Carbon Steel Flanges

The most commonly used material grade today is A105 forged carbon steel in 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 to 1,000 degrees Fahrenheit and pressures ranging from 20 – 6,170 psi). The wide range of temperatures and pressures makes carbon steel flanges an attractive solution for a variety of industrial applications and has proven to be one of the least expensive options.

Modern carbon steel is a common steel with a carbon content of up to 2.1% by weight, alloyed primarily with iron. The term “carbon steel” can also be used to refer to steel that does not contain significant amounts of chromium or nickel. the carbon content of A105 steel can vary, with a maximum allowable carbon content of 0.35. as the carbon content increases, the steel hardens and is treated with a heat treatment process to increase its strength. Many common treatment techniques used in the industry include hardening, tempering and normalizing. When carbon steel is treated, it becomes less tough and brittle. This makes it slightly more difficult to form and weld, but in field service it is usually considered worth the extra effort to form the necessary welds.
