cr2Mo1R, Q345R(HIC), 07MnCrMoVR, 13CrMo44,13MnNiMo54

Above is China brands, foreign brands are also many.

Such as: SA516Gr60, SA516Gr65, SA516Gr70, P355GH, P265GH and so on.

The main content of the new and old standards for control of boiler and pressure vessel steel plate

Container board Q345R delivery status description

Common delivery state are the following:

Quenching is heated to the temperature of phase transformation point: after theabove process, rapid cooling. To improve the hardness of the material, but decreases the toughness.

Normalizing: heating to above the phase transition temperature, normal cooling(air).

Annealing is heated to a temperature above the transformation point: after slow cooling. To eliminate the quenching effect, eliminate stress, uniform composition.

Tempering: after quenching, and then heated to a temperature (below thequenching temperature), insulation, and then cooling. Uniform in composition,slightly lower hardness, greatly improve the toughness.

In general: the first annealing, normalizing heat treatment to eliminate the effect ofthe original. And then quenching, tempering.
