Manufacture of ASTM B677 TP904L Nonoriented Electrical Steel Fully Processed Types :

Typical Melting and Casting :
These fully processed electrical steels may be made by basic-oxygen, electric-furnace, or other steelmaking practice.
These electrical steels are characterized by low carbon, usually less than 0.020 %. The principal alloying element is commonly silicon,

but aluminum up to about 0.8 % is sometimes used instead of or in addition to silicon, depending on mill-processing practice for the desired magnetic grade.Individual producers will often have different silicon or aluminum contents for a particular grade because of intrinsic
mill-processing procedures.
Sulfur content is typically less than 0.025 % and is usually lowest in the numbered types representing lowest core loss. Manganese is typically present in amounts between 0.10 and0.40 %. Phosphorus, copper, nickel, chromium,molybdenum, antimony, and tin are usually present only in
residual amounts except in the higher numbered core-loss types in which phosphorus up to 0.15 % and tin or antimony up to 0.10 % may be present.
The producer is not required to report chemical composition of each lot except when a clear need for such information has been shown. In such cases, the analyses to be reported shall be negotiated between the producer and the user.
Typical Rolling and Annealing— The processing sequence for fully processed, nonoriented electrical steel comprises hot-rolling, annealing, pickling, cold-rolling, and decar burizing annealing.
When changes in the manufacture of the material are believed to exert possible signif i cant effects upon the user’s fabricating practices and upon the magnetic performance to be obtained in the specif i ed end use, the producer shall notify the user before shipment is made so the user has an opportunity to evaluate the effects.
