Baosteel Ultra-thin B18P075 Gold Energy-efficient Silicon Steel: Leading a New Era of Ultra-thin Energy-saving Core Materials

I. Products

Baosteel B18P075 is an ultra-thin gauge cold rolled grain-oriented silicon steel (CGO) that represents the top international technology level. Its core lies in:

1, the ultimate thin specification: nominal thickness of only 0.18mm, significantly reducing eddy current losses, is the pursuit of the ultimate efficiency of the cutting-edge choice.

Superior Magnetic Properties: Ultra-high magnetic susceptibility (B18P075 i.e. B800 ≥ 1.88T) with very low iron loss (typical P1.7/50 ≤ 0.75 W/kg). High magnetic susceptibility means that less material can be used or a more compact design can be achieved for the same magnetic flux; ultra-low iron loss translates directly into minimised energy loss during operation.

3, Precision Manufacturing: Baosteel's unique production process ensures smooth surface, uniform coating, tight thickness tolerance (±0.02mm), high stacking coefficient, and excellent processing performance.

4, stable and reliable: strict quality control system to ensure that the product performance is highly stable from batch to batch, to meet the stringent requirements of high-end applications for consistency.

II. Main uses

B18P075 is specially designed for the manufacture of ultra-high efficiency, high frequency, miniaturised power equipment core electromagnetic components, especially suitable for:

1, high-end ultra-high efficiency distribution transformer cores: especially for no-load loss requirements of extremely stringent energy efficiency (such as China's first class energy efficiency, the EU A + + +, the U.S. DOE 2023 Tier 3 and above), is the key material to achieve the ultimate energy saving.

2, high-frequency transformer core: such as high-end switching power supply (SMPS), new energy (photovoltaic inverter, electric vehicle on-board charger OBC), data centre power supply, precision instrumentation in the medium and high frequency transformers.

3, miniaturised reactor and inductor cores: to meet the trend of miniaturisation and lightweighting of electronic equipment.

4, Speciality transformers with extreme requirements for size, weight and efficiency.

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.
