Kazhinji, VJ Piping inogadzirwa nesimbi isina tsvina inosanganisira 304, 304L, 316 uye 316Letc. Pano tichazivisa muchidimbu maitiro emhando dzakasiyana-siyana dzesimbi isina tsvina.
SS304
304 pombi yesimbi isina tsvina inogadzirwa zvinoenderana neAmerican ASTM standard yemhando yesimbi isina tsvina.
304 simbi isina tsvina pombi yakaenzana neyedu 0Cr19Ni9 (OCr18Ni9) pombi yesimbi isina tsvina.
304 simbi isina tsvina chubhu sesimbi isina tsvina inonyanya kushandiswa mumidziyo yechikafu, zvakajairika makemikari michina, uye indasitiri yesimba reatomu.
304 Stainless simbi pombi ipombi yepasirese yesimbi isina tsvina, inoshandiswa zvakanyanya mukugadzira yakanaka yakazara kuita (corrosion resistance uye formability) midziyo uye zvikamu.
304 Stainless simbi pombi ndiyo inonyanya kushandiswa simbi isina tsvina, inopisa inodzivirira kupisa simbi. Inoshandiswa mumidziyo yekugadzira chikafu, general makemikari midziyo, simba renyukireya, nezvimwe.
304 Stainless simbi chubhu yemakemikari emhando C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
Stainless Steel 304 uye 304L Performance Difference
304L inonyanya kushingirira, 304L ine kabhoni shoma, 304 isimbi yepasi rose, uye inoshandiswa zvakanyanya mukugadzirwa kwemidziyo uye zvikamu zvinoda kuita kwakanaka kwakazara (kupokana nekusagadzikana). 304L inosiyana ye304 Stainless simbi ine yakaderera kabhoni yemukati uye inoshandiswa kune welding application. Iyo yakaderera kabhoni yemukati inoderedza kunaya kwecarbides munzvimbo inobatwa nekupisa pedyo neweld, izvo zvinogona kutungamirira kune intergranular corrosion (welding erosion) musimbi isina tsvina mune dzimwe nharaunda.
304 inoshandiswa zvakanyanya, ine yakanaka corrosion resistance, kupisa kupisa, kuderera kwekushisa kwesimba uye michina yemagetsi; Yakanaka yekupisa yekupisa, senge kutsika nekukotama, pasina kupisa kurapwa kuomesa chiitiko (hapana magineti, uchishandisa tembiricha -196 ℃-800 ℃).
304L ine yakanakisa kupikisa gorosi muganho ngura mushure mekudzikisira kana kushushikana kwekunetseka: inogona kuchengetedza yakanaka kuonda kunyangwe pasina kupisa kupisa, kushanda tembiricha -196 ℃-800 ℃.
SS316
316 simbi isina tsvina zvakare ine yakanaka chloride erosion properties, saka inowanzoshandiswa munzvimbo dzeMarine.
Corrosion inodzivirira Stainless simbi chubhu fekitori
Corrosion resistance iri nani pane 304 simbi isina tsvina, mukugadzira pulp uye bepa rine yakanaka corrosion resistance.
Uye 316 simbi isina tsvina zvakare inopokana neMarine uye ane hukasha maindasitiri mamiriro. Kupisa kupikisa mu 1600 madhigirii pasi pekushandiswa kusingapfuuri uye mu 1700 madhigirii pasi pekushandiswa kunoramba kuripo, 316 simbi isina tsvina ine yakanaka oxidation resistance.
Muchikamu che800-1575 madhigirii, zviri nani kuti usarambe uchishandisa 316 simbi isina tsvina, asi muhutano hwekushisa kunze kwekushandiswa kunoramba kuripo kwe316 simbi isina tsvina, simbi isina tsvina ine kunaka kwekupisa.
Iyo carbide precipitation resistance ye316 Stainless simbi iri nani pane iya ye316 Stainless simbi uye inogona kushandiswa mutembiricha iri pamusoro.
316 simbi isina tsvina ine yakanaka welding performance. Inogona kugadzirwa uchishandisa ese akajairwa welding nzira. Welding inogona kushandiswa zvinoenderana nekushandiswa kwe316Cb, 316L kana 309CB Stainless steel filler tsvimbo kana electrode welding. Kuti uwane iyo yakanakisa corrosion resistance, iyo welded chikamu che316 Stainless simbi ichave yakanyungudutswa mushure mekugadzira. Post weld annealing haidiwe kana 316L simbi isina tsvina ikashandiswa.
Mashandisirwo akajairika: mapira uye midziyo yebepa zvinopisa kupisa, michina yekudhaya, michina yekugadzira firimu, mapaipi, uye zvinhu zvekunze kwezvivakwa zvemudhorobha munzvimbo dzemahombekombe.
Antibacterial Stainless Steel
Nekusimukira kwehupfumi, simbi isina tsvina muindasitiri yezvekudya, masevhisi ekubika uye mashandisirwo ehupenyu hwemhuri ari kuwedzera uye zvakanyanya, zvinotarisirwa kuti kunze kwesimbi isina tsvina yemumba midziyo uye tableware, inopenya uye yakachena sechinhu chitsva, asi zvakare ine. the best mildew, antibacterial, the sterilization function.
Sezvatinoziva tese, mamwe simbi, senge sirivheri, mhangura, bismuth uye zvichingodaro zvine antibacterial, bactericidal effect, inonzi antibacterial stainless simbi, iri musimbi isina tsvina kuwedzera huwandu hwakakodzera hwezvinhu zvine antibacterial effect (yakadai semhangura. , sirivheri), kugadzirwa kwesimbi mushure mekurapa kwekupisa kweantibacterial, nekugadzikana kwekugadzirisa kushanda uye kushanda kwakanaka kweantibacterial.
Mhangura ndiyo chinhu chakakosha cheantibacterial, yakawanda sei yekuwedzera haifanirwe kungofunga antibacterial pfuma, asi zvakare inovimbisa yakanaka uye yakagadzikana kugadzirisa zvinhu zvesimbi. Iyo yakakwana yakawanda yemhangura inosiyana nemhando dzesimbi. Kemikari inogadzirwa neantibacterial stainless steel yakagadzirwa neJapan Nissin Steel inoratidzwa muTebhu 10. 1.5% mhangura inowedzerwa kune ferritic simbi, 3% kune martensitic simbi uye 3.8% kune austenitic simbi.
