A guide to technically superior INCONEL & INCOLOY alloys

Modern alloys have been developed over time using the latest technological knowledge to give them the properties needed for use in a range of essential industries. We look at some of the best in more detail

Alloys have been around for a long time, but as our knowledge of their properties and potential has improved over time, so too have the alloys themselves. Superior alloys are a precise blend of elements with careful treatment to ensure they can perform under some of the most extreme industrial conditions. The alloys that Corrotherm supplies are technically superior in many ways; we highlight four of the most advanced materials here.


This alloy is one of the most technically advanced materials that Corrotherm supplies, and it is a firm favourite of both our team members, as well as our customers. And for good reason… INCONEL alloy 625 has the most covetable blend of key properties, offering high strength, excellent fabricability and outstanding corrosion resistance. This means that it can lend itself to so many different industrial applications, including but not limited to the aerospace, automobile, oil extraction, oil refining, marine, waste treatment, pulp and paper, and power industries. You can read more about this alloy in our detailed product focus.


INCONEL alloy C-276 has been a popular alloy for decades and its use is not waning yet. It is known for its outstanding corrosion resistance to both acid and alkali media, making it exceptionally useful in very inhospitable environments. Not many alloys have properties like INCONEL alloy C-276, which is why its applications include chemical, pharmaceutical and food processing, pollution control, pulp and paper production, and the recovery of sour natural gas – all industries where materials have to hold up under extreme conditions. Find out more about this technical alloy, including its composition and properties in this blog.

INCOLOY 800H and 800HT

The INCOLOY 800 series of alloys has been specifically developed over time to meet the needs of the industries that it is utilised in as technical knowledge of alloy production has improved. The original INCOLOY alloy 800 was originally introduced in the Fifties to meet the need for a material that could be used in high-temperature and corrosive environments with a relatively low nickel content and low carbon element. Since then, it has been refined into two newer versions. INCOLOY alloy 800H has a more precise carbon content to offer higher creep and rupture properties for use in petrochemical processing and power generation. INCOLOY alloy 800HT is even more precise in its combination of elements and its treatment for very specific operating conditions. Find out more in our product focus looking at both of these advanced alloys.


Many modern alloys now make use of molybdenum within their makeup, which has a high melting point and therefore helps materials to stand up in high-temperature environments. INCOLOY alloy 825 offers both high strength and resistance to both reducing and oxidising media. It is considered the forerunner of molybdenum alloys, but it is still widely used, particularly in chemical processing for heat exchangers. It also plays a part in the oil and gas industry, and pollution control. While it’s known for its performance in high temperatures, it can also be used in cryogenic conditions, making it a versatile material. You can find out more in our product focus.
