ХН75ТБЮ - ЭИ869 sheet, round, wire

ХН75ТБЮ - ЭИ869 sheet, round, wire

Alloy heat-resistant Nickel-based stamps ХН75ТБЮ (ЭИ869) used in the production of flat springs, rotors, disks, fasteners and various other parts which must be operated at temperatures up to +650 °C. Also, the alloy used in the manufacture of parts of pipe fittings, welded assemblies.

NTD regulates the quality
Materials processing thermo-chemical, thermal B04 According to ST CKBA 016−2005
Shaped bars В32 According to the technical condition 14−1-272−72

Technical characteristics of the brand ХН75ТБЮ:
Welding:
weldability limited — welding is possible in the process of heating up to temp. 100−120? C and further thermal treatment
konovalivka in order to obtain quality welded joints, it is necessary to perform additional operations: during welding heating up to temp. 200−300°C, heat treatment (annealing) after welding.
Welded without any restrictions — welding is carried out without further heat treatment and pre-heating.
