Foreword

GB/T 14986 Soft Magnetic Alloys is divided into five parts as follows. -- Part 1. general requirements; -- Part 2. iron-nickel alloys; -- Part 3. iron-cobalt alloys; -- Part 4. iron-chrome alloys; -- Part 5. iron-aluminum alloy. This is the third part of GB/T 14986. This Part is drafted in accordance with stipulations in GB/T 1.1-2009. This Part is drafted as a replacement of iron-cobalt alloys part in GB/T 14986-2008 High Saturation Magnetic Induction Magnetic Compensate Alloys Depending on Temperature Variation Corrosion-resisting Iron-aluminum Permanent Permeability Soft Magnetic Alloys. In comparison with GB/T 14986-2008, there are several main technical changes as follows. -- Two trademarks 1J21 and 1J27, and relevant technical requirements are newly added (refer to 7.1 and 7.4; 6.1 and 6.4 in Version 2008); -- The stipulations of chemical compositions P and S in 1J22 become more rigorous; the stipulation that residual element Cr shall be ≤ 0.20% is added (refer to Table 3; Table 10 in Version 2008); -- The magnetic performance (B800, B1600, B2400) of 1J22 cold-rolled strip is enhanced, the magnetic performance (B1600, Hc) of cold-drawn wire, hot-rolled flat material and hot-rolled (wrought) bar is enhanced (refer to Table 5; Table 11 in Version 2008); -- The stipulations of surface quality of cold-rolled strip become more rigorous (refer to 7.6; 7.1 in Version 2008); -- The fundamental physical parameters of alloys and the typical performance value of alloy materials are added as a supplement (refer to Appendix B; Appendix B in Version 2008). This Part is proposed by China Iron and Steel Industry Association (CISA). This Part is summarized by National Technical Committee 183 on Steel Soft Magnetic Alloys - Part 3. Iron-cobalt Alloys

1 Scope
