Technical characteristics

Soft-magnetic alloys have a high primary magnetic inductive capacity. These alloys magnetize themselves to a saturation in weak fields. The alloys, in which composition there are cobalt and nickel except for iron, relate to this category. Alloy grade 45N is a soft-magnetic. It has an increased magnetic inductive capacity and saturation induction. According to GOST 19 693−74, this material has a coercive force by induction that does not exceed 4 kA/m. Such alloys are essential in modern innovative technologies, spheres of accurate instrument engineering. It is also popular at manufacturing the electronic units, household appliances, details of laser techniques and metrologic-measuring equipment.

Relevance

45N grade is usually used in cores of small-sized and high-power transformers, relay actuators, chokes and details of magnetic circuits that operate while working at increased induction with a small bias or without it. It is utilized in electric machine industry, transformers and radio engineering, electrotechnical sphere of industry and in automation systems, teleautomatics, computationally measuring equipment.

An extra pure ferromagnetic iron, low-carbon electrotechnical steel (siliceous, unalloyed), low-coercive precision alloys on ferromagnetic basis also relate to this type of soft-magnetic alloys. They are melted in special metallurgic furnaces for obtaining required shapes. After that, they can be exposed to rolliing or forging. Soft-magnetic alloys are extensively used in modern industry. They are used for manufacture of transformers, cores for microphones, components of computer storage, magnetic antennas, details of electric machines, magnet cores that are intended to work in sea water.

Welding:

Type Description
limitedly weldable welding is possible at heating to 100−120°С and last heat treating
hardly weldable in order to obtain a qualitative welded joints, it is necessary to perform the following operations: before welding to heat details up to 200−300°C, heat treating (annealing) after welding
weldable
without stint
welding is done without further heat treating or previous heating
