Non-oriented silicon steel / Standard CRNGO
Non-oriented · Standard
Standard CRNGO — 0.35 / 0.50 / 0.65mm Non-Oriented Electrical Steel
Cold-rolled non-oriented electrical steel in 0.35, 0.50 and 0.65 mm, grades 50W470 to 50W800, for industrial motor, generator and appliance laminations. Core loss P1.5/50 from 3.00 to 8.00 W/kg.
Supplied as
Coil, sheet or slit strip
Standard CRNGO ships in whichever form matches your stamping line.

01
Coil
Master coils and mill-edge coils to your inner diameter and coil weight.

02
Sheet
Cut-to-length sheet in standard and custom dimensions.
03
Slit strip
Precision slit to width with tight tolerance for stamping.

04
Laminations
Stamped motor and generator laminations to your drawing.
By thickness & grade
Three thicknesses, graded by core loss
Pick thickness first by your stamping and frequency needs, then grade by how much core loss you can trade for cost.
0.35 mm
The thinner standard gauge, for smaller motors and appliance laminations where loss matters more.
- Core loss P1.5/50≤ 3.00 W/kg
- Induction B50≥ 1.60 T
- Stacking factor≥ 0.96
0.50 mm
The most common gauge for industrial motors and generators — balanced loss and cost.
- Core loss P1.5/50≤ 4.70–6.00 W/kg
- Induction B50≥ 1.70 T
- Stacking factor≥ 0.97
0.65 mm
The thicker, most cost-efficient gauge, for large low-speed motors and appliance drives.
- Core loss P1.5/50≤ 8.00 W/kg
- Induction B50≥ 1.72 T
- Stacking factor≥ 0.97

FAQ
Sourcing Standard CRNGO from us
Which thickness should I choose — 0.35, 0.50 or 0.65mm?
0.35mm suits smaller motors and appliances where loss matters most. 0.50mm is the most common industrial choice, balancing loss and cost. 0.65mm is the most cost-efficient for large, low-speed motors where loss is less critical. Tell us your motor size and speed and we’ll recommend a thickness.
What’s the difference between 50W470, 50W600 and 50W800?
All three are 0.50mm — the number after “W” is the maximum core loss ×100 at 1.5T/50Hz. 50W470 has the lowest loss (≤4.70 W/kg) and highest cost; 50W800 has the highest loss (≤8.00 W/kg) at the lowest cost. Choose based on your efficiency target and budget.
Can you match a specific grade, like M400-50A?
Yes — we supply across GB, EN, JIS and AISI, and can cross-reference your grade to the Chinese equivalent. Send the grade or a datasheet and we’ll confirm the match and quote.
What’s the minimum order quantity?
MOQ depends on grade, thickness and width. Tell us your target volume and we’ll confirm what’s workable — trial quantities are possible for new projects.
How fast can you quote and ship?
Quotes come within 24 hours. 50W470/600/800 in common widths often ship from stock in days; non-standard widths typically take a few weeks.
Do you provide samples?
Yes — free samples are usually ready within about a week, so you can test core loss and stampability before committing.
Which standards and certifications do you hold?
Production runs under ISO 9001 and IATF 16949, with material to GB, EN, JIS or AISI grades and RoHS / REACH compliance. A mill test certificate ships with every order.
Can you cut to my sizes?
Yes — precision slitting to width, cut-to-length sheet, and stamped laminations to your drawing.
