Eqhelekileyo yenziwe ngentsimbi eshayinayoiimodeli
Iimodeli zentsimbi ezixhaphakileyo ezisetyenziswa ngokuqhelekileyo iisimboli zamanani, kukho 200 series, 300 series, 400 series, they are the United States of America’s representation, ezifana 201, 202, 302, 303, 304, 316, 410, 420, 430, njl., iimodeli zensimbi ezingenasici zaseChina zisetyenziswa kwiisimboli ze-elementi kunye namanani, njenge-1Cr18Ni9, 0Cr18Ni9, 0Cr17, 3Cr13, 1Cr17Mn6Ni5N, 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. Ukuwelda okulungileyo. 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 ngokukodwa okuphezulu 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), ukuxhathisa okulungileyo, 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 nomhlwa 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 alloy steel
600 Series: Martensitic precipitation-ukuqina intsimbi stainless
I-630: I-precipitation-hardening steel stainless steel ixhaphake kakhulu, ebizwa ngokuba yi-17-4; 17% Cr, 4% Ni.
