Material Notes:

Orvar 2 Microdized is a chromium-molybdenum-vanadium alloyed steelORVAR® 2M / AISI H13 is a conventionally produced hot work tool steel with overall good ductility, toughness, wear resistance, hardenability and machinability. ORVAR 2 Microdized is characterized by: Good resistance to abrasion at both low and high temperatures High level of toughness and ductility Uniform and high level of machinability and polishability Good high-temperature strength and resistance to thermal fatigue Very limited distortion during hardening.Applications: Tools for Extrusion-Dies, Backers, dieholders, liners, dummy blocks, stems; Plastic Molding Applications- Injection moulds, Compression/transfer moulds; and Sever cold punching, scrap shears, hot shearing, shrink rings(eg for cemented carbide dies), wear-resisting parts.
