Nzira yekuziva sei kunaka kwesimbi isina tsvina yakarukwa tsvimbo / tambo yakarukwa / stud bolt?

1. Magnetic kuonekwa

Wati simbi isina magineti, handiti! Ichokwadi zvakare kuti haisi magnetic! Kutaura zvazviri, vakatosiyana. Isu tese tinoziva kuti Stainless simbi yakakamurwa kuita austenitic Stainless simbi uye ferritic Stainless simbi. Austenitic Stainless simbi haisi-magnetic, nepo ferritic Stainless simbi isimbi yakasimba yemagineti. Kuburikidza nenhevedzano yezviyedzo, zvinoratidzwa kuti austenitic simbi isina tsvina ichave neasinganzwisisike magineti pasi pemamwe mamiriro akakosha, asi isiri-magnetic mumamiriro ezvinhu akajairwa.

2. Ita nitric acid point test

Muzviitiko zvakawanda, zvakaoma kusiyanisa 200 series, 300 series, 400 series uye mamwe marudzi esimbi isina tsvina neziso rakashama. Iyo nitric acid point bvunzo ndiyo yakanyanya intuitive bvunzo nzira yekuyedza corrosion kuramba kweiyo substrate. Kazhinji, mazana mana akatevedzana anongove nemarara zvishoma panguva yekuyedzwa, nepo mazana maviri akateedzana simbi isina tsvina ine yakaderera corrosion resistance ichange iine corrosion marks.

3. Kuoma bvunzo

Kana austenitic Stainless simbi icharatidza mamwe magineti kana ichitonhora ichikungurutswa pasi pemhepo yemhepo, ipapo yekutanga magineti bvunzo ichangobva kutaurwa haishande; saka tinoda kupisa simbi isina simbi kusvika 1000-1100 ℃ uye toidzima nemvura kuti ibvise magineti eaustenitic simbi isina tsvina uye kuyedza kuomarara. Kuoma kwe austenitic simbi isina tsvina kunowanzova pasi peRB85

Pamusoro pe

Hukukutu hwe430, 430F uye 466 simbi ishoma pane Rc 24.

Kuoma kwe410, 414, 416 uye 431 ndiko Rc36~43

Kuomarara kwekabhoni yepamusoro 420, 420F, 440A, B, C uye F simbi ndeye Rc50~60

Kana kuoma kuri Rc50 ~ 55, inogona kunge iri 420 simbi

Kuomarara kweakadzima 440A uye B samples ndeye Rc55 ~ 60

Iyo Rc kukosha kwe60 kana pamusoro i440C simbi.

4. Kuburikidza nekuongorora kwemuchina

Kana iyo simbi isina simbi iri kuedzwa yakaita shaft-shaft, zvinokurudzirwa kuti uende nayo kune yakajairwa lathe kana CNC lathe yekuongorora machining, asi pachine zvisingakwanisi. Iyi nzira inokodzera simbi iri nyore kutema uye yakajairwa simbi isina tsvina, yakadai se303, 416, 420F, 430F, 440F. Mhando yesimbi inozivikanwa nechimiro chekuchinja machipisi. Mhando iyi yesimbi iri nyore-kutema inobudisa kunhuhwirira kusingafadzi kana ichishandurwa munzvimbo yakaoma.

5. Phosphoric acid kuona

Iyi inzira yekuona yatinoshandisa kakawanda muhupenyu hwezuva nezuva. Iyi nzira inoshandiswa kusiyanisa chromium-nickel simbi isina tsvina. Wedzera concentrated phosphoric acid kune 0.5% sodium fluoride solution uye kupisa kusvika 60-66 ℃.

