Both are non oriented steel grades.
M19 lamination steel.
Small hysteresis area resulting in low power loss per cycle low core loss and high permeability.
The m stands for magnetic material.
The number is representative of the core loss of that grade.
Standard grades from m 15 to m 47 are available with the advantages.
Electrical steel also called lamination steel silicon electrical steel silicon steel relay steel or transformer steel is specialty steel tailored to produce certain magnetic properties such as a small hysteresis area small.
Thickness mm core loss 1 5t 50hz.
Ak steel di max m 19 nonoriented electrical steel categories.
Laminations sotek specializes in electrical steel laminations stacked stator core rotor core assembly manufacturing for motors and generators.
Electrical steel lamination steel silicon electrical steel silicon steel relay steel transformer steel is an iron alloy tailored to produce specific magnetic properties.
Due to substantially higher material cost thin electrical steel is used primarily for high performance and high frequency applications.
The american iron and steel institute type numbers and ak steel designations for electrical steel grades con sist of the letter m followed by a number.
They all are non oriented electrical steel fully processed m15 are available in two.
C 4 insulation is best for punched laminations where only a moderate degree of surface insulation is required but good die life and minimum effect on lamination factor are very important.
What is a lamination.
Electrical steel is usually manufactured in cold rolled strips less than 2 mm thick.
Thin electrical steels are available in one grade equivalent to m19 and are made by re rolling standard silicon steel.
This inorganic surface treatment equivalent to astm type c 4 coating is produced by special chemical and thermal processing of the steel surface.
More detailed information about these two types of steels can be found in the metals handbook.
Aisi type equivalent of m15 m19 and m27 are astm equivalent of 36f145 36f155 and 36f175 respectively.
