Chii chinonzi Stainless steel?
Stainless simbi zvinhu hazvisi chete zvakajairika muhupenyu hwedu hwezuva nezuva, asi zvakare zvakashandiswa zvakanyanya muindastiri inorema, indasitiri yakareruka uye maindasitiri ekuvaka. Stainless acid-resistant steel inonzi simbi isina tsvina. Inoumbwa nesimbi isina tsvina uye acid-resistant simbi. Muchidimbu, simbi inokwanisa kurwisa ngura yemuchadenga inodaidzwa kuti simbi isina tsvina, uye simbi inokwanisa kuramba kuparara kwemakemikari media inodaidzwa kuti acid-resistant simbi. Idzi dzinowanzo shandiswa Stainless simbi mhando 304, 304L, 316, 316L, ari mazana matatu akatevedzana masimbi eaustenitic simbi isina tsvina. 304, 304L, 316, 316L zvinorevei? Kutaura zvazviri, izvi zvinorevaStainless simbi mureza simbi giredhi, zviyero zvenyika dzakasiyana zvakasiyana, ndapota tarisa kune tafura inotevera kuti uwane ruzivo.
304simbi isina ngura
304 simbi isina tsvina isimbi yepasirese uye inoshandiswa zvakanyanya ine yakanaka corrosion resistance, heat resistance, low-temperature simba uye mechanical properties; kushanda zvakanaka kwekugadzirisa uye kusimba kwepamusoro. Inoshandiswa zvakanyanya kugadzira michina uye zvikamu zvinoda kuita kwakanaka kwakazara (corrosion resistance uye formability). Inoshingirira mukuora mumhepo. Kana iri mhepo yeindasitiri kana kuti nzvimbo yakasvibiswa zvakanyanya, inoda kucheneswa nenguva kuti isaita ngura. Inoshingirira mukuora mumhepo. Kana iri mhepo yeindasitiri kana kuti nzvimbo yakasvibiswa zvakanyanya, inoda kucheneswa nenguva kuti isaita ngura. 304 Stainless simbi inozivikanwa munyika yose chikafu-giredhi Stainless simbi.
316simbi isina ngura
Musiyano mukuru pakati pe316 ne304 mukugadzirwa kwemakemikari ndeyekuti 316 ine Mo, uye inowanzozivikanwa kuti 316 ine nani kusvibiswa kwekudzivirira uye inopesana nekuora mumamiriro ekupisa kwepamusoro kupfuura 304. Inogona kushandiswa pasi pehutsinye hwepamusoro-tembiricha. mamiriro; basa rakanaka kuomesa (rakaneta kana risiri-magineti mushure mekugadzirisa); isiri-magnetic mune yakasimba mhinduro mamiriro; kuita zvakanaka welding. Yakasiyana-siyana yekushandiswa, senge makemikari, dhayi, bepa, oxalic acid, fetiraiza uye zvimwe zvigadzirwa zvekugadzira, indasitiri yechikafu, zvivakwa munzvimbo dzemahombekombe, zvakakoshaStainless steel filtersetc.
"L"
Sezvatinoziva tose, Stainless simbi ine zvinhu zvakasiyana-siyana, uye simbi ine yakaderedzwa carbide zvirimo kupfuura zvakazara zvichange zvichiratidzwa nekuwedzera "L" mushure megiredhi-yakadai se316L, 304L. Sei tichifanira kuderedza carbides? Kunyanya kudzivirira "intergranular corrosion". Intergranular corrosion, kunaya kwecarbides panguva yekupisa-kupisa kwesimbi, kunoparadza chisungo pakati pezviyo zvekristaro, zvichideredza zvakanyanya kusimba kwesimbi. Uye nzvimbo yesimbi kazhinji inenge ichiri yakasimba, asi haigoni kumira pakugogodza, saka inhara ine ngozi.
304Lsimbi isina ngura
Sesimbi yakaderera-kabhoni 304, kushorwa kwayo kwakafanana neiyo 304 simbi pasi pemamiriro akajairwa, asi mushure mekutambisa kana kuzorora kwekushushikana, kuramba kwayo kune intergranular corrosion kwakanakisa. Iyo inogona zvakare kuchengetedza yakanaka corrosion kuramba pasina kupisa kupisa uye inogona kushandiswa pa -196 ℃～800 ℃.
