( sinadaran abun da ke ciki, micro, wadanda ba karfe inclusions da hardenability) → abu → forging → zafi magani → dubawa → nika.

(2) 20CrMo karfe masana'anta piston tsarin hanya don ƙirƙira → normalizing → dubawa → machining → zafi magani → sandblasting → dubawa → nika.

(3) 35C Mr oV karfe masana'anta piston tsari hanya don ƙirƙira → zafi magani y dubawa (taurin) → machining → carburizing → dubawa (carburized Layer)

→ high zafin jiki tempering → quenching → tsaftacewa → low zafin jiki tempering → yashi ayukan iska mai ƙarfi → dubawa → nika.
