1. Mechanical Properties yeStainless Steel
Inodiwa ma mechanical properties inowanzo pihwa mukutenga zvinotemerwa zvestainless simbi. Minimum mechanical zvivakwa zvinopihwawo neakasiyana mazinga anoenderana nechinhu uye chigadzirwa fomu. Kusangana neaya akajairwa emuchina zvivakwa zvinoratidza kuti zvinhu zvakagadzirwa nemazvo kune yakakodzera mhando system. Mainjiniya vanogona kuzoshandisa nechivimbo izvo zvinhu muzvimiro zvinosangana nemitoro yekushanda yakachengeteka uye nekumanikidza.
Mechanical zvivakwa zvinotsanangurwa kune akafuratira akakungurutswa zvigadzirwa anowanzo kusimba simba, goho kushushikana (kana chiratidzo kushushikana), elongation uye Brinell kana Rockwell kuoma. Zvivakwa zvinodikanwa zvebha, chubhu, pombi uye mafittings anowanzo taura kusimba kwekusimba uye goho kushushikana.
2. Goho Simba reStainless Steel
Kusiyana nesimbi dzakapfava, kusimba kwegoho reannealed austenitic Stainless simbi chikamu chakaderera kwazvo chekusimba kwesimba. Simba rakapfava regoho resimbi rinowanzoita 65-70% yesimba rekusimba. Huwandu uhu hunowanzoita 40-45% chete mumhuri yeaustenitic stainless.
Kutonhora kushanda nekukurumidza uye kunowedzera zvakanyanya simba regoho. Mamwe mafomu esimbi isina tsvina, sewaya yechirimo, anogona kutonhora kushanda kusimudza goho resimba kusvika 80-95% yesimba rekusimba.
3. Ductility yeStainless Steel
Iko kusanganiswa kweakakwira basa kuomesa mazinga uye yakakwirira kureba / ductility inoita kuti simbi isina tsvina ive nyore kugadzira. Nekusanganiswa kwepfuma uku, simbi isina tsvina inogona kuremara zvakanyanya mukushanda sekunge kudhirowa kwakadzika.
Ductility inowanzoyerwa se% kureba kusati kwatsemuka panguva yekuyedzwa kwekunetseka. Annealed austenitic Stainless simbi dzine kureba kwakasiyana-siyana. Nhamba dzakajairika ndeye 60-70%.
4. Kuoma kweStainless Steel
Kuoma ndiko kupikisa kupinda kwechinhu chepamusoro. Hardness testers inoyera kudzika kwekuti indenter yakaoma kwazvo inogona kusundirwa mukati mechinhu. Brinell, Rockwell uye Vickers michina inoshandiswa. Imwe neimwe yeiyi ine yakasarudzika yakaumbwa indenter uye nzira yekushandisa inozivikanwa simba. Shanduko pakati pezviyero zvakasiyana saka ingori fungidziro chete.
Martensitic uye kunaya kunoomesa mamakisi zvinogona kuomeswa nekurapa kwekupisa. Mamwe mamakisi anogona kuomeswa kuburikidza nekushanda kunotonhora.
5. Kusimba Kwesimba reStainless Steel
Kusimba kwesimba kazhinji ndiyo yega midziyo yemagetsi inodiwa kutsanangura bhawa uye waya zvigadzirwa. Magiredhi akafanana ezvinyorwa anogona kushandiswa pamasimba akasiyana-siyana ekushandisa zvakasiyana zvachose. Iyo inopihwa tensile simba rebar uye waya zvigadzirwa zvine chekuita nekushandiswa kwekupedzisira mushure mekugadzira.
Spring wire inowanzova nepamusoro-soro yakasimba simba mushure mekugadzira. Simba repamusoro rinopihwa nekutonhora kushanda muzvitubu zvakasungwa. Pasina simba rakakwirira iri waya yaisashanda zvakanaka sechitubu.
Kusimba kwakakwirira kwakadaro hakudiwi kuti waya ishandiswe mukugadzira kana kuruka nzira. Waya kana bhara rinoshandiswa sezvimedu zvekusungirira, semabhaudhi nema screws, zvinoda kuve zvakapfava zvekuti musoro neshinda zviumbwe asi zviine simba zvekukwanisa kuita basa rakakwana.
Mhuri dzakasiyana dzesimbi isina tsvina dzinowanzove nekusimba kwakasiyana uye kuburitsa simba. Aya akajairwa masimba ezvinyorwa zvakanyungudutswa anotsanangurwa muTafura 1.
Tafura 1. Yakajairika simba re annealed Stainless simbi kubva kumhuri dzakasiyana
| Tensile Simba | Goho Simba | |
| Austenitic | 600 | 250 |
| Duplex | 700 | 450 |
| Ferritic | 500 | 280 |
| Martensitic | 650 | 350 |
| Kunaya Kuoma | 1100 | 1000 |
6. Zvinhu Zvenyama zveStainless Steel
● Corrosion resistance
● Kudzivirira kwepamusoro uye kuderera kwekushisa
● Kureruka kwekugadzira
● Simba Rakakwirira
● Runako runokwezva
● Utsanana uye nyore kuchenesa
● Hupenyu hurefu
● Inogona kushandiswazve
● Low magnetic permeability
7. Corrosion Resistance yeStainless Steel
Good corrosion resistance inhengo yesimbi dzese dzisina tsvina. Low alloy mamakisi anogona kuramba corrosion mumamiriro akajairwa. Yepamusoro alloys inodzivirira kuora neakawanda acids, alkaline mhinduro uye chloride nharaunda.
Kupokana kwekuora kwesimbi isina tsvina kunokonzerwa nechromium yavo. Kazhinji, simbi isina simbi ine hushoma hunosvika 10.5% chromium. Iyo chromium mu alloy inoumba inozviporesa inodzivirira yakajeka oxide layer inoumba yega mumhepo. Iyo yekuzviporesa hunhu hweiyo oxide layer inoreva kuti kuramba kwecorrosion kunoramba kwakasimba zvisinei nemaitiro ekugadzira. Kunyangwe iyo nzvimbo yepasi ikachekwa kana kukuvadzwa, inozvirapa yega uye kuramba kwecorrosion kunochengetedzwa.
8. Kunyanya Temperature Resistance
Mamwe mamakisi esimbi asina tsvina anogona kuramba kuyera uye kuchengetedza simba repamusoro pakupisa kwakanyanya. Mamwe magiredhi anochengetedza akakwira ma mechanical zvivakwa pane cryogenic tembiricha.
Kusimba Kwakakwirira Kwesimbi isina Stainless
Magadzirirwo ezvikamu uye nzira dzekugadzira dzinogona kuchinjwa kuti dzitore mukana wekuomeswa kwebasa resimbi isina tsvina inoitika kana ichitonhora yakashanda. Mhedzisiro yakakwira masimba anogona kubvumira kushandiswa kwezvinhu zvakatetepa, zvichiita kuti uremu hwakaderera uye mutengo.
Jindalai Steel Group ndiyo inotungamira Mugadziri & Exporter yesimbi isina tsvina coil/sheet/plate/strip/pipe. Irikusangana neanopfuura makore makumi maviri ebudiriro mumisika yepasirese uye parizvino ine mafekitori maviri ane huwandu hwekugadzira hunodarika mazana mana ezviuru ematani pagore. Kana iwe uchida kuwana rumwe ruzivo nezve Stainless simbi zvinhu, unogamuchirwa kutibata nesu nhasi kana kukumbira quote.
