27QH110 Grain-Oriented Electrical Steel — 0.27 mm, 1.10 W/kg
27QH110: what it is and where it belongs
27QH110 is the most price-sensitive tier we supply: 1.10 W/kg at 0.27 mm, conventional substrate. It is for rural network upgrades and cost-limited distribution programmes where the only technical requirement is to clear the efficiency threshold.
Typical applications
Rural network upgrade programmes
Cost-limited distribution transformers
Tenders decided on price per tonne
Stock and replacement cores
Selection and processing notes
This band includes semi-process material: sample-test core loss and thickness tolerance per batch.
Lock the acceptance criteria into the contract rather than relying on the grade designation alone.
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 27Q110. Buyers specifying to IEC or ASTM may treat this grade as the 0.27 mm, 1.10 W/kg tier; the equivalence sheet is supplied with the quotation so the substitution can be written into the purchase order without ambiguity.
