Product Inquiry

Product Introduction:

Semi-process NGO Silicon Steel provide customers with personalized customization, and the naming rules are specified separately. At present, it includes CRML64 series, and CRML49 series, S85, 50SP560E5, 65SP630E5 and 50SP450E5 for high efficiency motors. Semi-process Silicon steel of LY Steel meets the requirements of hazardous substance requirements such as ROSH and REACH.

Magnetic Property Standard Value:

Grade	Nominal thickness (mm)	Theoretical density (kg/dm³)	Max core loss P _15/50(W/kg)	Min magnetic induction B ₅₀ (T)
50LW470	0.5	7.75	≤3.8	≥ 1.66
50LW600	0.5	7.85	≤4.2	≥ 1.70

Note:
1. The magnetic properties in the table are not the magnetic properties when leaving the factory, which are the magnetic properties of semi-process Silicon steel after heat treatment according to the specified process.
2. The semi-process Silicon steel can obtain excellent magnetic properties by stress relief annealing after punching, and the interlayer resistance can be changed by bluing.

Typical Value of Magnetic Property:

Grade	Nominal thickness (mm)	Theoretical density (kg/dm³)	Core Loss P _15/50(W/kg)	Magnetic induction B ₅₀ (T)
50LW470	0.5	7.75	3.1	1.68
50LW600	0.5	7.85	3.7	1.72

Attention:
1. Measurement ofmagnetic propertiesafter heat treatment according to specified process is made in accordance with GB/T3655-2022. The number of the transverse and vertical samples are the same.
2. P15/50 is the core loss with 1.5T and 50Hz.
3. B50 is the magnetic induction with 5000A/m.

Typical Value of Magnetic Property:

Grade	Thickness (mm)	Yield strength (N/mm²)	Tensile strength (N/mm²)	Elongation (%)	Hardness HV5
50LW470	0.5	440	470	25	170
50LW600	0.5	340	370	33	145

Remarks: The tensile test is in accordance withGB/T 228.1-2021. Mechanical properties are transverse results, the mechanical property of silicon steel is usually used as a reference value for processing, not as a guarantee value for delivery.

Supply Standard:

Thickness tolerance	Width tolerance	Longitudinal thickness deviation	Transversal thickness deviation
GB/T17951.2-2014	0—+1.5mm or in accordance with width requirement of customer	±0.010mm	±0.015mm

Other size, shape, weight and tolerance are controlled in accordance with GB/T17951.2-2014.
The product is delivered as side trimmed, mainly with thickness of 0.50, 0.56, 0.65, 072mm, conventional delivery weight is 5-7t, 8-10t.
