    Description

    34ХН1М steel is used: for the manufacture of forgings of various parts of General engineering; solid-rolled rings for different purposes, disks, shafts, rotors of turbines and compressors, excavators, shafts, axles and couplings, gears, hubs, shaft-pinion, bolt, weight pins, and other critical high-load parts, which meet high requirements for mechanical properties and working temperatures up to +500 °C; backup rolls of rolling mills.

    Note

    Steel high-alloyed quality.
