Insimbi engagqwali 304,304L,304H

Insimbi engagqwali 304 kanye nensimbi engagqwali 304L yaziwa nangokuthi 1.4301 futhi 1.4307 ngokulandelana. I-304 iyinsimbi engagqwali eguquguquka kakhulu futhi esetshenziswa kabanzi. Kusakhulunywa ngezinye izikhathi ngegama layo elidala elithi 18/8 elisuselwe ekwakhiweni kwegama elithi 304 kube ngu-18% we-chromium kanye ne-nickel engu-8%. I-304 insimbi engagqwali iyibanga le-austenitic elingadonswa ngokujulile kakhulu. Lesi sakhiwo siholele ekutheni i-304 ibe yibanga eliphakeme elisetshenziswa ezinhlelweni ezinjengamasinki namapani.

I-304L inguqulo yekhabhoni ephansi engu-304. Isetshenziswa kuzingxenye zegeji esindayo ukuze kuthuthukiswe ukushisela.

304H, okuhlukile kokuqukethwe kwekhabhoni ephezulu, nakho kuyatholakala ukuze kusetshenziswe emazingeni okushisa aphezulu.

Amanye Amabanga Angenzeka

Ibanga	Kungani ingase ikhethwe esikhundleni sika-304
301L	Izinga eliphezulu lokuqina komsebenzi liyadingeka kuzingxenye ezithile ezakhiwe noma ezinwetshiwe ezakhiwe.
302HQ	Izinga eliphansi lokuqina lomsebenzi liyadingeka ekubunjweni okubandayo kwezikulufu, amabhawodi nama-rivets.
303	Imishini ephakeme edingekayo, futhi ukumelana nokugqwala okuphansi, ukwakheka nokushisela kuyamukeleka.
316	Ukumelana okuphezulu nokugqwala nokugqwala kuyadingeka, ezindaweni ezine-chloride
321	Ukumelana okungcono nokushisa okungaba ngu-600-900 °C kuyadingeka...321 inamandla okushisa aphezulu.
3CR12	Izindleko eziphansi ziyadingeka, futhi ukumelana nokugqwala okuncishisiwe nokushintsha kombala okuwumphumela kwamukelekile.
430	Izindleko eziphansi ziyadingeka, futhi ukumelana nokugqwala okuncishisiwe nezici zokwenziwa ziyamukeleka.
