Foreword
This document was drafted in accordance with the rules given in GB/T 1.1-2020,
Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents.
This document replaces GB/T 6983-2008 Soft magnetic iron. Compared with GB/T
6983-2008, the main technical changes are as follows:
-- Delete continuous casting square billet, continuous casting rectangular billet,
continuous casting slab and bloom from the scope of application (see Chapter
1 of the 2008 edition);
-- Add requirements for vacuum refining treatment (see 7.2);
-- Add requirements for delivery status (see 7.3);
-- Change the requirements for electromagnetic property index (see Table 2;
Table 2 of the 2008 edition);
-- Change the requirements for low-magnification inspection (see 7.6; 7.4 of the
2008 edition);
-- Add requirements for type inspection (see 9.2.1).

This document is applicable to magnetic iron hot-rolled (forged) bars (square, round,
flat), hot-rolled wire rods, cold-drawn round bars, hot-rolled plates (strips), and cold-
rolled plates (strips).
Note: Magnetic iron is also called soft magnet internationally.
