Material properties
Density: 7.7g/cm³; kusimba simba: 590MPa; goho simba: 245MPa; kureba: 15%; kuoma HBW: 269; kudzima uye kupisa kuoma: 55HRC.
Mechanical maitiro
1.4112 ndeyepamusoro kabhoni martensitic simbi isina tsvina. Zvigadzirwa zvayo zvemagetsi zvinonyanya kusanganisira simba, kuoma, kuoma, etc. Pamusana pehuwandu hwekabhoni uye chromium, rudzi urwu rwesimbi rune simba rakakwirira uye kuoma uye rinogona kumira kudzvinyirira kukuru uye kupfeka. Panguva imwecheteyo, nekuda kwekusimba kwayo kwakanaka, rudzi urwu rwesimbi haruna nyore kuputika uye rinogona kushandiswa munzvimbo dzakaoma zvikuru. Inopesana nekuora kubva mumhepo yakapfava, mhute yemvura yakachena, ammonia, zvigadzirwa zvakawanda zvepetroleum uye organic zvinhu, uye dzakasiyana siyana dzisina kusimba acidic nharaunda. The annealing tembiricha yakadzika kwazvo, uye kuoma mushure mekudzima kwakakwira. Iko kuoma kunowanzosvika HRC56-58. Iyo ine yakanaka corrosion resistance (magnetic) uye yakasimba kuoma.
Nzvimbo dzekushandisa
Nekuti 1.4112 simbi isina tsvina ine yakanakisa corrosion resistance uye mechanical properties, inoshandiswa zvakanyanya mupetroleum, chemical industry, marine engineering, mota, chikafu nezvimwe. Mumaindasitiri epetroleum nemakemikari, nekuda kwekushomeka kwayo kwegora, inoshandiswa kugadzira mareactor, mapaipi nemimwe michina. Mumunda weinjiniya yemugungwa, inoshandiswa kugadzira zvikamu zvakakosha zvezvikepe uye mapuratifomu ekumahombekombe. Mumunda wemotokari, inoshandiswa kugadzira zvinhu zvakaita senge masisitimu emagetsi uye fasteners. Mumunda wekudya, unoshandiswa kugadzira midziyo yekubikira nemidziyo yekugadzira chikafu nekuda kwehutsanana hwayo.
Process performance
Maitiro ekugadzira 1.4112 simbi isina tsvina anonyanya kusanganisira welding, kupisa kupisa uye kugadzirisa zvivakwa. Iyi simbi yemhando ine yakanaka welding performance uye inogona kugadzirwa uchishandisa nzira dzakasiyana siyana. Kurapa kwekupisa kunogona kuvandudza maitiro ayo emagetsi uye kusagadzikana kwekuora, asi kutarisirwa kunoda kutorwa kudzivirira kutsemuka kana deformation inokonzerwa nekupisa kana overcooling. Iine maitiro akanaka ekugadzirisa uye inogona kushandiswa kutendeuka, kugaya, kuchera, kubata uye mamwe mabasa ekugadzirisa. Zvayakaipira ndezvekuti inonamira uye inopisa nekukurumidza, asi iri nyore kuisa jecha pane chero kabhoni simbi uye iri nyore kucheka nesaha.
