Is ASTM A694 F60 Good Quality for High-Pressure Applications?
Yes, ASTM A694 F60 is a high-yield grade that is specifically designed to be used in the high-pressure pipeline transmission service where high-pressure and high-toughness are essential in a service. The F60 designation implies minimum yield strength of 60 ksi (415 MPa), 67 times greater than standard A105 (36 ksi), 43 times greater than F42 (42 ksi), and 15 times greater than F52 (52 ksi), giving the design a significant design headroom in high pressure operations and a design of pipeline that is optimally designed with a reduced wall thickness.
A694 F60 is manufactured to align with API 5L X60 line pipe that is commonly applied in high pressure transmission pipeline where the high mechanical properties are essential. The specification requires production of fully-deoxidized steel, hot forging to form complete wrought structure, and regulated heat treatment, usually normalizing and tempering or quenching and tempering. This treatment guarantees the fine grained micro structure with high combination of strength, toughness and ductility.
Microalloying elements found in the material usually include niobium (Nb), vanadium (V) and titanium (Ti) that offer sequestration of grains and precipitation of stronger metals, leading to improved mechanical properties without a lot of carbon contents. This is a controlled method of chemistry, which is well weldable (carbon equivalent is usually =0.45-0.47) yet gives high levels of strength. F60 applications are often stipulated to be impact tested to guarantee sufficient toughness of notches to serve pipelines.
F60 is also used in high-pressure offshore pipelines, deepwater, high-pressure gathering system, critical wellhead manifold, and transmission lines with high-pressure, where the supplementary strength is important to offer better safety factors and reliability. Although more costly than F42 or F52, high mechanical properties are worth the extra price when the application is critical and the effects of failure are very high. Even greater strength levels may be used, such as F65 grade, but F60 is the best compromise in most high pressure pipeline work.

Frequently Asked Questions (FAQ)
F60 has a greater yield strength (60 ksi as compared to 52 ksi which is about 15 per cent higher) and greater tensile strength span (75-95 ksi as compared to 66-85 ksi). F60 usually contains a lot of carbon and manganese with increased microalloying (Nb, V, Ti). F60 needs at least 590-C of tempering compared to F52 of 540-C. F60 is an equivalent of API 5L X60 pipeline in greater pressure pipes.
F60 minimum 590-C (1100-F) tempering vs 540-C (1000-F) F42/F52 to provide sufficient toughness at higher strengths. An increase in the temperature of tempering assists in alleviating any residual stresses, hardens martensite in case it is a result of quenching and that it has an appropriate microstructure to achieve the best combination of strength and toughness.
Impact testing is not required following the ASTM A694 base specification but usually purchased by customers in F60 applications because of increased levels of strength. The very common one is Charpy V-notch testing at 0-C or design minimum temperature, minimum 27-40 J average depending upon application sensitivity and codes.
Yes, and with due specification and qualification. In case of H2S service according to NACE MR0175/ ISO 15156, stipulate HIC testing as to NACE TM0284, SSC resistance testing, maximum of 22 HRC hardness 248 HB, product analysis, limited carbon equivalent, and sour service documentation. Stronger F60 needs even closer sour service qualification than F42/F52.
Niobium (Nb), vanadium (V) and titanium (Ti) are added in low concentrations (0.02-0.10%) to give grain refining and precipitation hardening. They are able to produce high strength (60 ksi yield) without too much carbon content, and are good to weld. These components create fine carbides/nitride which increase the strength of the steel.
F60 is much stronger in yield (60 ksi vs 38 ksi, about 58 higher) but equal tensile strength (75-95 ksi vs 70-90 ksi). F60 is used with high-pressure pipeline transmission of API 5L X60 pipeline of required heat treatment; A516 Gr 70 pipe is used with pressure vessels.
