ASTM A105 LF2 is a standard specification for forged carbon steel elements.

The steel is known for its excellent strength and toughness, which makes it suitable for use in high-pressure and high-temperature environments. Components may include flanges, fittings and valves. Our product possesses moderate strength and impact toughness with suitability to be heat treated, up to and including NPS 4.

  • Operates in high temperature environments
  • Moderate strength
  • Long service life
  • Good thermal insulation

A105 LF2 reliably operates under temperatures from 0° to 550°C. This class of steel lends itself well to hydro-carbon and marine engineering processes. It also finds use within nuclear power plants, oil and gas equipment, heat exchangers, pump manufacturing and petrochemical plants.

Forged carbon steel piping components are used for flanges, valves and fittings in pressure systems at higher temperatures and ambient service conditions. A105 LF2 flanges are a reliable and versatile choice for connecting pipes in various industrial applications, including oil and gas, chemical processing, power generation, and more.

Rust can occur with carbon steel. Oil varnishing provides lubrication. Anti-rust painting gives a protective layer, and electric zinc coating prevents the reach of water and oxygen. Both are viable methods for rust prevention.
