Baosteel B23R085 Low Iron Loss, High Magnetic Susceptibility Ultra-thin Oriented Silicon Steel

I. Products

Baosteel Oriented Silicon Steel B23R085 is a cold rolled, high magnetic susceptibility silicon steel sheet with a thickness of 0.23mm, made using Baosteel's precision process (oxygen converter melting, hot rolling, cold rolling and annealing). Its core advantages are low iron loss and high magnetic induction:

The iron loss value (P1.7/50) is ≤0.85 W/kg, which significantly reduces energy loss and improves energy efficiency.

High magnetic permeability: the magnetic induction strength (B8) in the rolling direction reaches more than 1.92T, which reduces the size of the transformer core and saves material costs.

Surface Characteristics: Smooth and flat A-coat (semi-organic thin coating) provides excellent insulation, corrosion resistance and weldability, while optimising punching performance.

II. Main uses

B23R085 is designed for high-efficiency power equipment, widely used in:

Large power transformers: low iron loss characteristics to reduce no-load energy consumption, suitable for smart grid and new energy transmission needs.

Precision electronic equipment: such as inductors and reactors, using its magnetic direction consistency to improve energy efficiency and stability.

High-end manufacturing: including ultra-high voltage transformers, energy-saving motor cores, meeting green energy certification standards (e.g., EU IEC 60404).

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.
