BÖHLER L718API

BÖHLER L718 API (UNS N07718) is a high-strength, corrosion-resistant nickel chromium iron molybdenum material that offers high strength and excellent corrosion resistance, particularly in H2S and CO2 environments. It is a precipitation hardenable alloy, the precipitation hardening effect is mainly achieved by additions of Niobium, Titanium and Aluminium. The ease and economy with which BÖHLER L718 API can be fabricated, combined with good tensile, fatigue, creep, and rupture strength, have resulted in its use in a wide range of applications. It have been widely recognised by the oil industry and it is now widely used in this field. BÖHLER L718 API offers outstanding weldability with resistance to post-weld cracking. It can be used in high temperatures as it maintains strength at elevated temperatures. Several conditions of BÖHLER L718 API are available and it is offered to the NACE/API 6A CRA versions at 120 /140 ksi min yield as well as the 150 ksi high strength version. All tempers are suitable for sour service and can be used for pressure containing and pressure controlling equipment in corrosive environments. Typical applications include packers, pumps, connectors, and fasteners as well as gate valves, choke stems, tubing hangers and fire safe valves but also multiple downhole drilling & completions, nuclear and surface applications.
