Title:
SOFT MAGNETIC IRON
Document Type and Number:
WIPO Patent Application WO/2022/091984
Kind Code:
A1
Abstract:
The present invention provides technology that achieves high levels of both magnetic properties and machinability, which couldn't be achieved with just conventional machinability-improving technology utilizing MnS. This soft magnetic iron has a component composition containing, in mass%, 0.02% or less C, 0.15% or less Si, 0.01 to 0.50% Mn, 0.002% to 0.020% P, 0.001% to 0.050% S, 0.05% or less Al, 0.0100% or less N, and 0.001% to 0.30% Se, with the remainder comprising iron and unavoidable impurities.