6. Kuonekwa nemhangura sulfate point

Iyi nzira inogona kuona yakajairwa kabhoni simbi uye simbi isina tsvina. Iko kusanganiswa kwemhangura sulfate mhinduro inofanira kuva pakati pe5% ne10%. Kana yakadonhedzwa pasimbi kuti iedzwe, simbi yemhangura inoumbwa pamusoro peyakajairwa kabhoni simbi mukati memasekonzi mashoma, nepo pamusoro pesimbi isina tsvina inoramba isina kushanduka.

7. Sulfuric acid solution yekuona

Iyi nzira inogona kusiyanisa 302, 304, 316, uye 317 simbi isina tsvina. Gadzirira sulfuric acid ine huwandu hwe20% kusvika 30% uye tembiricha inenge 70 ° C, uye isa simbi kuti iedzwe mumhinduro. 302 uye 304 simbi isina tsvina inoburitsa huwandu hukuru hwemabhuru pavanosangana nemhinduro uye inoshanduka dema mukati memaminitsi mashoma;

Kusiyana neizvi, 316 uye 317 simbi isina tsvina hairatidze kuita kwakakura mumhinduro, uye zvakanyanya haiite dema mukati megumi kusvika gumi nemashanu maminetsi.

8. Cold acid point yekuona

Rudzi rumwe chete rwesimbi isina tsvina inogona kusiyaniswa nekudonhedza 20% sulfuric acid solution pamusoro pesample iyo yakavhuniwa, yakakwenenzverwa, yakacheneswa kana kukwenenzverwa.

Donhedza madonhwe mashoma emushonga weasidhi pamusoro pemuenzaniso wega wega. Pasi pechiito chemhinduro yeasidhi, 302 uye 304 simbi dzisina tsvina dzakasvibiswa zvakasimba uye dzinoshanduka dema, dzichiratidza shava-dema kana dema, uye ipapo makristasi egirini anoumbwa mumhinduro;

316 simbi isina tsvina inoora zvishoma nezvishoma uye zvishoma nezvishoma inoshanduka tsvuku-yero, yobva yaita dema-dema, uye pakupedzisira inoumba mamwe akajeka makristasi matema mumhinduro; Kuita kwepamusoro kwe317 simbi isina tsvina kunowedzera zvishoma nezvishoma.

9. Kucherechedza kuburikidza nepfarivari

Iyo spark bvunzo inoshandiswa kusiyanisa kabhoni simbi, dhizaini alloy simbi uye chishandiso simbi, asi haina basa shoma mukusiyanisa simbi isina tsvina. Iyi spark test nzira inogona kubatsira vane ruzivo vanoshanda kurongedza simbi isina tsvina muzvikamu zvina zvikuru, asi hazvisi nyore kusiyanisa pakati pemagiredhi esimbi akasiyana.

Iyo hunhu spark inoti yeaya mapoka mana eStainless simbi michina ndeaya anotevera:

Kirasi A: 302, 303, 316 simbi, ichigadzira mapfupi matsvuku madiki ane maforogo akati wandei.

Kirasi B: 308, 309, 310 uye 446 simbi, ichigadzira mashoma mashoma mapfupi matsvuku akasviba ane maforogo akati wandei.

Kirasi C: 410, 414, 416, 430 uye 431 simbi, ichigadzira twumira twurefu chena nemaforogo akati wandei.

Kirasi D: 420, 420F uye 440A, B, C, F, ichiburitsa twumoto twuruvara tunopenya nekupenya kuri pachena kana twumirangarara twakareba.

10. Kuburikidza nehydrochloric acid yekuona

Iyi nzira yekuona inogona kusiyanisa 403, 410, 416, 420 simbi isina tsvina ine yakaderera chromium zvirimo kubva pa430, 431, 440, 446 simbi isina tsvina ine yakakwira chromium zvirimo.

Dissolve zviyero zvakaenzana zvezvicherwa zvemuenzaniso mune hydrochloric acid mhinduro ine vhoriyamu density ye50% kwemaminitsi matatu, uye enzanisa kusimba kwemavara emhinduro. Simbi ine chromium yakakwira ine ruvara rwakasvibira.
