The D81SH discs are made with grade N42SH (SH = Super High Temperature) material. The SH material means that the magnets can be heated to 302° F without any permanent loss of magnetic strength, unlike standard neodymium magnets that begin to lose strength at 175° F.
This size is also available in grade N42 as part number D81 and in grade N52 as part number D81-N52.
