What is M270-35A (1.0801) Non-Oriented Cold Rolled Electrical Steel?

Grade :	M270-35A
Number:	1.0801
Classification:	Alloy steel with special physical properties
Density:	7.65 g/cm ³
Standard:	EN 10106: 2007 Cold rolled non-oriented electrical steel sheet and strip delivered in the fully processed state

M270-35A (1.0801) non-oriented cold rolled electrical steel is a fully processed, cold-rolled non-grain-oriented (CRNGO) silicon steel grade that conforms to the European standard EN 10106:2015 for cold-rolled non-oriented electrical steel strip and sheet delivered in the fully processed state. It is also designated under the European steel numbering system as 1.0801 .

 

Understanding the Grade Designation M270-35A

The grade name "M270-35A" follows the European EN designation system and provides critical information at a glance:

Part of Designation	Meaning	Value/Interpretation
M	Magnetic material / electrical steel	–
270	Maximum specific total loss at 50 Hz and 1.5 T	2.70 W/kg
35	Nominal thickness of the material	0.35 mm
A	As-sheared / fully processed state with insulation coating	–

 

The steel number 1.0801 is the numeric identifier for the same material under the European steel numbering system, used for alloy steel with special physical properties

 

 

Unlike grain-oriented silicon steel (CRGO), where crystal grains are precisely aligned to achieve superior magnetic properties in a single rolling direction, non-oriented electrical steel has crystal grains distributed randomly within the deformed and annealed steel sheet. This random grain orientation gives the material isotropic magnetic properties – meaning it exhibits uniform magnetic performance in all directions within the plane of the sheet. This characteristic is essential for applications involving rotating magnetic fields, such as electric motor stators and rotors, where magnetic flux changes direction continuously

 

M270-35A (1.0801) non-oriented cold rolled electrical steel is recognized under multiple international standards. Understanding these equivalents helps manufacturers specify materials correctly and source from global suppliers with confidence.

 

Primary Standard: EN 10106:2015

The governing standard for M270-35A is EN 10106:2015 – "Cold rolled non-oriented electrical steel strip and sheet delivered in the fully processed state". Materials supplied to this standard are fully processed, meaning they possess all required magnetic properties in the as-delivered condition without requiring additional heat treatment from the customer.

 

Equivalent Grades Across International Standards

Depending on the manufacturing standard and regional classification, M270-35A may also be referenced under the following equivalent grade designations:

Standard	Equivalent Grade	Core Loss P₁.₅/₅₀ (W/kg)

Element	Typical Content	Role and Effect
Silicon (Si)	1.5% – 3.0%	Increases electrical resistivity; reduces eddy current loss; enables core loss target of 2.70 W/kg
Carbon (C)	Very low (≤0.02%)	Kept minimal to prevent magnetic aging and increased hysteresis loss
Manganese (Mn)	0.08% – 0.20%	Improves hot ductility and combines with sulfur
Aluminum (Al)	≤0.005% (typical)	Helps control grain size; excess can degrade magnetic properties
Sulfur (S)	≤0.003%	Ultra-low sulfur improves magnetic permeability
Phosphorus (P)	≤0.015%	Minimized to avoid brittleness
