Haynes˘ 25 / L605

Haynes 25/L605 is a Cobalt-Nickel-Chromium-Tungsten alloy that combines good high temperature strength with good resistance to oxidising environments up to 980°C (1795°F) for long exposures. It also has excellent resistance to sulphidation, and responds extremely well to cold working. Known as the strongest of the formable Cobalt alloys, its widespread use has caused it to be investigated for use over a wide range of conditions, thus making it a well characterised material. Some of the industries Haynes 25/L605 is supplied to include aerospace, power generation, electronics, land-based turbines and medical. Haynes 25/L605 is also known as Udimet L605.

Hastelloy˘ C-2000

This alloy was developed to broaden the application range of one alloy. With the addition of Copper to the Nickel-Chromium-Molybdenum system, Hastelloy C-2000 is resistant to an extensive range of corrosive chemicals, including sulphuric, hydrochloric and hydrofluoric acids. The combination of Molybdenum and Copper provide excellent corrosion resistance to reducing media, while the high Chromium content gives good oxidising resistance. Like other nickel alloys, Hastelloy C-2000 is ductile, easy to form and weld, while possessing excellent resistance to stress corrosion cracking in chloride-bearing solutions.

Hastelloy˘ C-276

This Nickel-Molybdenum-Chromium alloy with the addition of Tungsten, has excellent corrosion resistance in a wide range of corrosive media and is especially resistant to pitting and crevice corrosion. Hastelloy C-276 is considered to be the most versatile corrosion resistant alloy available, as it is resistant to the formation of grain boundary precipitates in the weld heat-affected zone; this makes it ideal for most chemical process applications in an as welded condition. Hastelloy C-276 also has exceptional resistance to pitting, stress-corrosion cracking and oxidizing atmospheres, as well as excellent resistance to multiple different chemical environments. Hastelloy C-276 is also known as Nicrofer 5716, Superimphy 276, and Inconel C-276.

Hastelloy˘ C-22

A Nickel-Chromium-Molybdenum alloy with better overall resistance and versatility than any other NiCrMo available. It has excellent resistance to localised corrosion and to a variety of mixed industrial chemicals. Hastelloy C-22 is used in severely corrosive media involving high chloride and temperature applications such as buffer solutions, active pharmaceutical ingredients (API), fabric softeners, cleaning supplies, and condiments such as soy and chili sauce. Like other nickel alloys, Hastelloy C-22 is extremely ductile, exhibits exceptional weldability, and can easily be fabricated into industrial components. Hastelloy C-22 is also known as Nicrofer 5621, Superimphy C22, and Inconel 622.

Hastelloy˘ C-4

This Nickel-Chromium-Molybdenum alloy tolerates high temperatures and gives a design freedom in areas where weld geometry makes excessive heat build-up unavoidable. Resistance to general and localised corrosion and stress corrosion cracking is generally similar to Hastelloy C-276. With its high contents of Chromium and Molybdenum, Hastelloy C-4 is able to withstand both oxidizing and non-oxidizing acids, and is resistant to pitting and crevice attacks in the presence of chlorides and other halides. Like other nickel alloys, Hastelloy C-4 is ductile, easy to form and weld. Hastelloy C-4 is also known as Nicrofer 6616.

Hastelloy˘ B-3

This Nickel-Molybdenum alloy gives excellent resistance to hydrochloric acid at all concentrations and temperatures from ambient to high. It also withstands sulphuric, acetic, formic and phosphoric acids and other non-oxidizing media. B-3 also has excellent resistance to pitting corrosion and to stress-corrosion cracking. Hastelloy B-3 is not recommended in the presence of ferric or cupric salts. Like other nickel alloys, Hastelloy B-3 is ductile and can be formed and welded. It resists stress corrosion cracking in chloride-bearing solutions, and is able to withstand fluoride-bearing media and concentrated sulfuric acid, both of which result in damage to zirconium alloys.

Inconel® X750

Inconel® X750 is a Nickel-Chromium alloy made precipitation hardenable by additions of Aluminium and Titanium, having creep-rupture strength at high temperatures to about 700°C (1290°F). It is widely used for high temperature conditions but is not as strong as Nimonic 90, but Inconel® X750 also holds exceptional properties all the way down to cryogenic temperatures.

Incoloy® 800HT

This Nickel-Chromium-Iron alloy has the same basic composition as Incoloy 800, but has significantly higher creep rupture strength, resultant from the close control of the carbon, aluminium and titanium contents. It has good strength and excellent resistance to oxidation and carburisation in high temperature atmospheres. It also resists corrosion in many aqueous environments. Incoloy® 800HT is also known as Nicrofer 3220 HP.

Incoloy® 800

This Nickel-Iron-Chromium alloy has good strength and excellent resistance to oxidation and carburisation in high temperature atmospheres. Incoloy® 800 also resists corrosion in many aqueous environments, and has been used in some steam generation plants due to its resistance to stress cracking. Incoloy® 800 is also known as Nicrofer 3220, Nicrimphy 800, and Pyromet 800.

Inconel® 718

Nickel-Chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 700°C (1290°F). It has higher strength than Inconel® X-750 and better mechanical properties at lower temperatures than Nimonic 90 and Inconel® X-750. Inconel® 718 has exceptional weldability compared to the Nickel-base super alloys hardened by Aluminium and Titanium.

Nimonic® C-263

Nimonic® C-263 is an age-hardenable Nickel-Cobalt-Chromium-Molybdenum alloy designed for a combination of aged strength properties with exceptional fabrication characteristics. Nimonic® C-263 shows excellent intermediate temperature tensile ductility, and is typically used for applications such as aircraft turbine engine and land-based turbine applications. Nimonic® C-263 is also known as Nicrofer 5120 CoTi, Haynes 263, and Hastelloy C-263.

Nimonic® 90

A Nickel-Chromium-Cobalt alloy being precipitation hardenable, having high stress-rupture strength and creep resistance at high temperatures up to about 950°C (1740°F). It is widely used and a well proven alloy in high temperature conditions. Some typical applications for Nimonic® 90 include turbine blades, discs, forgings, ring sections, hot-working tools and other extreme environments. Nimonic® 90 is also known as Superimphy 90, Pyromet 90, and Udimet 90.
