Simbi isina ngura ye17-4, inowanzo taurwa nezvayo neAMS 5643, AISI 630, uye UNS S17400, ndeimwe yesimbi dzinonyanya kushandiswa pakugadzirisa mvura. Inozivikanwa nesimba rayo rakasiyana-siyana, inodzivirira ngura zvakanyanya, uye nyore kugadzira, imhando yesimbi inokwanisa kushandiswa mumaindasitiri akasiyana-siyana. Muchinyorwa chino, tichaongorora hunhu, mashandisirwo, uye mabhenefiti esimbi isina ngura ye17-4, kusanganisira kuti nei iri sarudzo inofarirwa nemaindasitiri mazhinji.

Chii chinonzi 17-4 Stainless Steel?

17-4 simbi isina nguraisimbi isina tsvina yakagadzirwa nemartensitic ine 15-17% chromium uye 3-5% nickel. Yakaenzana inoumbwa nesimbi, ine zvimwe zvinhu zvakaita semhangura, molybdenum, uye niobium zvinowedzerwa kuti zviwedzere kunaka kwayo. Inozivikanwa nekusimba kwayo kwakanyanya, kusimba, uye kuramba ngura munzvimbo dzakasiyana-siyana.

Zita rekuti "17-4" rinoreva chimiro chayo, ine 17% chromium uye 4% nickel, izvo zvinoita kuti simbi iyi ive nehunhu hwayo hwakasiyana. Pamusoro pezvo, AMS 5643 specification, AISI 630, uye UNS S17400 zvese zvinoreva chinhu chimwe chete, zvichipa kuenderana kwezviyero zvakasiyana-siyana zvinoshandiswa nemainjiniya nevagadziri pasi rese.

Zvimiro Zvikuru zveSimbi Isina Zvisimbiso 17-4

1. Simba Rakanyanya uye Kuoma
Chimwe chezvinhu zvinonyanya kukosha zvesimbi isingatsvi simbi ye17-4 isimba rayo. Kuburikidza nemaitiro ekupisa anonzi precipitation hardening, alloy iyi inosvika pakusimba kwakasimba kwekusimba, zvichiita kuti ive yakakodzera kushandiswa kwepamusoro-soro. Kana yaoma, simbi isingatsvi simbi ye17-4 inogona kuwana simba rekusimba kusvika ku130 KSI (896 MPa) uye simba rekusimba re160 KSI (1100 MPa).

2. Kuramba Kura Kwakanaka Kwazvo
Nekuda kwehuwandu hwayo hwe chromium yakawanda,17-4 simbi isina nguraInodzivirira ngura zvakanyanya, kunyanya munzvimbo dzine ngura zvishoma. Inoshanda zvakanaka mumamiriro eacidic nealkaline, zvichiita kuti ikodzere kushandiswa kwakasiyana-siyana mumaindasitiri akadai semuchadenga, makemikari, uye petrochemical.

3. Kushandiswa Kwakawanda Mukurapa Kupisa
Kusiyana nedzimwe mhando dzesimbi dzisina ngura, simbi isina ngura 17-4 inogona kugadziriswa nekupisa kuti iwane hunhu hwakasiyana-siyana hwemakanika. Nekugadzirisa tembiricha panguva yekupisa, vagadziri vanogona kugadzirisa kuomarara uye simba rechinhu chacho. Izvi zvinoita kuti chigone kushandiswa zvakasiyana-siyana, kungave muzvikamu zvechivakwa kana munzvimbo dzine kushushikana kwakanyanya.

4. Kugona Kupinza Zvinhu Zvakanaka
Kunyange hazvo simbi dzisina ngura dzemartensitic dzichiwanzova nematambudziko mukusanganisa, simbi dzisina ngura dze17-4 dzinogona kusanganisa zvakanaka kana dzichienzaniswa nedzimwe simbi dziri mukirasi yadzo. Inogona kusanganiswa uchishandisa nzira dzechinyakare, dzakadai segas tungsten arc welding (GTAW), pasina kukanganisa simba rayo kana kuramba kwayo ngura. Zvisinei, kurapwa kwakakodzera kwekupisa mushure mekusanganisa kunokurudzirwa kuchengetedza hunhu hwayo hwakanaka.

5. Nyore yeKugadzira Machining
Imwe mukana wesimbi isingatsvi 17-4 ndeyekuti iri nyore kugadzira. Kunyange zvazvo yakaoma, ichiri nyore kugadzira uchishandisa matekiniki echinyakare ekugadzira, zvichiita kuti maumbirwo akaomarara nemagadzirirwo agadziriswe zvinobudirira. Chinhu ichi chinoita kuti ibatsire zvikuru vagadziri vanoda kunyatsogadzira zvinhu zvavo.

