FeCrAl heating alloy

Iron-chromium-aluminum alloy (FeCrAl) is a high-performance iron-based electric heating material with high resistivity, low temperature coefficient of resistance, high operating temperature, and excellent oxidation and corrosion resistance in high-temperature environments. This material is widely used in chemical industry, metallurgy and high-temperature heating equipment to provide durable and stable heating solutions. Heating elements made of iron-chromium-aluminum alloy help optimize energy efficiency and reduce industrial production costs.

0Cr27Al7Mo2

0Cr27Al7Mo2 (Russian brand number Х27Ю7М2) is a ferritic iron-chromium-aluminum-molybdenum special alloy. By adding 2% molybdenum (Mo), the material has extremely high creep resistance and mechanical stability at high temperatures. With a maximum continuous operating temperature of up to 1400°C, it is the material of choice for industrial high-temperature furnaces, laboratory equipment and extremely demanding heating elements.

Frequently Asked Questions (FAQ)

Why can 0Cr27Al7Mo2 reach 1400℃? What does molybdenum do?

0Cr27Al7Mo2 (Russian standard Х27Ю7М2) strengthens the matrix by adding about 2% molybdenum. It still has strong creep resistance and mechanical stability at a high temperature of 1400°C, and the components are not easy to deform and sag. It is the first choice material for industrial high-temperature furnaces, laboratory equipment and extremely demanding heating elements. It is also the grade with the highest temperature range in the iron-chromium-aluminum group.

What are the melting point, resistivity and density of 0Cr27Al7Mo2?

How to distinguish the temperature resistance levels of 0Cr27Al7Mo2 and 0Cr21Al6Nb?

What is the chemical composition range of 0Cr27Al7Mo2? Why is aluminum so high?

0Cr27Al7Mo2 contains chromium 26.0~28.0%, aluminum 6.0~7.5%, molybdenum 1.5~2.5%, and iron as the balance. High chromium and high aluminum ensure the formation of a dense enough aluminum oxide protective film at 1400°C and maintain stable resistance. Molybdenum is responsible for high temperature strength; its aluminum content is the highest in the group, and the oxidation resistance limit is also increased accordingly.

What equipment is 0Cr27Al7Mo2 suitable for? What specifications can be supplied?

0Cr27Al7Mo2 is suitable for industrial high-temperature furnaces, laboratory equipment and extremely demanding heating elements, such as 1400℃-class electric heating wires in high-temperature heat treatment furnaces and test electric furnaces. We can supply wire/heating wire 0.05~7.5mm, rod 8~50mm, flat wire/flat strip and precision strip, with tensile strength 630~780N/mm² and elongation greater than 12%.
