Nickel Alloy Products
Nickel will alloy readily with many other metals, including chromium, iron, molybdenum and copper. This allows for a wide variety of alloys that demonstrate outstanding resistance to corrosion and high-temperature scaling, exceptional high-temperature strength and other unique properties, such as shape memory and low coefficient of expansionNickel-Based Alloys for Extreme Environments
Nickel alloys are alloys consisting of nickel, with additional metals and chemicals, depending on what type of properties the alloy should have. The most common mix is nickel-chromium, but molybdenum, copper, and titanium are also frequently used in these types of alloys.
In general, nickel-based materials are known for their excellent corrosion and heat resistance while also maintaining outstanding strength. These properties make them ideal for use in high-temperature and high-chloride environments. However, there are also nickel alloys that are intended for cryogenic conditions (i.e. temperatures below -150° C).
The material’s many advantages makes it a popular choice for a variety of industries, including paper and pulp, oil and gas, aerospace, and chemical processing. Regardless of your needs, we at Specialty Steel Supply have the perfect nickel-based alloy for your project.
INCONEL® 625 Nickel Alloy
AMS 5581 | AMS 5599 | ASTM B443
Inconel® 625 nickel alloy with a chromium-nickel and low carbon content, is used for its outstanding corrosion resistance especially at elevated temperatures. This alloy has similar physical properties and fabrication characteristics as Type 304 at room temperature. The unique chemistry of Inconel® 625 increases the corrosion resistance in salt water applications and against high temperature oxidation. In the medical field, it has served the MRI compatible market due to its high nickel content that keeps a low magnetic permeability even at high strengths. Inconel® 625 is more expensive than 304, but is readily available.

INCONEL® 718 Nickel Alloy
UNS N07718 | ASTM B637 | AMS 5662 | AMS 5663
INCONEL® 718 is a nickel alloy. The material in the Annealed (per AMS 5662) condition can also be heat treated (per AMS5663), to increase strength and stress rupture (up to 1300°F), while maintaining good corrosion and heat resistance and weldability. 718 has is suitable for use in many environments and applications as it has good resistance to both alkaline and acid. 718 has good resistance to oxidation at temperatures seen in jet engine or gas turbines.

INCONEL® 718 NACE Nickel Alloy
UNS N07718 | ASTM B637 | NACE MR0175 | API 6ACR/718
INCONEL® 718 NACE is a variant of the 718 Nickel-based alloy. It is produced with a modified chemical composition and which has been age-hardened. It is produced specifically in a way to ensure it meets the maximum hardness requirements of NACE MR0175 for use in sour gas H₂S service. 718 NACE has good corrosion resistance and weldability, combined with high strength while having lighter tolerances on the hardness. Properties are typical and are not required to be reported in the Annealed condition. Typically, 440C is purchased in an annealed condition and then machined prior to heat treating as material can be hardened to 50-60HRC.

INCONEL® 725 Nickel Alloy
UNS N07725 | ASTM B805 | NACE MR0175
INCONEL® 725 nickel alloy 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 INCONEL® alloy 625, which is widely used in a broad range of severely corrosive environments. The strength of age-hardened INCONEL® alloy 725 is of the order of twice that of annealed alloy 625. Because the strength of alloy 725 is developed by heat treatment, not by cold work, ductility and toughness remain high. Also, strength can be imparted to large or non-uniform sections that cannot be strengthened by cold work.

INCOLOY® 825 Nickel Alloy
UNS N08825 | ASTM B423 | ASTM B424 | ASTM B425 | ASTM B564
Incoloy® 825 nickel alloy a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids.
Chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
INCOLOY® 925 Nickel Alloy
UNS N09925
Incoloy® 925 nickel alloy has excellent corrosion resistance consistent with Alloy 825. High levels of nickel ensure protection against stress corrosion cracking, whilst the additional molybdenum and copper resist reducing environments, in the same way that Chromium resists oxidising environments. Molybdenum enhances resistance to pitting and crevice corrosion, lifting the Pitting Resistance Equivalent number (PREN) to above 26. With such a balanced composition, Alloy 925 is particularly suited to down-hole applications in sour gas wells.
tubular products, valves, hangers, landing nipples, tool joints and packers. The alloy is also useful for fasteners, marine and pump shafting and high-strength piping systems