316Lsimbi isina ngura
Seyakaderera-kabhoni yakatevedzana ye316 simbi, mukuwedzera kune yakafanana maitiro se316 simbi, ine yakanaka intergranular corrosion resistance. Inogona kuiswa kune zvigadzirwa zvine zvakakwirira zvinodiwa zve-anti-intergranular corrosion, pamwe nemichina yekunze mumaindasitiri emakemikari, marasha, uye peturu, zvidyarwa zvemakemikari nemimwe minda. Kunyanya kukanganiswa kune intergranular corrosion hazvirevi kuti zvisiri-yakaderera kabhoni zvinhu zvinonyanya kubatwa nekuora. Munzvimbo yakakwirira-chlorine, kunzwa uku kwakakwirira zvakare. Iyo Mo yemukati ye316L inoita kuti simbi ive nekuramba kwakanaka kugomba gomba uye inogona kushandiswa zvakachengeteka munzvimbo dzine halogen ions dzakadai seCl-.
HENGKO Stainless simbi sefa chinhu chakagadzirwa ne316 uye 316L, ine mukana wekupisa tembiricha kuramba, yakanaka corrosion kuramba, kusimba kwepamusoro, uye yakasimba yekutarisa malink kuti ive nechokwadi chekuti mhando yezvigadzirwa kunze kwefekitori zvinopfuura tsika.
Heino kuenzanisa kwekusiyana kukuru muzvivakwa uye hunhu hweStainless simbi mhando 304, 304L, 316, uye 316L:

1. Kuumbwa: 316 uye 316L vane molybdenum yakawedzerwa iyo inowedzera kurwisana kwavo nekuora, kunyanya munzvimbo dzechloride.
2. Mechanical Properties: Iwo 'L' akasiyana (304L ne316L) kazhinji ane simba rakaderera zvishoma nekuda kwekuderedzwa kwawo kabhoni, asi anopa zvirinani weldability.
3. Corrosion Resistance: 316 uye 316L yakakwirira mukudzivisa kuora kana ichienzaniswa ne304 uye 304L, kunyanya munzvimbo dzegungwa uye dzakakwirira chloride.
4. Formability: Iwo 'L' akasiyana (304L ne316L) anopa kuumbwa kuri nani nekuda kwekuderedzwa kwawo kabhoni.
5. Weldability: Iyo yakaderedzwa kabhoni yemukati mu304L uye 316L inoderedza njodzi yekunaya kwecarbide panguva yewelding, ichiita kuti ive yakakodzera kune welded application pane avo vasiri L.
6. Zvikumbiro: Zvikumbiro zvakapiwa ingori mienzaniso mishomanana, uye imwe neimwe yemhando yesimbi isina tsvina inogona kushandiswa mune mamwe akawanda maapplication zvichienderana nezvinodiwa chaizvo.
Ongorora: Izvo chaizvo zvivakwa zvinogona kusiyana zvichienderana nemugadziri uye chaiwo mamiriro ekugadzirisa. Gara uchitarisa kune dhetabheti yemugadziri kana zviyero kuti uwane ruzivo rwakakwana.
Iyo Stainless simbi sefa element ine chaiyo mhepo pores, uye mafirita pores ari mayunifomu uye akaenzana akagoverwa; Yakanaka mhepo permeability, inokurumidza gasi-mvura yekuyerera mwero uye yakaenzana yakagovaniswa kusiyana. Kune akasiyana siyana saizi yakatarwa uye mhando dzemagadzirirwo ekusarudza kubva, uye anogona zvakare kugadzirwa zvinoenderana nezvinodiwa. Iyo simbi isina tsvina yakashongedzwa chikamu yakanyatsobatanidzwa neyakavharwa goko, iyo yakasimba uye isiri kudonha uye yakanaka; inogona zvakare kuvakwa yakananga mugoko rinopinda nemhepo ine chitarisiko chakazara mhepo uye pasina zvimwe zvakasimba zvishongedzo.
Wakavhiringika pamusoro pemisiyano pakati pesimbi isina tsvina 304, 304L, 316, uye 316L?
Usanetseke, timu yedu yenyanzvi kuHENGKO inogona kukubatsira kuti unzwisise misiyano uye uwane yakanakisa sarudzo yeprojekiti yako kana application.
Taura nesunhasi kuti utange uye kutora danho rekutanga pakuita sarudzo ine ruzivo.
