ASTM A694 High Pressure Flanges

 Usually the high pressure flanges refer to forged flanges made from ASTM A694 materials for use in high-pressure transmission service. ASTM A694 forgings, known as high yield strength material, can be furnished in either carbon steel or alloy steel which are categorized into 9 grades: F42, F46, F48, F50, F52, F56, F60, F65 and F70. HBMetals has been engaged in several oil & gas projects supplying these high pressure piping components.
