Anotácia

This specification covers the standard requirements for wrought low-carbon iron having a carbon content of 0.015% or less with the remainder of the analysis being substantially iron. These alloys are not electrical steels such as are described in Specifications A 726 and A 840 but are instead primarily used in dc magnetic applications and are produced in a wide variety of mill forms such as forging billet and cold finished bar and wire as well as strip. Two alloy types are covered: Type 1 is a low-phosphorus grade and Type 2 contains a phosphorus addition to improve machinability. Apart from chemical requirements, alloy produced to this specification must exhibit guaranteed maximum values of coercive field strength when heat treated according to this specification. This specification has several useful appendices dealing with typical magnetic, physical and mechanical properties, heat treatment and magnetic aging.
