17-4PH 630 Bwalo lachitsulo chosapanga dzimbiri
Kufotokozera Kwachidule:
Saky Steel's 17-4PH / 630 / 1.4542 ndi imodzi mwazitsulo zodziwika bwino komanso zogwiritsidwa ntchito kwambiri zosapanga dzimbiri za chromium-nickel alloy zokhala ndi zowonjezera zamkuwa, mvula yowumitsidwa ndi kapangidwe ka martensitic. Amadziwika ndi kukana kwa kutu kwambiri pomwe amakhalabe ndi mphamvu zambiri, kuphatikiza kuuma. Zitsulo zimatha kugwira ntchito pa kutentha kuchokera ku -29 ℃ mpaka 343 ℃, ndikusunga magawo abwino. Kuphatikiza apo, zida zomwe zili mugiredi iyi zimadziwika ndi ductility wabwino ndipo kukana kwawo kwa dzimbiri kumafanana ndi 1.4301 / X5CrNi18-10.
17-4PH, yomwe imadziwikanso kuti UNS S17400, ndi chitsulo chosapanga dzimbiri cholimba cha martensitic. Ndizinthu zosunthika komanso zogwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga zakuthambo, nyukiliya, petrochemical, ndi kukonza chakudya.
17-4PH ili ndi mphamvu zambiri, kukana bwino kwa dzimbiri, komanso kuuma bwino poyerekeza ndi zitsulo zina zosapanga dzimbiri. Ndi osakaniza 17% chromium, 4% faifi tambala, 4% mkuwa, ndi pang'ono molybdenum ndi niobium. Kuphatikizana kwa zinthuzi kumapereka zitsulo zamtengo wapatali.
Ponseponse, 17-4PH ndichinthu chosunthika komanso chothandiza chomwe chimapereka kuchuluka kwazinthu zamagwiritsidwe osiyanasiyana.
