Crucible Steel PEERLESS A Tool Steel, AISI H21
Categories:	Metal; Ferrous Metal; Tool Steel
Material Notes:	Peerless A is designed for tools which will run hot, at operating temperatures between about 600F and 1100F. The tools should not be water cooled in service, due to a high risk of thermal shock. Peerless A offers wear resistance approaching H19, with slightly better toughness at high temperature (over about 600F). It may be used at tool temperatures up to 1100F, with brief exposures to 1200/1250F. Information provided by Crucible Industries
