Why standards differ

Same steel, different naming systems

China

GB/T 2521 (grain-oriented) and GB/T 2521.1 (non-oriented) — the standard we quote against by default.

JIS

Japan

JIS C 2553 (grain-oriented) and JIS C 2552 (non-oriented) — common on drawings from Japanese-spec equipment.

Europe

EN 10107 (grain-oriented) and EN 10106 (non-oriented) — common on European buyer datasheets.

AISI

United States

M-series designations — approximate mapping, since AISI doesn’t test to the exact same points as GB/JIS/EN.

FAQ

Using the equivalents chart

What’s the GB equivalent of 50W470?

50W470 is already the GB/T 2521.1 code — its JIS equivalent is 50A470 and its EN equivalent is M470-50A, both 0.50mm non-oriented steel with core loss ≤4.70 W/kg at 1.5T/50Hz.

What’s the GB equivalent of M400-50A?

M400-50A is an EN 10106 code. Its GB/T 2521.1 equivalent is 50W400, and its JIS equivalent is 50A400 — 0.50mm non-oriented steel with core loss ≤4.00 W/kg at 1.5T/50Hz.

My grade isn’t in this table — what do I do?

This chart covers our common stock grades. Send us your datasheet or the exact grade code and we’ll confirm the closest match and quote.

Are these equivalents exact?

GB, JIS and EN equivalents are close matches based on published standard test points. AISI M-numbers are approximate — different sources map them slightly differently, so always confirm against a datasheet before ordering.

Can you supply directly against my JIS or EN spec?

Yes — we regularly quote and test against JIS and EN specs directly, not just the GB equivalent. Send your spec and we’ll confirm.
