Magnetic properties of stainless and hardened steels

Magnetic properties of alloys

The types of magnetic alloys

— ferromagnetics,

— diamagnetics,

— paramagnetic.

ferromagnetically the greatest magnetic susceptibility. Ferromagnetic materials the relative magnetic permeability can be magnetically soft and magnetically hard. The paramagnetic this quality is expressed much weaker. Diamagnetics do not have the resultant magnetic moment, have a negative charge. Magnetic properties of diamagnetic push them out of the magnetic field. These include zinc, copper, gold, and other

Soft magnetic alloys

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-based,

The percentage composition of the alloy 27KKH, GOST 10 994 — 74

Fe Mn Si C Ni Cr P S Co
basis 0.2 — 0.4 ≤ 0.25 ≤ 0.04 ≤ 0.3 0.3 — 0.6 ≤ 0.015 ≤ 0.015 26.5 — 28

The magnetic properties allow to apply such an alloy in the manufacture of precision electronic devices, production of metrological and measuring equipment.

Magnetic hard alloys

The permalloy is characterized by high permeability in weak fields. Its composition is divided into low-Nickel containing up to 50% Ni and high Nickel containing up to 82% Ni. The membership of each alloy to a particular group depends on the severity of the electromagnetic properties.
