Alloy 718 (UNS N07718) is a high-strength, corrosion-resistant nickel chromium material that offers high strength and excellent corrosion resistance, particularly in H2S and CO2 environments.  For applications requiring higher yield strength, consider our BOHLER L718 API-150ksi, which offers a minimum yield strength of 150 ksi. 718 can be used in high temperatures as it has high temp de-rating factors and maintains strength at elevated temperatures.  Several conditions of 718 API are available at vSM. We offer the NACE/API 6ACRA versions at 120 ksi min yield as well as the 150 ksi high strength version.  Both tempers are suitable for sour service and can be used for pressure containing and pressure controlling equipment in corrosive environments. Typical applications include packers, safety valves, pumps, hangers, connectors, and fasteners.

Alloy 725 (UNS N07725), commonly known as Inconel 725, is a nickel chromium-molybdenum-niobium alloy that is highly resistant to corrosion and is age hardenable for extremely high strength. It has essentially the same corrosion resistance as Alloy 625, which is widely used in a broad range of severely corrosive environments in the oil & gas sector. The strength of age-hardened Alloy 725 is of the order of twice that of annealed Alloy 625. Alloy 725 exhibits a high resistance in reducing and oxidizing environments and increased resistance to pitting and crevice corrosion in sea water and stress corrosion cracking.  Because the strength of alloy 725 is developed by heat treatment, not by cold work, ductility and toughness remain high. The properties of Alloy 725 are useful for a range of applications that require outstanding corrosion resistance along with high strength. The alloy is used for hangers, landing nipples, side pocket mandrels and polished bore receptacles in sour gas service, where it resists the effects of hydrogen sulfide, chlorides and carbon dioxide. The alloy is also attractive for high strength fasteners in marine applications, where it resists corrosion, pitting and crevice attack in sea water. For applications with moderate strength requirements, explore our Alloy 925. Material Designations Market Grade UNS Alloy 725 N07725   Standards ASTM OTHERS OTHERS B805 NACE MR0175 API 6ACRA

Alloy 925 (UNS N09925), commonly known as Incoloy 925, is an age-hardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum. Alloy 925 is used in numerous applications requiring a combination of high strength and corrosion resistance.  For applications requiring higher strength, explore our Alloy 725, which offers superior mechanical properties and corrosion resistance. The nickel, in conjunction with molybdenum and copper, provides excellent resistance to reducing chemicals and its chromium content renders protection in oxidizing environments.  Because of its resistance to sulfide stress cracking and stress-corrosion cracking in sour crude oil and natural gas, it is used for down-hole and surface gas well components including but not limited to: packers, pump shafts in marine environments, safety valves, hangers, landing nipples and fasteners.

F6NM is a stainless soft martensitic Cr steel with 4% nickel with molybdenum addition and medium corrosion resistance in media with only a low chloride content. To achieve the best possible corrosion resistance with F6NM, it is essential to polish the surfaces concerned. Good mechanical properties in the quenched and tempered condition. This makes this material very suitable for use in turbine and power plant construction. Very good low-temperature properties. Recommended temperature of use: – 60 to 350°C. Use for valves, pumps, compressors, centrifuges, hydroelectric machines, turbines, reactor technology, shipbuilding, chemicals. Special heat treatment to max. 23 HRC is required for sour gas environments in petroleum engineering.
