However, a low-temperature heat treatment may be employed by the user to eliminate stresses introduced by fabrication of the material into cores. The specified thickness and mechanical requirements such as lamination factor, ductility, and hardness are given. Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment is usually not necessary.

This specification covers the detailed requirements for flat-rolled nonoriented fully processed electrical steel intended primarily for commercial power frequency applications in magnetic devices. Please read our License Agreement regarding materials data and our Privacy Policy.

Are you an Engineering professional? In addition, cold finishing plus strip annealing produce a smooth surface and reduce buckles and waves, resulting in excellent flatness and a high stacking factor. The electrical steel shall conform to the specified magnetic properties including: With these materials, achievement of magnetic properties becomes the responsibility of the user. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Desirable core-loss and permeability characteristics are developed during mill processing, so additional heat treatment by the user is usually not necessary. Link to Active This link will always route to the current Active version of the standard.

Allegheny Ludlum includes some mechanical property data at htt p: DI-MAX grades have superior permeability at high inductions, low average core loss and good gauge uniformity. These electrical steels are low-carbon, silicon iron, or silicon-aluminum-iron alloys that may be made by basic-oxygen, electric-furnace, or other steelmaking practice.
