Hot work steel with good high temperature strength and very good toughness, high resistance to thermal shock and wear, nitridable, good polishability
X 37 CrMo V 5-1
As-supplied condition: soft-annealed to max. 229 HB (770 N/mm²)
General fields of application: Tools for forging machines, dies, die inserts, extrusion tools, hot shearing knives and tools for plastics processin
If nitrided, the nitriding depth should not exceed the specified thickness otherwise internal thermal cracking may occur, reheating the work piece to 200 – 300 °C before commencing work is recommended. Also available in ESR grade. If grained or polished ES 235 W in EST grade should be used. We recommend our ES Maximum 500 steel for highly polished mirrored finishes and for the highest toughness requirements.
