The material labeled 45N refers to the magnetically soft type of precision alloys, and therefore has a significant magnetic permeability and induction of technical saturation. Like all such raw materials, this alloy is able to fully saturate with magnetic energy even under the influence of a small magnetic field. A characteristic feature of such materials is the presence in their composition of cobalt and nickel, because these chemical elements determine the main operating characteristics of raw materials of soft magnetic type.
using
The scope and principles of using products from precision alloys depend fully on their individual characteristics. Such raw materials are very important in the production of electrical equipment, power engineering and the manufacture of magnetic cores of various transformer devices. Also, without such semi-finished products, the production of relay equipment and chokes is not complete. It is simply irreplaceable alloy 45N and its similar materials in the production of television equipment, measuring instruments and a variety of computing equipment.
production
The production of soft magnetic materials is characterized by the complexity and laboriousness of the technological process, which requires the use of special metallurgical furnaces and complete dedication from the staff. After giving the ingot the desired shape in the furnace, it is processed by rolling on rolling mills of various types. The finished product has a set of unique performance characteristics and high surface quality.

Weldability indexes
| The alloy has limitations on weldability | The welding process requires some preliminary preparation (warming the contacting surfaces to one hundred and one hundred and twenty degrees and subsequent heat treatment of the seam zone) |
| The alloy has no weld constraints | No additional operations are required |
| Hard to weld material | It is necessary to warm the contacting surfaces to two hundred or three hundred degrees, the subsequent annealing and heat treatment after the end of the welding process |
