Baosteel B23R080 high performance transformer silicon steel, iron loss ≤ 0.8W/kg

I. Products

Explanation of grades: B23R080

B23R080: B (Baosteel), 23 (thickness 0.23mm), R (refinement of magnetic domains), 080 (iron loss value P1.7/50 ≤ 0.80W/kg).

Technical Status.

Baosteel independently researched and developed the world's highest grade of oriented silicon steel, the use of laser scribing technology, to achieve the optimisation of magnetic domains, the world's lowest iron loss, the highest permeability, to fill the gaps in China's high-end silicon steel.

Density 7.65×103 kg/m3, burr height ≤0.020mm, residual curvature ≤10mm, ensuring geometric precision and electromagnetic stability.

II. Main uses

Core materials for high-efficiency power equipment.

Ultra-low loss transformers: Specially used in the manufacture of distribution transformers with energy efficiency levels above S15 (e.g., S15-M-200/10, 400/10), with no-load loss reduced by more than 30% to meet the world's stringent energy-efficiency standards.

Green energy storage system: used in generator cores of world-class compressed air energy storage power stations (e.g. Hubei Yingcheng 300MW project), supporting the demand for high conversion efficiency of ‘super chargers’.

High-voltage transmission equipment: Used in ODFPS-100000000/1000 extra-high voltage transformers to ensure the stability of long-distance power transmission.

Industry coverage: power grid, new energy (wind power/photovoltaic inverters), rail transport, industrial motors.

III. Storage and maintenance

1，Moisture and rust prevention: The storage environment should be kept dry (relative humidity ≤ 60%), avoiding contact with acid, alkali and other corrosive substances. If stored for a long time, it is recommended to use anti-rust oil or vacuum packaging to protect the surface coating.

2，Physical protection: Avoid mechanical collision or heavy pressure to prevent deformation of steel coils or coating damage. Use special pallets when stacking and control the stacking height to reduce the bottom load.3,33333333332123123123546974124

3，Temperature control: Ideal storage temperature is between 10°C and 30°C to avoid high temperature environment that may cause coating aging or magnetic property degradation.

4，Pre-processing: If cutting or stamping is required, make sure the equipment is clean to avoid scratching the surface with impurities; clean up debris in time after processing to prevent oxidation or degradation of insulating properties.

IV. Payment modalities

Only support T/T payment, the implementation of the FOB standard, the first to determine the variety and grade of silicon steel, sign the contract prepayment of 40%, in the delivery period the goods ready to send to the designated domestic port (such as Tianjin Port), after settlement of the final payment, the goods loaded on the ship.

V. Summary

Baosteel B23R080 represents the top technological strength of China's oriented silicon steel, and has become the core material solution for high-efficiency transformers and green energy storage equipment with the world's leading laser scribing process and ultra-low iron loss characteristics (P1.7/50 ≤ 0.80W/kg). With both spot supply capability and customised technical support, we help our customers to enhance the competitiveness of their products in terms of energy efficiency.
