Ezi D2 zouti asye materyèl se yon asye redi lè a, ak ap devlope dite sou refwadisman nan toujou lè. Pou evite Eskalad ak pou anpeche decarburization nan sifas la moso travay, kontwole atmosfè oswa vakyòm founo yo rekòmande. Si founo sa yo yo pa disponib, pake redi, basen sèl oswa vlope moso nan nan pur papye asye ap bay kèk degre nan pwoteksyon sifas nan pwosesis la redi. Pyès ta dwe gen dwa yo refwadi 150F, oswa yo kote yo ka gen pou fèt nan men nan fè, ak Lè sa a apeze imedyatman.

AISI D2 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization of the work piece surface, controlled atmosphere or vacuum furnaces are recommended. If these furnaces are not available, pack hardening, salt baths or wrapping the piece in stainless steel foil will provide some degree of surface protection in the hardening process. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately.
