Amabanga asisiseko ensimbi engenasici

Eqhelekileyo yenziwe ngentsimbi eshayinayoiimodeli
Iimodeli zentsimbi ezixhaphakileyo ezisetyenziswa ngokuqhelekileyo kwiisimboli zamanani, kukho uchungechunge lwama-200, uchungechunge lwama-300, uchungechunge lwama-400, luyi-United States of America yokumelwa, njenge-201, i-202, i-302, i-303, i-304, i-316, i-410, i-420, i-420, i-430 iisimboli zentsimbi ezisetyenziswayo, iisimboli zentsimbi, njl. njenge-1Cr18Ni9, 0Cr18Ni9, 0Cr17, 3Cr13, 1Cr17Mn6Ni5N, njl. njl., kwaye amanani abonisa umxholo wento ehambelanayo. 00Cr18Ni9, 1Cr17, 3Cr13, 1Cr17Mn6Ni5N njalo njalo, inombolo ibonisa umxholo wento ehambelanayo.

200 series: chromium-nickel-manganese austenitic steel stainless
300 series: chromium-nickel austenitic steel stainless
301: I-ductility elungileyo, isetyenziselwa iimveliso ezibunjiweyo. Inokwenziwa lukhuni ngesantya somatshini. Weldability elungileyo. Ukunxiba ukuxhathisa kunye namandla okudinwa kungcono kune-304 yensimbi engenasici.
I-302: ukuxhathisa i-corrosion kunye ne-304, ngenxa yomxholo wekhabhoni ephezulu kwaye ngoko ke amandla angcono.
I-302B: luhlobo lwentsimbi engatyiwayo enomxholo ophezulu wesilicon, enokumelana okuphezulu ne-oxidation yobushushu obuphezulu.
I-303: Ngokudibanisa isixa esincinci sesulfure kunye ne-phosphorus ukuze isebenze ngakumbi.
I-303Se: Ikwasetyenziselwa ukwenza iinxalenye zomatshini ezifuna isihloko esishushu, kuba le nsimbi engenasici inokusebenza kakuhle okushushu phantsi kwezi meko.
304: 18/8 intsimbi engenasici. Ibakala le-GB 0Cr18Ni9. 309: ukumelana nobushushu obungcono kune-304.
I-304L: Ukwahluka kwe-304 yensimbi engenasici kunye nomxholo wekhabhoni ephantsi, esetyenziswa apho i-welding ifunwa khona. Umxholo ophantsi wekhabhoni unciphisa imvula ye-carbides kwindawo echaphazelekayo ukushisa kufuphi ne-weld, enokuthi iholele kwi-intergranular corrosion (i-weld erosion) yensimbi engenasici kwezinye iindawo.
I-304N: Insimbi engenasici equkethe i-nitrogen, eyongezwa ukwandisa amandla entsimbi.
I-305 kunye ne-384: Equkethe amanqanaba aphezulu e-nickel, anomlinganiselo ophantsi wobunzima bomsebenzi kwaye afanelekile kuluhlu olubanzi lwezicelo ezifuna ukubanda okuphezulu.
308: Isetyenziselwa ukwenza iintonga ze-welding.
I-309, 310, 314 kunye ne-330: umxholo we-nickel kunye ne-chromium uphezulu kakhulu, ukwenzela ukuba kuphuculwe ukuxhathisa kwe-oxidation yentsimbi kumaqondo aphezulu kunye namandla okuhamba. Ngelixa i-30S5 kunye ne-310S zizinto ezihlukeneyo ze-309 kunye ne-310 yensimbi engenasici, umahluko kukuba umxholo wekhabhoni usezantsi, ukuze i-carbides ephantsi kufuphi ne-weld iyancipha. I-330 yensimbi engenasici inokumelana okuphezulu ngokukodwa kwi-carburization kunye nokuchasana nokutshatyalaliswa kobushushu.
I-316 kunye ne-317: iqulethe i-aluminium, kwaye ngoko ibe nokuchasana okungcono kakhulu kwi-corrosion ye-pitting kwi-marine and chemical industry environments kune-304 steel stainless. Phakathi kwabo, chwetheza 316 intsimbi engatyiwayongokwahlukahlukana kubandakanya i-316L ye-carbon low-carbon steel stainless steel, i-nitrogen-equkethe i-316N ephezulu yensimbi engenasici, kunye nomxholo ophezulu wesulfure we-free-machining steel stainless 316F.
I-321, i-347 kunye ne-348: i-titanium, i-niobium kunye ne-tantalum, i-niobium i-stabilized stabilized steel stabilized, ifanelekile ukusetyenziswa kumaqondo okushisa aphezulu kumacandelo adibeneyo. I-348 luhlobo lwentsimbi engatyiwayo efanelekileyo kushishino lwamandla enyukliya, i-tantalum kunye nobungakanani bokomba obudityaniswe nomgangatho othile wothintelo.
400 series: ferritic kunye martensitic steel stainless
I-408: Ukumelana nobushushu obuhle, ukuxhathisa ubuthathaka, i-11% Cr, i-8% ye-Ni.
I-409: olona hlobo lungabizi kakhulu (iBhrithani neMelika), edla ngokusetyenziswa njengemibhobho yokukhupha imoto, yintsimbi ye-ferritic (intsimbi yechromium)
I-410: i-martensitic (intsimbi ye-chromium ephezulu), ukumelana nokunxiba kakuhle, ukuxhathisa ukubola. I-416: isulfure eyongeziweyo iphucula ubuchule bezinto eziphathekayo.
I-420: "Isixhobo sokusika ibakala" intsimbi ye-martensitic, efana ne-Brinell high-chromium steel, intsimbi yokuqala engenasici. Ikwasetyenziselwa iimela zotyando kwaye inokwenziwa iqaqambe kakhulu.
430: Ferritic steel stainless, zokuhombisa, umz izincedisi imoto. Ukubunjwa okuhle, kodwa ukumelana nobushushu kunye nokumelana nokubola kuphantsi.
I-440: i-high-high-high-cut cut edge steel, i-carbon content content, emva kokuba unyango olufanelekileyo lokushisa lunokufumana amandla aphezulu esivuno, ubunzima bunokufikelela kwi-58HRC, yeyona nto inzima kakhulu insimbi engenasici. Owona mzekelo uxhaphakileyo wokusetyenziswa yi "razor blades". Kukho iintlobo ezintathu ezisetyenziswa ngokuqhelekileyo: 440A, 440B, 440C, kunye ne-440F (uhlobo olulula kumatshini).
500 Series: Ubushushu-resistant chromium ingxubevange intsimbi
600 Series: Martensitic precipitation-ukuqina intsimbi stainless
630: Eyona isetyenziswa ngokuqhelekileyo imvula-ukuqina uhlobo lwentsimbi stainless, edla ngokuba yi-17-4; 17% Cr, 4% Ni.
