The safety performance of Astm a537 cl2 pressure vessel steel plate
- In the Astm a537 cl2 pressure vessel steel plate, the impact toughness of the Astm a537 cl2 pressure vessel steel plate is very good at normal temperature. However, once the temperature is lower than a certain critical value, the impact toughness of Astm a537 cl2 pressure vessel steel plate will suddenly drop, the fracture also no longer presents the fiber, but becomes crystalline, the fracture is also transformed from microporous to the crystal cleavage type.

In the Astm a537 cl2 pressure vessel steel plate, the impact toughness of the Astm a537 cl2 pressure vessel steel plate is very good at normal temperature. However, once the temperature is lower than a certain critical value, the impact toughness of Astm a537 cl2 pressure vessel steel plate will suddenly drop, the fracture also no longer presents the fiber, but becomes crystalline, the fracture is also transformed from microporous to the crystal cleavage type. With the temperature change, the Astm a537 cl2 pressure vessel steel plate yield strong. The degree of temperature changes, the temperature decreases, the yield strength increases, and the fracture strength does not change significantly, thus making the material embrittlement.
The ductile and brittle transition temperature of Astm a537 cl2 pressure vessel steel plate is not invariable, but changes with the change of external conditions. The brittleness transition temperature is affected by the thickness of Astm a537 cl2 pressure vessel steel plate, and the higher the thickness is, the higher the brittle transition temperature will be. it is not necessary to adopt low temperature steel in the process of manufacture. If the thickness of Astm a537 cl2 pressure vessel steel plate exceeds a particular temperature value, the brittle transition temperature will rise, which will bury the hidden danger for the safe operation of the product.
Through the research in this paper, the safety performance of Astm a537 cl2 pressure vessel steel plate can be greatly improved by ensuring that the ductile and brittle transition temperature of steel plate is not higher than the working temperature of Astm a537 cl2 pressure vessel steel plate . katalor is the supplier of Astm a537 cl2 pressure vessel steel plate，welcome to send your inquiry of Astm a537 cl2 pressure vessel steel plate.
