23Q110 CRGO Silicon Steel: Properties, Composition, and Best Uses

What Is 23Q110 CRGO Silicon Steel? 

Before we examine properties, let's decode the naming. 23Q110 CRGO silicon steelconventional-type cold-rolled grain-oriented electrical steelIEC 60404-8-7GB/T 2521 standards.

 

• 230.23 mm.
• Q → Conventionally processed CRGO silicon steel.
• 110 → Maximum guaranteed core loss=1.10 W/kg (at 1.7 T / 50 Hz).

 

"Conventional type" means it achieves excellent magnetic directionality through standard grain orientation processes - without laser domain refinement - delivering an ideal balance of performance and cost-effectiveness for most distribution and power transformer applications.

Compared to non-oriented electrical steel (used in motors where magnetic flux rotates), 23Q110 CRGO silicon steel where crystal grains align with the rolling direction. This unique metallurgical structure gives it when flux flows along the rolling axis - which perfectly matches transformer core designs.

 

Key Properties of 23Q110 CRGO Silicon Steel

 

Its crystal grains are precisely aligned during cold rolling, making the steel highly magnetic (easy to magnetize) along the rolling direction but poor in transverse directions.

 

Maximum iron loss is \(1.10 \text{ W/kg}\) at \(1.7 \text{ Tesla}\) and \(50 \text{ Hz}\), meaning minimal heat dissipation during operation.

 

Allows the material to carry high magnetic flux with low excitation current.

 

Substantially limits the steel's expansion and contraction in magnetic fields, reducing the humming or buzzing noise often heard in electrical equipment.

Typical Chemical Composition of 23Q110 CRGO Silicon Steel

	2.8% – 3.4%	Increases electrical resistivity → lowers eddy current loss. Essential for soft magnetic properties.
	<= 0.03%	Controlled to minimal levels; excess carbon degrades magnetic aging.
	0.10% – 0.20%	Improves hot workability.
	<= 0.02%	Minimized to avoid brittleness.
	<= 0.005%	Low sulfur ensures Goss texture formation during final annealing.
	<= 0.005%	Tightly controlled to avoid adverse grain growth.
	<= 0.003%	Low nitrogen prevents grain boundary embrittlement.

 

Each 1% addition of silicon increases electrical resistivity by approximately +15–20% and reduces eddy current loss proportionally. At 3.0% silicon, CRGO silicon steel achieves the optimal trade-off between high resistivity and mechanical workability. With 3.0–3.2% Si, 23Q110 delivers peak permeability and stable core loss across a wide temperature range - essential for continuous transformer operation.
