CARBON STEEL FLANGE
The most common material grade in use today is A105 forged carbon steel, with sizes ranging from 1/2“ – 24” in ASME B16.5, 26” – 60” in ASME B16.47, and 26” – 96” in B16.1 (for temperatures ranging from ambient up to 1,000 Fahrenheit and pressure between 20 – 6,170 psi). The wide temperature and pressure range makes carbon steel flanges an attractive solution for several industrial applications, and have proven to be one of the least expensive pricing options.
Modern carbon is a common steel with carbon content up to 2.1% by weight and primarily alloyed with iron. The term “carbon steel” may also be used to call out steel which does not have a large amount of chromium or nickel. The carbon content can vary for A105 with a maximum allowable of 0.35 as a percentage composition. As the carbon content increases, the steel hardens and increases in strength through heat treatment processes. Many common treatment techniques in the industry are quenching, tempering, and normalizing. As carbon steel is treated, it become less ductile and brittle. This makes it slightly more difficult to shape and weld, however the trade off in field service is often considered worth the extra effort to form the necessary weld seals.
For trace elements, no alloy element (minimum content) is required, specifically in reference to molybdenum, nickel, chromium, titanium, and vanadium.
Low Temperature (Low Temp) Carbon Steel Flanges
A350 LF1, LF2 and LF3 are low temp carbon steel flanges, commonly available in the market.
They are suitable for use down to –20ºF for LF1 flange, –50ºF for an LF2 flange and -150ºF for an LF3 flange.
The most common low temperature flange is A350 LF2 flange. LF2 is very similar to A105 flange but is tested to charpy V-Notch test at -50F for toughness.
350 LF2 is a carbon steel fitting material, very similar to A105, that is used in general industrial applications and can withstand continuous service down to -46F. This material is supplied in a normalized condition and then Charpy V-Notch tested at -50F.
Most often the term used for "low temp flange" means A350 LF2 flange, unless otherwise specified.
High Yield Carbon Steel Flange
ASTM specification A694 covers the carbon and alloy steel forging for flanges, fittings and other high pressure transmission applications. This spec covers material used in high pressure wellheads, pressure piping and equipment manifolds.
High yield A694 flanges are available in F42, F46, F48, F50, F52, F56, F60, F65, F70. The last two digits implies the yield strength in Ksi. For example an F50 flange will have a yield strength of 50 ksi compared to 36 ksi yield of a regular A105 flange. The high yield strength is critical in high pressure and high temperature applications.
Chrome Moly Alloy Flange (Chrome Flange)
A182 / SA182 specification covers forged low alloy and stainless steel flanges, valves and fittings.
Chrom moly is an abbreviation of Chromium Molybdenum Steel. It is has high tensile strength and malleability, along with good weldability. Chrome flanges are less corrosion resistant that regular stainless steel flange but offer higher tensile strength and weight to strength ratio.
Most common chrome flanges are F5, F9, F11 class 2 (CL2) and F22 class 3 (CL3)

OTHER CARBON STEEL FLANGES
We also offer variants of carbon steel flanges which would traditionally be made in ASTM A105.
Options made from plate include A515-70, A516-70,and both in the normalized condition. These are typically used to make line blank style flanges per ASME B16.48. In addition, we have A36 plate and A285 Grade C plate when the superior overall properties of 515/516 are less of a concern. You will often find A36 plate steel used for smaller waterworks type flanges, as well as custom ring and disc flanges made for one-off applications.
If your application calls for low temperature service, consider A350 LF2 forged carbon flanges (with Charpy V-Notch Impact Tests at -50°F) or the superior LF3 (CVNs at -150°F). These are very similar to A105 in most ways, but are rated for colder ambient utilization.
