Electrical steel used to build transformer cores, where magnetic properties rather than mechanical strength decide the grade.
Core steel is the part of a transformer that decides how much energy is lost simply by being switched on. Unlike structural steel, it is bought for magnetic behaviour, and the grade, thickness and coating carry that. Handling matters as much as grade: the material is brittle at the edges and sensitive to mechanical stress, so bent or burred laminations raise losses even when the steel itself is right. SourcifyChina supplies core material to the grade your design calls for, with packaging that keeps it flat.
No load losses higher than the design predicted because of grade substitution
Laminations arriving bent or damaged at the edges and raising core loss
Coating damage during slitting affecting interlaminar insulation
Supply variation forcing design margins to be widened
Difficulty sourcing a specific grade and thickness in modest quantities
Grade supplied as specified rather than substituted for what is in stock
Slitting and edge condition considered as part of the supply
Packaging specified so laminations arrive flat and undamaged
Coating type confirmed against your core building process
Same grade and source held across repeat orders

Yes. Tell us the widths or lamination sizes required and we will confirm what the mill can provide.
Yes. Substitution is only made with your written agreement.
It depends on grade availability and mill schedule and is confirmed with the quotation.
This depends on the mill and is confirmed on request.
Send the capacity duty or drawing you need for silicon steel for transformers and we will match it to the factory that builds it and quote it in writing.
