27QH100 Grain-Oriented Electrical Steel — 0.27 mm, 1.00 W/kg
27QH100: what it is and where it belongs
27QH100 is the volume tier at 0.27 mm, at 1.00 W/kg. It is selected when the buyer values delivery reliability and price stability over loss performance — box substations, reactors and standard units in long production runs.
Typical applications
Box and compact substations
Reactors and voltage regulators
Standard distribution transformers
Long production runs with fixed annual volume
Selection and processing notes
Best price stability in the range because several sources supply this tier.
Reactor applications should confirm the loss and noise budget before adopting a conventional grade.
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 27Q100 equivalent. Buyers specifying to IEC or ASTM may treat this grade as the 0.27 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.
