Assab Steels ASSAB XW-42 Cold Work Steel
Categories:	Metal; Ferrous Metal; Carbon Steel; High Carbon Steel; Chrome-moly Steel; Tool Steel; Cold Work Steel
Material Notes:	XW-42 is a high-carbon, high chromium tool steel alloyed with molybdenum and vanadium characterized by: High wear resistance High compressive strength High hardness after hardening Good through-hardening properties Excellent dimensional stability in hardening Good resistance to tempering-back. XW-42 is used when cutting thicker, harder materials; when forming with tools subjected to bending stresses and where high impact loads are involved. XW-42 can be supplied in various finishes, including the hot-rolled, pre-machined and fine machined condition. XW-42 is a good choice for inserts in larger tools as well as deep drawing tools. AISI D2
