ASTM A723 Technical Regulation: High-Strength Forged Products
The ASTM A723 standard establishes stringent requirements for the production of alloy steel forgings that have undergone heat treatment via quenching and tempering. This product range is supplied by EV Group China for heavy engineering needs, including the design of pressure vessels, isostatic pressing system components, and specialized shock-wave equipment.
An important limitation of the standard is the prohibition of using these steel grades in welded metal structures due to specific requirements regarding the metal’s structure and operational performance.
Steel Classification and Physical-Mechanical Properties
The specification covers three grades of nickel-chromium-molybdenum steels, divided into six classes based on tensile strength levels. The selection of a specific grade and class is determined by engineering calculations, taking into account the forging geometry and design loads.
EV Group China ensures the supply of rolled metal products in full compliance with international standards. When preparing technical documentation, it should be noted that values in the metric system and the SI system (indicated in parentheses) are not direct equivalents. To avoid errors during design, it is recommended to use the single system of measurement specified in the project documentation.
