ASTM A516/A516M A516 Grade70( A516Gr70) Steel plate for pressure vessels is a high quality material designed for use in extreme pressure and temperature environments. It is a steel that meets the strict standards of the American Society for Materials and Testing (ASTM) for pressure vessels, boilers and other high-temperature and high-pressure equipment.

 

1.Chemical Composition

 

ASTM A516/A516M A516 Grade70( A516Gr70) The chemical composition of steel plates for pressure vessels includes elements such as manganese, phosphorus, sulfur, silicon and carbon. These elements are present in steel in specific proportions to guarantee its excellent mechanical properties and durability. Manganese is one of the most important components, the content is usually between 0.4% and 0.9%. It gives the steel its outstanding tensile strength and ductility(%):

C < 0.30, Si < 0.60, Mn 0.80-1.20, P < 0.025, S < 0.015, Ni < 0.30, Cr < 0.30, Cu < 0.30, Mo < 0.08.

 

 

2.Mechanical Properties

 

ASTM A516/A516M A516 Grade70( A516Gr70) Steel plates for pressure vessels have excellent mechanical properties and are suitable for a variety of demanding applications. Its high tensile strength, yield strength and impact resistance ensure that its performance is maintained under extreme operating conditions. In addition, the steel has good fatigue strength and is suitable for applications where cyclic loads are required.

 

3.Heat Treatment State

 

ASTM A516/A516M A516 Grade70( A516Gr70) Steel plates for pressure vessels are usually heat-treated to obtain the desired mechanical properties. The heat treatment process involves heating the steel to a high temperature, holding it for a period of time, and then rapidly cooling it to room temperature. This process improves the mechanical properties of the steel and increases its durability.

 

4. Low Temperature Impact Test

 

ASTM A516/A516M A516 Grade70( A516Gr70) Steel plates for pressure vessels undergo low temperature shock tests to evaluate their performance in low temperature environments. The impact test can test the fracture resistance of steel under sudden impact at low temperature. This test ensures that the steel can maintain its mechanical properties at low temperatures.

 

5. Main Application Scenarios

 

ASTM A516/A516M A516 Grade70( A516Gr70) Steel plates for pressure vessels are mainly used in the manufacture of pressure vessels, boilers and other high temperature and high pressure equipment. This steel is widely used in the power industry to make boiler components such as headers, water walls and economizers. In addition, it is used to manufacture pressure vessels for a variety of industries, including chemical, oil and gas, and pulp and paper production.
