Kuumbwa uye Zvivakwa zve409 Stainless Simbi

409 Stainless steel steel isimbi yakajairwa ferritic simbi inoshandiswa mumichina, kuvaka, uye zvimwe zvikumbiro zveinjiniya. Pamusana pekuvapo kwezviyo zve austenite, maitiro ayo emagetsi anovandudzwa zvikuru, uye simba rayo uye kuoma zvinowedzerwawo zvakanyanya nekuda kwekuwedzera kwezvinhu zvakawanda zvealloying. Mune ino post, ngatitarisei zvakanyanya pane iyo kuumbwa uye zvivakwa zve 409 simbi isina tsvina.

Kemikari Inoumbwa ye409 Stainless Simbi

Mushonga wemakemikari we409 simbi isina tsvina unoisiyanisa kubva kune mamwe marudzi esimbi isina tsvina. Inonyanya kuumbwa nesimbi uye ine chromium yakawanda uye zviduku zvekabhoni, manganese, silicon, uye nitrogen.

Simbi ndiyo chinhu chikuru mu409 simbi isina tsvina, ichichipa simba uye kugadzikana. Chromium inopa alloy corrosion resistance uye inobatsira kugadzira inodzivirira oxide layer pamusoro. Carbon inobatsira mukuvandudza kuomarara kwechinhu uye kupfeka kuramba.

Manganese inogona kuita seyakagadzikana, kudzivirira yakawandisa zviyo kukura panguva yekupisa kurapwa. Silicon inokwidziridza iyo oxidation kuramba uku ichideredza kuyera pakupisa kwakanyanya. Nitrogen inonatsiridza ma mechanical properties senge tensile simba uye goho simba.

Iyi yakasarudzika musanganiswa wezvinhu inopa 409 simbi isina tsvina yakanakisa yekuwedzera kupisa zvivakwa, zvichiita kuti ive yakakodzera kune yakakwirira-tembiricha maapplication pasina kukanganisa kusimba kwayo kwechimiro kana kugadzikana kwedimensional. Kuumbwa kwayo kwemakemikari kunopawo zvakanaka weldability, kurerutsa maitiro ekugadzira.

Kunzwisisa kuumbwa kwekemikari ye409 simbi isina tsvina kwakakosha pakuona kukodzera kwayo kune chaiyo maapplication, uko zvinhu zvakaita sekudzivirira kupisa uye kushomeka kwemarara zvinoda kutariswa.

Zvivakwa zve409 Stainless Simbi - Heat Resistance

The kupisa kupisa kwe409 simbi isina tsvina ndeimwe yeakakosha maitiro anoita kuti ive sarudzo yakakurumbira kune akasiyana maapplication. Iri giredhi resimbi isina tsvina rinogona kumira tembiricha yakakwira pasina kurasikirwa nechimiro chayo chechimiro kana kusangana nedeformation.

Kupisa kwekupisa kwe409 simbi isina tsvina kunogona kuverengerwa kumakemikari ayo, ayo ane chromium yakawanda uye shoma kabhoni. Kuvapo kwechromium kunoumba inodzivirira oxide layer pamusoro, inozivikanwa sepassivation film, iyo inobatsira kudzivirira oxidation uye corrosion pakupisa kwakanyanya.

Pamusoro pekupisa kwayo kwakanyanya kupisa, 409 simbi isina tsvina inoratidzawo yakanaka yekupisa conductivity. Izvi zvinoreva kuti inogona kunyatso kuitisa kupisa kure nekupisa, nekudaro ichidzikisa njodzi yekupisa uye kukuvara kunogona kuitika.

Uyezve, nekuda kweiyo ferritic microstructure, giredhi iyi inochengetedza simba rayo kunyangwe pakupisa kwakanyanya. Ferritic Stainless steels vanozivikanwa nekugona kwavo kuchengetedza mechanical zvivakwa pasi pekupisa kwakanyanya.

Nezvizvi zvinokatyamadza zvekudzivirira kupisa, 409 simbi isina tsvina inoshandiswa zvakanyanya mumotokari uye marori epoust masisitimu, uko inoburitswa nekupisa kwakanyanya kunogadzirwa nemagetsi emagetsi emagetsi. Inoshandiswawo muchoto cheindasitiri, kupisa zvinhu, uye zvimwe zvinhu zvinoda kushanda kwakavimbika pakupisa kwakanyanya.

Zvivakwa zve409 Stainless Simbi - Corrosion Resistance

Corrosion kuramba chinhu chakakosha chekufunga nezvazvo pakusarudza simbi isina tsvina kune akasiyana maapplication. Panyaya ye409 simbi isina tsvina, inoratidza kumira zvakanaka kwekuora munzvimbo dzakawanda.

Chimwe chezvikonzero zvekupokana kwayo necorrosion ndeye yakakwira chromium yemukati. Chromium inoumba inodzivirira oxide layer pamusoro pesimbi iyo inoshanda sechipinganidzo kurwisa zvinhu zvinoparadza zvakaita semwando nemakemikari. Iyi oxide layer inobatsira kudzivirira ngura uye inowedzera hupenyu hwesevhisi.

Imwe mukana we409 simbi isina tsvina ndeyekupokana kwayo nekunetseka-kuora kutsemuka. Rudzi urwu rwekuora runoitika kana kusagadzikana kuripo uye mamiriro ezvakatipoteredza akadai sekuratidzwa kune chlorides kana sulfides aripo. Iyo yakasarudzika kuumbwa kwe409 simbi isina tsvina inoita kuti ive yakanyanya kupikisa kune iyi fomu yekukuvadza.

Pamusoro pezvo, 409 simbi isina simbi ine yakanakisa mumhepo corrosion resistance, ichiita kuti ive yakakodzera kune zvekunze zvikumbiro zvinogona kuoneswa nemamiriro ekunze asina kunaka. Inogona kumira kuratidzwa kwenguva refu kune hunyoro, munyu wekupfapfaidza, uye zvimwe zvinokuvadza zvinowanzoitika munzvimbo dzekunze.

Nekupokana kwayo kwakasimba kwekuora, 409 simbi isina tsvina yakaratidza kuti isarudzo yakavimbika kune akasiyana maindasitiri anoda kuchengetedzwa kubva mukuora, senge mota epoust masisitimu, catalytic converters, heat exchangers, uye mamwe akasiyana maapplication anogona kuoneswa kune corrosion mamiriro.

mhedziso

Ndatenda nekuverenga chinyorwa chedu uye tinovimba chinogona kukubatsira kuti uve nekunzwisisa kuri nani kwe kuumbwa uye zvivakwa zve 409 simbi isina tsvina. Kana iwe uchida kuwana rumwe ruzivo nezve 409 Stainless Steel, tinoda kukuraira kuti ushanyire Sino Stainless Steel.

Semutengesi anotungamira wezvigadzirwa zvesimbi 409 pasi rose, Sino Stainless Steel inopa vatengi nemhando yepamusoro 201 Stainless Steel Strip & 304 Stainless Steel Strip, 409 Stainless Steel, 316 uye 316L Stainless Simbi, Stainless Steel Hexagon Bars, Kupisa-yakakungurutswa Stainless Steel Coils, Colored Stainless Steel Sheets, Simbi isina ngura Perforated Sheets, Stainless Simbi Angle Mabhawa, Cold-rolled Precision Stainless Steel Strips, Isimbi Yesimbi, uye Embossed Stainless Steel Plates pamutengo wakakwikwidza zvikuru.
