Biphase Stainless Steel
High Temperature Alloy
◆ F51 (31803) ndi duplex zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito kwambiri popanga mafuta wowawasa ndi gasi, poyenga mafuta, mankhwala, feteleza, petrochemical ndi madera ena, popanga makina opangira kutentha, condensing coolers, etc., zomwe zimakonda kuyika dzimbiri komanso kupsinjika kwa zida zamagetsi. M'malo mwa 304L, 316L austenitic chitsulo chosapanga dzimbiri.
◆ F53 (S32750) ndi chitsulo chosapanga dzimbiri chosapanga dzimbiri chokhala ndi nayitrogeni wowonjezera, chomwe chimagwiritsidwa ntchito makamaka pazida zamankhwala, petrochemical ndi m'madzi zomwe zimafuna mphamvu zapadera ndi kukana dzimbiri.
◆F55 (S32760) ndi chitsulo chosapanga dzimbiri cha duplex chokhala ndi mphamvu zambiri, kukana kwambiri ku dzimbiri kwa chloride komweko ndi kupsinjika kwamphamvu, komanso kuwotcherera.
◆329 (S32900) ili ndi kukana kwa okosijeni kwabwino, kukana kwa dzimbiri, mphamvu yayikulu, ndipo ndiyoyenera kumadera monga kukana kwamadzi am'nyanja.
◆ Chitsulo cha A4 (0Cr17Mn13Mo2N) ndi chitsulo chamagulu awiri, ndipo kukana kwake kwa dzimbiri ndikwabwino kuposa zitsulo zomwe zimagwiritsidwa ntchito nthawi zambiri za austenitic zomwe zimakhala ndi Mo 2% -3%. Itha kugwiritsidwa ntchito ku feteleza ang'onoang'ono amankhwala, zida zonse za urea, etc.
◆S31050 ili ndi kukana kwakukulu kwa chloride stress corrosion cracking, kukana kwambiri kutsekera dzimbiri ndi dzimbiri.
◆ U3 ili ndi anti-scouring ndi anti-corrosion properties, ndipo nthawi zambiri imagwiritsidwa ntchito popanga ma valve, mipando ya valve ndi zigawo zina zamkati za valve.
◆HD imagwiritsidwa ntchito kwambiri m'makampani amagetsi, mafakitale opanga zithunzi, mafakitale a petrochemical, magalimoto oyendetsa magalimoto ndi mapampu ena oyendetsa mafuta othamanga.
◆C4 ndi yoyenera kwa osakaniza okhazikika, osakaniza, osakaniza, osakaniza opingasa ndi mafakitale ena a makina.
◆ DS-2 ali dzimbiri kukana mu kutentha anaikira sulfuric asidi, ndi oyenera makina makampani mu kutentha anaikira sulfuric acid makampani.
