Vasega 3CR12 u'amea u'amea o se tau maualalo togi o chromium o lo'o i ai uamea stainless faia e ala i le suia o meatotino o le vasega 409 u'amea. E tetee malu corrosion ma susu wear.It na uluai atiina ae e Columbus Stainless Company i lalo o le faailoga tusi resitala "3CR12" .O isi igoa mo lenei vasega e aofia ai UNS S40977 / S41003 ma 1.41003.
O isi igoa e tutusa ma 3CR12 togi e aofia ai ASME SA240 togi, ASTM A240/A240M togi, ma EN 10088.2.Ae ui i lea, EN 10028.7 e aofia ai foi le vasega 1.4003, lea e aofia ai uamea stainless mo faamoemoega mamafa.
O vaega o loʻo mulimuli mai o le a tuʻuina atu mea taua o le vasega 3CR12 uʻamea uʻamea uʻamea, laupepa ma ipu e faʻatatau i le Euronorm S41003, S40977, ASTM A240 / A240M ma le EN 10088.2 1.4003.
O loʻo i luga e naʻo faʻatusatusaga faigata.O lenei laulau ua faʻamoemoe e tuʻuina atu se faʻatusatusaga o mea faʻapitoa faʻapitoa, ma o faʻamatalaga e le faʻaletulafono.E mafai ona faʻamaonia faʻamatalaga muamua pe a manaʻomia tutusa tutusa.
Vasega 3CR12 uamea u'amea e mafai ona faaaoga i talosaga e alumini, u'amea po o carbon uamea maua ai taunuuga leaga ona o lona tetee atu i acids malosi ma faavae, faapea foi le ta'e e mafua mai i le chloride stress corrosion.Ae ui i lea, e le pei o le Vasega 304, Vasega 3CR12 o loʻo i ai le teteʻe aupito maualalo i crevice ma pitting corrosion i luma o chlorides.
I lalo o tulaga ambient, o le vasega 3CR12 ua faaleleia le faapalepale i le vai ma chlorides, e pei o le corrosiveness o le chloride anotusi ua mitigated e nitrate ma sulfate ions.O se tasi o le itu le lelei autu o le vasega 3CR12 o le i luga o le mea ua teisi corroded pe a faʻaalia i soʻo se ituaiga o siosiomaga. E faʻatapulaʻa i lenei mea e faʻaaogaina ai mea teuteu.
3CR12 vasega uʻamea uʻamea faʻaalia fouling tetee i le va o 600 ma 750 ° C i luma o le ea ma i le va o 450 ma 600 ° C i totonu o se siosiomaga pressurized. O mea e avea brittle ma faaumiumi aafiaga vevela i le va o 450 ma 550 ° C. Ae peitai, o le mea e le aveesea lona aafiaga tetee i lenei tulaga vevela.
Vasega 3CR12 uamea u'amea ua annealed i le 700 i le 750 ° C, vaevaeina i 25mm vaega, vaega taitasi susu mo 1.5 itula. Ona tuu lea o le mea cool.Care e tatau ona ave e puipuia faamaaa i le taimi o le vevela treatment.O mea tau masini ma corrosion tetee o lenei vasega e aafia i le tineia togafitiga.
O auala uʻamea e faʻaaogaina mo austenitic stainless steels e mafai ona faʻaaogaina i le vasega 3CR12 stainless steels. Mafaufau i tekinolosi faʻaogaina maualalo vevela e pei o GMAW (MIG) ma GTAW (TIG). I le uelo, vasega 309 filler uaea muaʻi faʻamaonia i le AS 1554.6 e sili. e mafai ona aveese le lanu o le oloa soldered faaaoga kesi lagolago po o auala e pei o le faamamaina ma le pikiina.
O le masini o le 3CR12 grade stainless steel e tusa ma le 60% o le uʻamea vaivai. O la latou galuega faʻamalosi fua e maualalo ifo nai lo austenitic steels, o lea e leai se auala faʻapitoa e manaʻomia.
Vasega 3CR12 pepa uamea e maua i se tulaga masani Hot Rolled Annealed ma Pickled (HRAP) faaiu, ma coils o loo maua i le 2B po o le 2D faaiu e mafai foi ona gaosia mea uliuli mai mea vevela loʻo, ma tuua ai se mea uliuli oxidized i luga o le steel.3CR12 vasega maeʻa uliuli e lelei le corrosion teteʻe ma itiiti feeseeseaʻiga, o lea e talafeagai mo talosaga ofu eseese.
Taeao lelei Richard, ou te fiafia e tuʻuina atu ia te oe soʻo se aofaʻi o 3Cr12. Matou te tuʻuina atu mea i lalo o le Cromgard C12 brand. Faʻamolemole valaʻau mai ia te aʻu ile 719-597-2423.Jane Robinson.
O manatu o loʻo faʻaalia iinei o manatu ia o le tusitala ma e le o atagia mai ai manatu ma manatu o AZoM.com.
I Advanced Materials ia Iuni 2022, na talanoa ai AZoM ma Ben Melrose o International Syalons e uiga i le maketi o meafaitino maualuluga, Alamanuia 4.0, ma le tuleia i luga ole net zero.
I Advanced Materials, AZoM talanoa ma General Graphene's Vig Sherrill e uiga i le lumanaʻi o graphene ma pe faʻafefea ona faʻaititia e le latou tekonolosi gaosiga o tau e tatalaina ai se lalolagi fou o talosaga i le lumanaʻi.
I lenei faatalanoaga, AZoM talanoa ma Levicron Peresitene Dr. Ralf Dupont e uiga i le gafatia o le fou (U) ASD-H25 afi afi mo le semiconductor alamanuia.
Su'esu'e le OTT Parsivel², o se mita leisa e mafai ona fa'aoga e fua ai ituaiga uma o timuga. E mafai ai e tagata fa'aoga ona aoina fa'amatalaga i le tele ma le saoasaoa o vaega pa'u'u.
