Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
1.2344 (DIN EN ISO 4957 : 2018-11) X40CrMoV5-1 1.2344 DIN EN ISO 4957 : 2018-11 Supersedes DIN EN ISO 4957 : 2001-02 Valid Germany X40CrMoV5-1 1.1.2 1)
1) Remark: X40CrMoV5-1 is an alloyed hot worked tool steel. In the hardened and tempered condition, it reaches a minimum of 50 HRC. Use: especially well suited for tools for the processing of light metal alloys through extrusion. Also for swage-pressed parts, mandrels and piercers in forging machines as well as dies and mandrels for the manufacture of screws, nuts and rivets. Especially well-suited for tenifer treatment.
