Imigoqo engenasici emnyama yenziwa ngenqubo yokwakha. Lapha, le nsimbi idlula ngokusebenzisa ama-rolls ambalwa nezinto eziluhlaza ezinjengezikweletu nama-blooms zifudunyezwa cishe cishe ama-degrees angama-1200. Idlula izinga lokushisa lensimbi kabusha.

Njengomhlinzeki wensimbi engagqwali yensimbi, HT PIPE unikeza imikhiqizo yebha kanye nezinsizakalo. Insimbi engenasici akuyona into eyodwa, kepha igama lomndeni wamatshe alwa nokugqwala. Njengokutholwa okuningi kwesayensi, umsuka wensimbi engenasici waba yingozi. Ngo-1913, uSheffield, eNgilandi, uHarry Brearley ubesebenza ekuthuthukisweni kwe-alloy yensimbi entsha yemiphongolo yesibhamu. Wabona ukuthi amanye amasampula akhe awagqwala futhi kwakunzima ukukwenza. Lama-alloys aqukethe cishe i-chromium engu-13%. Ukusetshenziswa kokuqala kwalezi zinsimbi ku-cutlery, lapho uShiffield kamuva waba odumile. Umsebenzi ofanayo eFrance uholele ekuthuthukisweni kwama-autenitic steren stering.

Enye inzuzo yeBanga 304 Ibha yensimbi engenasici ngaphezulu kweBanga 303 ukuthi nzima kancane futhi inokuphikiswa okungcono kokugqwala. Ngenxa yalokhu, ibha yensimbi engu-304 yensimbi engenasici isetshenziswa ngamanani amakhulu ekwakheni ama-fasteners nokulungiswa njengamantongomane, ama-bolts, ama-washer, iziqeshana, ukugcwala. Imikhiqizo eyenziwe nge-grade 304 insimbi engagqwali embonini ye-fastener imvamisa ibizwa ngokuthi "A2".

Ibanga le-304 liyindlela eguquguqukayo, ethandwayo futhi enomnotho yezicelo eziningi. Kodwa-ke, ukusho lokho, ukusetshenziswa kanye nokusebenzisa izinduku zensimbi ezingama-316 zihluke kakhulu ezintanjeni zensimbi ezingama-304. Okokuqala, i-ASTM A276 Thayimba Round 316 Round Bar ilungele ukusetshenziswa ezindaweni zasemanzini njengoba imelana namanzi olwandle kanye namanzi anosawoti kanye nezixazululo ezihlukile ku-grade 304 ngeke zibole ezindaweni zasolwandle.

Ifana nebanga le-304, i-304L SS Hex Bar isetshenziselwa izinhlelo zokusebenza ezidinga ukulawulwa kwentengo. I-Impelsex ephelele ingenye yabahlinzeki bemigoqo yokusika-kubude kuwo wonke amabanga, ukukongela izindleko ezingezekile. Singumhlinzeki wensimbi engagqwali engama-304l, ukuhlinzeka ngemigoqo yensimbi kuyo yonke imikhawulo.

Izicelo zezinduku zensimbi ezingenasici Izakhiwo zayo ukuthi lokhu kubhekwa njenge- "free ukucubungula okuhlukile" kuka-410, ngokumelana okusebenzayo kokugqwala kuma-acid okudla kwemvelo, usawoti we-alkaline, amanzi kanye nama-atmorshere amaningi.

Njengoba izinduku zensimbi ezingenasici ziza ngobumo obuningi nobukhulu obufana neflethi, hexagonal noma i-hexagonal, nxazonke kanye nesikwele. Kakhulu, uhlobo lwe-bar luchaza ukusetshenziswa kwalo endaweni yesicelo noma emandleni.
Imigoqo yensimbi engagqwali yenziwa ngenqubo yokwakha. Lapha, le nsimbi idlula ngokusebenzisa ama-rolls ambalwa nezinto eziluhlaza ezinjengezikweletu nama-blooms zifudunyezwa cishe cishe ama-degrees angama-1200. Idlula izinga lokushisa lensimbi kabusha.

Izinzuzo zokusebenzisa insimbi engenasici 304 \ 303l imigoqo eyindilinga ifaka okuqukethwe okuphansi kwekhabhoni, okususa ukuhanjiswa kwekhabhoni ngesikhathi se-welding. Insimbi engenasici 304l imigoqo eyindilinga engu-304l ine-tensile evulekile yamandla futhi inezakhiwo zokushisa eziphansi eziphendula kahle ekuqiniseni amandla okusebenza.

Zonke izinsimbi ezingenasici zingama-alloys asuselwa kwinsimbi aqukethe okungenani cishe nge-10.5% chromium. I-chromium ku-alloy yakha isendlalelo sokuzivikela esibonakalayo soxide. Le nhlangano ye-oxide yenza ukumelana nokuqina kwensimbi engagqwali. Imvelo yokuzipholisa ye-oxide ungqimba isho ukuthi ukumelana nokukhulisa kuhlala kufana noma ngabe kuyindlela yokukhiqiza. Noma ingaphezulu kokuqukethwe kunqunywa noma kulimele, kuzophola futhi kuhlale kungamelana nokugqwala. Ngakolunye uhlangothi, i-Plain Carbon Steel ingavikeleka ekugcekeni ngokupenda noma ezinye izigqoko ezifana ne-galvaning.
