321 simbi isina tsvina 4.0 * 0.35 mm yakakoswa chubhu
321 is a titanium yakagadzikana chromium-nickel austenitic stainless simbi ine simba rakanaka uye yakanakisa corrosion resistance, seinopihwa mu annealed condition ine yakajairika brinell kuomarara kwe175. maajenti, chikafu chakajairwa, zvigadziriso zvinouraya, madhayi, makemikari mazhinji emakemikari pamwe neakasiyana siyana emakemikari emusikirwo, zvakare inopisa peturu magasi, gasi rinopisa, nitric acid, uye kusvika pamwero mudiki sulfuric acid.Iyo inoratidzira yakanaka oxidation kuramba patembiricha yakakwira ine yakanyanya kupikisa kune intergranular corrosion uye ine yakanakisa weldability.321 haigone kuomeswa nekurapa kwekupisa, asi simba nekuomarara zvinogona kuwedzerwa zvakanyanya nekushanda kunotonhora, nekuzodzikisira kunotevera kwekuita ductility.
Inoshandiswa zvakanyanya pamashandisirwo apo kuwedzera kwetitanium uye kudzikamisa kwayo sechinhu chekugadzira carbide inobvumira kuti isungirwe uye / kana kushandiswa mukati meiyo carbide mvura inonaya 430.oC - 870oC pasina njodzi ye intergranular corrosion.Izvi zvinosanganisira Kugadzira Chikafu, Dairy Equipment, Chemical, Petrochemical, Transport uye akabatana maindasitiri nezvimwe.
Material asiri magineti mune yakavharwa mamiriro, asi anogona kuita zvinyoro magineti zvichitevera kutonhora kwekushanda.
Anealing inodiwa kugadzirisa kana zvichidikanwa.
NB Optimum corrosion resistance inowanikwa mune annealed mamiriro.
