27QH095 Grain-Oriented Electrical Steel — 0.27 mm, 0.95 W/kg
27QH095: what it is and where it belongs
27QH095 is the conventional workhorse at 0.27 mm: 0.95 W/kg, wide availability, short lead time. It covers standard distribution transformers and OEM equipment where the design is mature and the priority is predictable supply rather than the last 0.05 W/kg.
Typical applications
Standard distribution transformers
Medium power transformers
OEM and packaged equipment
Repeat production with fixed core designs
Selection and processing notes
Ample supply from more than one mill keeps lead time short and price stable.
A 0.05 W/kg step to 27QK100 is often enough to hit a price target without changing thickness.
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 27Q095 equivalent. Buyers specifying to IEC or ASTM may treat this grade as the 0.27 mm, 0.95 W/kg tier; the equivalence sheet is supplied with the quotation so the substitution can be written into the purchase order without ambiguity.
