Grade cross-reference

Look up a manufacturer grade code and see its key reference values next to equivalent designations in other standards. Equivalents are added only after they have been verified.

How to read a grade

Decoding a GO grade code

Manufacturer grade codes pack the key facts into a few characters. This example follows the reference manual’s convention.

B27R090
  1. B

    Manufacturer prefix

    Identifies the manufacturer’s own grade system — here, the reference manual.

  2. 27

    Nominal thickness

    Thickness × 100 → 0.27 mm. Listed thicknesses: 0.23 / 0.27 / 0.30 / 0.35 mm.

  3. R

    Type

    G = conventional · P = high induction · R = domain-refined high induction.

  4. 090

    Max core loss

    Core loss × 100 → 0.90 W/kg, measured at P1.7/50.

P1.7/50
Core loss in W/kg at a peak flux density of 1.7 T and 50 Hz. Lower is better.
B8
Magnetic flux density in tesla at a field strength of 800 A/m. Higher indicates better permeability.
Equivalent grade
A grade in another standard with comparable properties — always check the governing standard before substituting.
