Broder Metals Group supply the high strength variant of MP35N in two conditions:

  • AMS 5844 – solution treated and cold drawn bars: useful for where the ageing treatment will make the material too tough to machine economically. Material in this condition is supplied with an ageing capability test result for ageing to be carried out after machining of the component.
  • AMS 5845 – solution heat treated, cold drawn and aged bars: fully aged material so the machinist does not have to carry out their own ageing operation.