Mashandisirwo eSimbi Isina Kusimba 17-4

Hunhu hwakasiyana hwesimbi isingatsvedzeri ye17-4 hunoita kuti ikwanise kushandiswa kwakasiyana-siyana. Mamwe emaindasitiri anonyanya kushandiswa anoshandisa simbi isingatsvedzeri ye17-4 anosanganisira:

• Ndege neNdege
  Simbi isingasvibi 17-4 isarudzo yakakurumbira muindasitiri yendege nekuda kwekusimba kwayo kukuru, hunhu hwayo hwakareruka, uye kuramba ngura. Inowanzoshandiswa mukugadzira mapanga e turbine, mapanga e compressor, shafts, uye zvikamu zvemaumbirwo endege.

• Maindasitiri eMakemikoro nePetrokemikari
  Kusabatwa nengura kunoita kuti simbi isingatsvi 17-4 ive sarudzo yakanaka yemidziyo inobatwa nemakemikari akaomarara nenzvimbo dzakaoma, kusanganisira mavharuvhu, mapombi, uye midziyo yekumanikidza. Inogona kutsungirira nguva refu ikabatwa nezvinhu zvine acidic nealkaline, ichichengetedza kunaka kwayo uye kushanda kwayo.

• Zvishandiso Zvekurapa
  Mukurapa, simbi isingatsvedzi ye17-4 inoshandiswa mukugadzira zvishandiso zvekuvhiya, maimplants, uye michina. Kuenderana kwayo nezvinhu zvipenyu, pamwe chete nesimba rayo guru uye kuramba kwayo ngura, kunoita kuti ive chinhu chakakodzera kushandiswa mukurapa kunoda kugara kwenguva refu uye hutsanana.

• Zvikumbiro zveMarine neOffshore
  Kusagona kwesimbi iyi kurwisa ngura yemvura ine munyu kunoita kuti ikodzere kushandiswa munzvimbo dzegungwa, uko zvinhu zvine simba guru zvinodiwa pazvinhu zvakaita semapropeller shafts, mapombi, uye zvinosunga.

• Midziyo yeMaindasitiri
  Simbi isingatsvi 17-4 inoshandiswawo mumichina yakasiyana-siyana yemaindasitiri, kusanganisira magiya, shafts, uye mavharuvhu, uko simba uye kuramba ngura zvakakosha. Kugona kwayo kuita zvinhu zvakasiyana-siyana uye mashandiro ayo zvinoita kuti ive sarudzo yakanaka munzvimbo idzi dzine kushushikana kwakanyanya.

Mabhenefiti ekusarudza 17-4 Stainless Steel

1. Kugara Kwakasimba uye Kushanda Kwakavandudzwa
Nekuda kwemusanganiswa wayo unoshamisa wesimba, kuomarara, uye kuramba ngura,17-4 simbi isina ngurainowedzera hupenyu hwezvinhu zvinoshandiswa mukushandiswa kwakaoma. Zvikamu zvakagadzirwa nesimbi isingatsvi 17-4 hazviwanzo kukuvara, ngura, kana kuneta, zvichiita kuti basa rive refu uye mari yekugadzirisa iderere.

2. Imwe nzira inoshanda pamutengo wakaderera
Kunyange hazvo alloys dzesimbi dzisingatsvinda dzichigona kudhura, simbi isingatsvinda ye17-4 inopa mhinduro inodhura zvishoma nekupa mashandiro epamusoro pamutengo unokwikwidzana. Kana tichifunga nezvehupenyu hwese uye zvinodiwa zvekugadzirisa zvishoma, zvinoratidza kuti isarudzo yezvinhu zvine chekuita nemutengo kune maindasitiri mazhinji.

3. Kugadzirisa Zviri Nyore
Nekukwanisa kwayo kupisa zvinhu zvakati, simbi isingatsvi 17-4 inopa mwero wekugadzirisa zvinhu izvo zvimwe zvinhu zvisingagoni kuenzana nazvo. Kuchinjika uku kunobvumira vagadziri kugadzirisa zvinhu kuti zvienderane nezvinodiwa zvakasimba zvesimba uye kugara kwenguva refu zvemapurojekiti chaiwo.

Mhedziso

Simbi isina ngura ye17-4 (AMS 5643, AISI 630, UNS S17400) chinhu chinoshandiswa zvakasiyana-siyana uye chakavimbika chinopa chiyero chakakwana chesimba rakakwirira, kuramba ngura, uye nyore kugadzira. Ungave uchishanda mundege, kugadzira makemikari, kana chero imwe indasitiri inoshanda zvakanyanya, chisanganiswa ichi chakagadzirirwa kusangana nezvinodiwa zvakanyanya.Simbi Yakanaka, tinodada nekupa zvinhu izvi zvemhando yepamusoro, tichiona kuti mapurojekiti enyu anobatsirwa nezvakanakisa muindasitiri iyi.

Nehunhu hwayo hwepamusoro uye akasiyana-siyana emashandisirwo,17-4 simbi isina nguraichiri sarudzo inonyanya kufarirwa nemainjiniya nevagadziri vari kutsvaga mhinduro yakavimbika uye inogara kwenguva refu yekushandiswa kwavo kwakakosha.
