23QG085 Grain-Oriented Electrical Steel — 0.23 mm, 0.85 W/kg
23QG085: what it is and where it belongs
23QG085 sits one tier below 23GK080 and is the grade sales engineers reach for when a tender only requires compliance and the customer will not pay for loss margin. Performance is still Hi-B class at 0.85 W/kg, so noise and temperature behaviour remain predictable — unlike dropping straight to conventional substrate.
Typical applications
Grade 2 oil-immersed distribution transformers
Unit substations and packaged substations
Tenders that specify compliance without margin
Projects where a small price step decides the award
Selection and processing notes
Stays on Hi-B substrate, so low-noise designs do not need structural compensation.
The price gap to 23QK095 is small; check whether Grade 2 compliance is actually required before stepping down further.
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: B23R085 / B23P085. Buyers specifying to IEC or ASTM may treat this grade as the 0.23 mm, 0.85 W/kg tier; the equivalence sheet is supplied with the quotation so the substitution can be written into the purchase order without ambiguity.
