Izinsimbi ezingagqwali ezisetshenziswa kakhulu yi-304 kanye ne-316, kanye nezandiso ezifaka phakathi i-304L, i-316L, kanye ne-316H. Ngaphezu kwalokho, kune-440C, i-2507, njll. Ngakho-ke iyini i-CF8M kanye ne-CF3? Ngingayibona kanjani i-F316? Kwenzekani nge-TP316L?
1、 Ukuze sicacise lokhu, ake siqale sibheke uhlobo lwezinto zokwakha. Embonini yama-valve nezinsimbi, izinto ezisetshenziswayo ikakhulukazi yizinto zokwakha, isitokwe sebha, ukuthunga, namapayipi. Yiziphi izindinganiso ezihambisanayo zalezi zinhlobo ezine zezinto zokwakha embonini yethu? Sicela ubheke leli thebula:
|
| 304 | 304L | 316 | 316L |
| Ukwakha | F304 | F304L | F316 | F316L |
| Isitoko Sebha | 304 | 304L | 316 | 316L |
| Ukulingisa | CF8 | CF3 | CF8M | CF3M |
| Ipayipi | I-TP304 | I-TP304L | I-TP316 | TP316L |
Izinto ezisetshenziswayo zebha zithatha ibanga eliyisisekelo, kanti u-F uyangezwa ekubumbeni, lapho u-F emele ukubumba; u-C ungeziwe ekubumbeni, lapho u-C emele ukubumba; u-TP ungeziwe epayipini, okusho ipayipi.
2、 Uyini umehluko phakathi kuka-304 no-316? Limelelani i-L ye-304L ne-316L? Lisho ukuthini i-H ye-316H? Ake sibheke ithebula lokwakheka kwamakhemikhali lamazinga ahlukene e-ASTM A276, lapho i-316H iyindinganiso ye-ASTM A182 (leli banga alifakiwe ku-276 standard):
| Ibanga | Ukwakheka Kwamakhemikhali，% | ||||||||

| C | Mn | P | S | Si | Cr | Ni | Mo | Okunye |
| 304 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 8.0-11.0 | … | … |
| 304L | 0.030 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 8.0-12.0 | … | … |
| 316 | 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 10.0-14.0 | 2.00-3.00 | … |
| 316L | 0.030 | 2.00 | 0.045 | 0.030 | 1.00 | 18.0-20.0 | 10.0-14.0 | 2.00-3.00 | … |
| 316H | 0.04-0.10 | 2.00 | 0.045 | 0.030 | 1.00 | 16.0-18.0 | 10.0-14.0 | 2.00-3.00 | … |
Ngokusho kwethebula, kusobala ukuthi u-L usho okuqukethwe kwekhabhoni ephansi, u-H usho okuqukethwe kwekhabhoni ephezulu, kanti umehluko phakathi kuka-316 no-304 ukwengezwa kwesakhi se-Mo, okusho ukuthi i-CF3M inesakhi se-Mo esengeziwe uma kuqhathaniswa ne-CF3.
3、 Ngaphandle kwalezi zinsimbi ezivamile zensimbi ezingenasici ezinochungechunge olu-3, yiziphi ezinye izinsimbi zensimbi ezingenasici ezingama-2507, 440C nezinye? Lezi zinsimbi ezivamile zensimbi ezingenasici ezinamakhanda amathathu zibizwa ngokuthi izinsimbi ezingenasici ezingama-austenitic, kuyilapho i-2507 iyinsimbi ephindwe kabili (i-ferritic ne-austenitic), i-440C ingeyensimbi engagqwali ye-martensitic, futhi kukhona nezinsimbi zensimbi ezingenasici ezifana ne-430.
Kungabonakala ukuthi ukuze kucaciswe lezi zinsimbi ezivamile ezingagqwali, okokuqala ukuhlukanisa isimo: amapayipi esitokwe sebha, njll., okwesibili amazinga alandelwayo, kanti okwesithathu umehluko ekubunjweni. Kusukela kulo mbono, ngemva kokujwayelana nencazelo yamakhodi ezinhlamvu, akunzima ukuqonda incazelo yalezi zigaba.
