Heat-resistant alloy Alloy HT 70 (UNS N06008): technical specifications

Engineering and Technical Parameters of Alloy HT 70

Alloy HT 70 is a precision nickel-chromium (Ni-Cr) alloy designed for operation in extreme high-temperature environments. Its high chromium concentration (up to 30%) provides excellent resistance to high-temperature oxidation and scaling, which is a critical factor for the longevity of heating elements in industrial furnaces and installations. EV Group China produces this material in the form of wire and strip, certified to key international standards, ensuring consistent performance from batch to batch.

Chemical Composition and Alloying Elements of Alloy HT 70

The key performance characteristics of the material directly depend on the precise balance of alloying components. The nickel and chromium base guarantees the structural stability of the alloy under cyclic thermomechanical loads, while silicon is added to further enhance oxidation resistance.

Mechanical Properties under Normal Conditions

The alloy demonstrates retention of high strength characteristics within the operating temperature range, which minimizes the risk of creep and deformation of heating system components during operation. This ensures structural integrity and extends the service life of products.

Physical and Operational Constants of the Alloy

The material produced by EV Group China is characterized by high electrical resistivity, which is critical for resistance heaters, and inertness in aggressive gaseous environments. The nominal density of the alloy is 8.2 g/cm³.
