23QH100 Grain-Oriented Electrical Steel — 0.23 mm, 1.00 W/kg
23QH100: what it is and where it belongs
23QH100 is the value-engineered end of the 0.23 mm range: 1.00 W/kg on a conventional substrate. It is intended for standard distribution transformers and export units where the efficiency threshold is modest and the buying decision is dominated by landed cost per tonne rather than loss margin.
Typical applications
Standard distribution transformers
Value-engineered export units
Replacement cores and stock material
Projects specified by price per tonne
Selection and processing notes
Quote with thickness, coating and coil weight locked — this band is compared on price alone.
If Grade 2 certification is required, verify the design margin before committing.
Supply form and documentation
Supplied as master coil 900–1250 mm wide (508 mm ID, 2–5 t per coil), slit strip from approximately 100 mm at ±0.5 mm width tolerance, or cut-to-length sheets to your lamination size. Standard insulation coating is C5, with C6 heat-resistant and chrome-free options. Every shipment carries an MTC to EN 10204 3.1 stating grade, heat number, measured core loss and flux density, plus packing list and — for export — certificate of origin and a standard cross-reference sheet against IEC 60404-8-7, ASTM A876, EN 10107 and JIS C 2553.
Equivalent designations
Nearest mill equivalent: GB 23Q equivalent. Buyers specifying to IEC or ASTM may treat this grade as the 0.23 mm, 1.00 W/kg tier; the equivalence sheet is supplied with the quotation so the substitution can be written into the purchase order without ambiguity.
