ASTM A105 Flanges are forged flanges that are manufactured using ASTM A105 carbon steel, which is a standard specification for carbon steel forgings for piping applications. ASTM A105 is a widely used specification that covers carbon steel forgings for various high-temperature and pressure applications, including flanges, fittings, valves, and other components used in pipelines.
ASTM A350 LF2 is a specification that covers several grades of low alloy and carbon steel forgings intended for use in low-temperature service. A350 LF2 is commonly used in applications where impact toughness is a critical requirement, especially in environments where temperatures can drop to extremely low levels.
ASTM A350 LF2 Flanges, therefore, refer to flanges made from ASTM A350 LF2 steel. A350 LF2 is a low carbon steel with additional elements such as manganese, silicon, nickel, chromium, molybdenum, and copper, depending on the specific grade within the A350 LF2 specification.
ASTM A694 is a specification that covers carbon and alloy steel forgings for pipe flanges, fittings, valves, and other components used in high-pressure transmission service. Within the ASTM A694 specification, there are several grades, and one of them is ASTM A694 F65, which is a high-yield carbon steel grade. Flanges made from this material are often referred to as Carbon Steel High Yield ASTM A694 Flanges.
The "high yield" designation in ASTM A694 F65 indicates that the material has enhanced yield strength compared to standard carbon steels.
A694 F42 Flange: This grade typically has a minimum yield strength of 42,000 psi (290 MPa). It's used in applications where moderate strength and toughness are required.
A694 F46 Flange: F46 has a minimum yield strength of 46,000 psi (315 MPa). It is selected for applications where increased strength compared to F42 is necessary.
A694 F52 Flange: F52 offers a higher minimum yield strength of 52,000 psi (360 MPa). It's suitable for applications demanding increased strength and resilience.
A694 F60 Flange: F60 has a minimum yield strength of 60,000 psi (415 MPa). It's chosen for applications requiring even higher strength and resistance to harsh conditions.
A694 F65 Flange: F65 provides a minimum yield strength of 65,000 psi (450 MPa). It is used in applications with high-pressure and high-temperature requirements.
A694 F70 Flange: F70 exhibits a minimum yield strength of 70,000 psi (485 MPa). It is one of the highest-strength grades, suitable for extremely demanding environments.
