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.

Alloy 80NKHS used in the manufacture of small cores of transformers, relays and chokes, working in weak magnetic fields, screens; in the manufacture of a contactless relay of small thickness (0,05−0,02 mm) magnetic amplifiers and pulse transformer cores. To soft magnetic alloys are alloys whose composition includes cobalt, Nickel in addition to iron. Applied soft magnetic alloy 80NKHS, typically in electrical engineering, in the production of magnetic alternating magnetic field in the transformer industry, radio engineering, electrical engineering, systems automation, remote control, computer measurement technology. To the class of magnetically soft materials is a particularly pure ferromagnetic iron, electrical low carbon steel (non-alloy, silica), precision nizkotemperaturnye alloys with iron-Nickel, iron base, ferrimagnetic and ferromagnetic powder, composite. Such alloys are melted in a special metallurgical furnaces for production of necessary forms, exposing them to the bars later forging or rolling. Soft magnetic alloys are widely used in modern industry in the manufacture of transformer cores, microphones, components, memory for computers, magnetic cores which are designed for operation in sea water, parts for electric machines, magnetic antennas.
