Standard Specification for Iron-Silicon Relay Steels
STANDARD published on 1.8.2019
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers wrought iron-silicon (Fe-Si) steels that are generally used in the manufacture of electromechanical devices, such as relays and solenoids, requiring higher electrical resistivity, higher permeability, and lower coercivity and residual magnetism than provided by either carbon steels or soft magnetic low-carbon irons. The steels covered in this specification are Steel type2 1, 1F, 2, 2F, 3. This specification covers steels in the form and condition required for fabrication into parts. The chemical composition requirements shall conform in carbon, manganese, silicon, phosphorus, sulfur, aluminum, and iron. Available forms and conditions are forging billet, hot-rolled product, cold-finished bars, strip, and wire. The material shall undergo heat treatment before performing conventional dc magnetic testing and shall conform to the required coercive force and coercive field strength.
