23QG090 Grain-Oriented Electrical Steel — 0.23 mm, 0.90 W/kg
23QG090: what it is and where it belongs
23QG090 is the practical bridge between Hi-B performance and conventional pricing at 0.23 mm. At 0.90 W/kg it still holds Hi-B flux density, which keeps excitation current and noise in the range most customers expect, while the loss tier is relaxed enough to compete on price in volume box-substation work.
Typical applications
Grade 2 oil-immersed distribution transformers
Volume box substations
Medium-rating power transformers
Mixed production lines needing one compromise grade
Selection and processing notes
Preferred over 23QK095 when noise or excitation current is part of the acceptance criteria.
Ideal single-grade compromise for plants building both oil-immersed and dry-type units.
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: B23P090. Buyers specifying to IEC or ASTM may treat this grade as the 0.23 mm, 0.90 W/kg tier; the equivalence sheet is supplied with the quotation so the substitution can be written into the purchase order without ambiguity.
