Iintsimbi ezisetyenziswa rhoqo ezingenasici yi-304 kunye ne-316, kunye nezandiso eziquka i-304L, i-316L, kunye ne-316H. Ukongeza, kukho i-440C, i-2507, njl. Ngoko ke zithini i-CF8M kunye ne-CF3? Ndingayibona njani i-F316? Kwenzeka ntoni nge-TP316L?
1. Ukuze sicacise oku, masiqale sijonge uhlobo lwezinto ezisetyenziswayo. Kwishishini leevalvu nezixhobo, izinto ezisetyenziswayo ikakhulu zii-forgings, i-bar stock, i-castings, kunye neepayipi. Zithini imigangatho ehambelanayo kwezi ntlobo zine zezinto ezisetyenziswayo kushishino lwethu? Nceda ujonge le theyibhile:
|
| 304 | 304L | 316 | 316L |
| Ukubumba | F304 | F304L | F316 | F316L |
| Ivenkile yeBhari | 304 | 304L | 316 | 316L |
| Ukuphosa | CF8 | CF3 | CF8M | CF3M |
| Umbhobho | TP304 | TP304L | TP316 | TP316L |
Izinto zebar stock zamkela umgangatho osisiseko, kwaye u-F wongezwa kwi-forging, apho u-F emele i-forging; u-C wongezwe kwi-casting, apho u-C emele i-casting; u-TP wongezwe kwi-pipe, oko kuthetha i-pipe.
2, Yintoni umahluko phakathi kwe-304 kunye ne-316? Imele ntoni i-L ye-304L kunye ne-316L? Ithetha ukuthini i-H ye-316H? Makhe sijonge itheyibhile yokwakheka kweekhemikhali zamanqanaba ahlukeneyo e-ASTM A276, apho i-316H ikumgangatho we-ASTM A182 (eli banga alifakwanga kumgangatho we-276):

Ngokwetheyibhile, kuyacaca ukuba u-L uthetha umxholo wekhabhoni ophantsi, u-H uthetha umxholo wekhabhoni ophezulu, kwaye umahluko phakathi kwe-316 kunye ne-304 kukongezwa kwento ye-Mo, oko kuthetha ukuba i-CF3M inento eyongezelelweyo ye-Mo xa ithelekiswa ne-CF3.
3、 Ngaphandle kwezi ntsimbi ziqhelekileyo ze-stainless steels ezi-3-series, zithini ezinye ii-2507, 440C nezinye? Ezi ntsimbi ziqhelekileyo ze-stainless steels ezineentloko ezi-3 zibizwa ngokuba zii-austenitic stainless steels, ngelixa i-2507 iyintsimbi ye-duplex (i-ferritic kunye ne-austenitic), i-440C yeyentsimbi ye-martensitic stainless steel, kwaye kukwakho neentsimbi ze-ferritic stainless steels ezifana ne-430.
Kuyabonakala ukuba ukuze kucaciswe ezi ntsimbi ziqhelekileyo ezingenasici, eyokuqala kukwahlula imo: iibhari zebha, njl.njl., eyesibini yimigangatho elandelwayo, kwaye eyesithathu ngumahluko ekubunjweni. Ukusuka kule mbono, emva kokuziqhelanisa nentsingiselo yeekhowudi zoonobumba, akunzima ukuqonda intsingiselo yala manqanaba.
