Tsananguro pfupi:
Simbi isina ngura ye440C isimbi isina ngura ine kabhoni yakawanda inozivikanwa nekuoma kwayo, kuramba kupera, uye kuramba ngura.
Simbi Isina Kushanda 440C Mabhawa:
Simbi isingatsvedzeri ye440C inogona kuomeswa kuti iome zvakanyanya, kazhinji inenge 58-60 HRC (Rockwell hardness scale). Ndiyo ye400 series yesimbi dzisingatsvedzeri, idzo dzine huwandu hwakawanda hwekabhoni, kazhinji inenge 0.60-1.20%, uye inodzivirira ngura zvine mwero. Ine simba rakanaka rekupfeka, zvichiita kuti ikodzere kushandiswa senge mabheyaringi, maturusi ekucheka, zvishandiso zvekuvhiya, uye zvikamu zvevharuvhu. Kunyange zvazvo isina simba rekuora sesimbi dzisingatsvedzeri dzeaustenitic (semuenzaniso, 304, 316), 440C inopa simba rakanaka rekuora munzvimbo dzakapfava. Inodzivirira ngura kupfuura dzimwe simbi dzine kabhoni yakawanda nekuda kwehuwandu hwayo hwechromium.440C simbi isingatsvedzeri inogona kugadziriswa nekupisa kuti iwane hunhu hwemakanika hwaunoda.

Zvimiro & Mabhenefiti:
•Mushure mekupiswa kwakakodzera, simbi isingatsvi ye440C inogona kuoma zvakanyanya, kazhinji pakati pe58-60 HRC, zvichiita kuti ive yakakodzera kushandiswa kunoda kuoma kwakanyanya.
•Nekuda kwehuwandu hwayo hwekabhoni yakawanda uye hunhu hwakanaka hwekurapa kupisa, simbi isingatsvedzi ye440C inoratidza kusakara kwakanaka, zvichiita kuti ikodzere kushandiswa kwakasiyana-siyana senge maturusi ekucheka, mabheyaringi, nezvimwewo.
•Kunyange zvazvo isina ngura sesimbi dzisingatsvinyike dzinoshandiswa mukugadzira (semuenzaniso, 304, 316), simbi isingatsvinyike ye440C ichiri kuramba ngura zvakanaka munzvimbo dzakakodzera, kunyanya nekuda kwehuwandu hwayo hwakawanda hwechromium, iyo inoumba chromium oxide surface layer inodzivirira.
•Simbi isingatsvi ye440C inogona kugadzirwa nemachina nemazvo pasi pemamiriro akakodzera kuti isangane nezvinodiwa zvakasiyana-siyana zvezvikamu. Zvisinei, nekuda kwekuoma kwayo uye simba rayo, kugadzira kunogona kuoma uye kunoda mashandisirwo akakodzera ekugadzira nematurusi.
•Simbi isingatsvi ye440C inoratidza kugadzikana kwakanaka pakupisa kwepamusoro, ichichengetedza kuoma kwayo uye kuramba kwayo kusingapfeki mumamiriro ekupisa akakwira, zvichiita kuti ikodzere kushandiswa munzvimbo dzinopisa zvakanyanya.
•Hunhu hwesimbi isingatsvi ye440C hunogona kugadziriswa kuburikidza nekupisa, sekuomarara, kusimba, uye kuomarara, kuti zvienderane nezvinodiwa zvekushandisa.
Sei Uchifanira Kusarudza Isu?
•Unogona kuwana zvinhu zvakakwana zvinoenderana nezvaunoda nemutengo wakaderera.
•Tinopawo mitengo yekutumira zvinhu pasuo nesuo, FOB, CFR, CIF, uye yekutumira zvinhu pasuo nesuo. Tinokukurudzira kuti uite dhiri rekutumira zvinhu iro richave rakachipa.

Chii chinonzi 440C Stainless Steel?
Simbi isingatsvi ye440C inopa mwero wekudzivirira kupfekwa zvakanaka uye kudzivirira kupfekwa kuri pakati nepakati munzvimbo dzakapfava, nekuomarara kwakanaka. Inofanana ne440B grade asi ine kabhoni yakakwira zvishoma, zvichikonzera kuomarara kwakanyanya asi kudzivirira kupfekwa kuri kuderera zvishoma zvichienzaniswa ne440B. Inogona kuwana kuomarara kusvika ku60 Rockwell HRC uye inodzivirira kupfekwa munzvimbo dzakajairika dzemumba nedzemaindasitiri, nekuomarara kwakanyanya kunowanikwa pasi pe400°C tembiricha yekudziya. Kugadzirira pamusoro kwakakosha kuti idzivirire kupfekwa zvakanaka, zvichiita kuti zvikwanise kubviswa zvikero, mafuta ekuzora, zvidimbu zvekunze, uye machira. Kuoma kwayo kwakanyanya kwekabhoni kunobvumira kugadzirwa kwakafanana nesimbi inokurumidza kunyungudutswa.
440C Stainless Steel Round Bar Kushandiswa:
Matavi akatenderera esimbi isina ngura e440C anoshandiswa zvakanyanya mukugadzira mapanga, mabheyaringi, maturusi ekushandisa nekucheka, zvishandiso zvekurapa, zvikamu zvevharuvhu, uye michina yeindasitiri, uko kuomarara kwazvo, kuramba kupfeka, uye kuramba ngura zvine mwero zvinoita kuti zvive sarudzo dzakanakira zvikamu zvakakosha zvinoda kushanda zvakanaka uye kugara kwenguva refu.
Kukwesha kweSimbi Isina Kushanda 440C：
Nekuda kwekuoma kwayo kwakanyanya uye nyore kwayo kuomesa mhepo, kupinza simbi isingatsvedzi ye440C hakuwanzoitiki. Zvisinei, kana kupinza simbi, zvinokurudzirwa kuti chinhu chacho chipiswe kusvika pa260°C (500°F) uye kuita mushonga wekupisa mushure mekupinza simbi pa732-760°C (1350-1400°F) kwemaawa matanhatu, zvichiteverwa nekutonhodza vira zvishoma nezvishoma kudzivirira kutsemuka. Kuti uve nechokwadi chekuti zvinhu zvakafanana mukubatanidza simbi zvakafanana, kupinza simbi zvine chimiro chakafanana zvinofanira kushandiswa. Neimwe nzira, AWS E/ER309 inogonawo kutariswa sesarudzo yakakodzera.
