AMA posachedwapa yatulutsa kafukufuku watsatanetsatane wamasamba opitilira 180+ m'malo ake pamsika wa 'Malleable Iron Pipe Fittings' omwe amafotokoza zinthu zosangalatsa za msika ndikuthandizira zochitika zachitukuko mpaka 2025. ndi magawo ofunikira abizinesi pamodzi ndi ndemanga pazomwe zikuchitika, zoyendetsa kukula.
Chitsulo chosungunuka, chopangidwa ngati chitsulo choyera, ndi carbide yosasunthika yopangidwa mu pearlitic matrix. Annealing imachitika kuti asinthe mawonekedwe oyamba a brittle kukhala mawonekedwe osasunthika. Chithandizo cha annealing chimapangitsa kuti machinability, ductility, ndi kulimba kwake. Zitoliro zachitsulo zosasunthika zimapangidwa makamaka kuchokera ku chitsulo chonyezimira ndi ma alloys omwe amapangidwa ndi chitsulo, kaboni, ndi silicon. Mapaipi osungunuka amagwiritsidwa ntchito kulumikiza mapaipi kapena machubu awiri kapena kuposerapo, kulumikiza chitoliro ku zida zina, kusintha komwe kumachokera madzimadzi, kapena kutseka chitoliro.
