Material characteristic and use

Properties BOHLER M461 EXTRA is precipitation hardening steel grade for plastic moulds, 
featuring good machinability in the as supplied, precipitation hardened condition
BOHLER M 461 EXTRA meets a great number of highly exacting requirements both
in the process of mould production by featuring: best electric discharge machining 
properties, excellent polishability, excellent dimensional stability during heat
treatment and machining, excellent nitriding properties, easy machinability with high 
hardness as well as the processing of plastics by offering high compressive 
strength with high toughness, high wear resistance.
   
Application ● High-precision plastic injection moulds e.g. for the production of camera parts
   and electronic parts.
● Compression moulds for all types, e.g. for plastic containers.
● Moulds for the processing of elastomers.
● Moulds for the production of packing rings (O-ring seals)
● Moulds for the productiong of tire segments (rubber materials)
● High-precision components for mechanical engineering. 
   
As-supplied condition Precipitation hardened to 38 - 42 HRC (stock standard)
Alternative solution annealed ~32 HRC
