I-304L inguqulo ye-304 enekhabhoni ephansi. Isetshenziswa ezingxenyeni ze-heavy gauge ukuze kube nokushibilika okuthuthukisiwe.
I-304H, uhlobo olunekhabhoni ephezulu, iyatholakala futhi ukuze isetshenziswe emazingeni okushisa aphezulu.

Lokhu kuqhathanisa kulinganiselwa kuphela. Uhlu luhloselwe ukuqhathanisa izinto ezifanayo ngokusebenza hhayi njengohlelo lwezinto ezilingana nesivumelwano. Uma kudingeka izinto ezilingana ngqo, kufanele kubhekwe imininingwane yokuqala.
Amabanga Angase Ahluke
| Ibanga | Kungani kungase kukhethwe esikhundleni se-304 |
| 301L | Kudingeka izinga eliphezulu lokuqina komsebenzi kwezinye izingxenye ezakhiwe ngomqulu noma ezinwetshiwe. |
| 302HQ | Izinga eliphansi lokuqina komsebenzi liyadingeka ukuze kufakwe izikulufo, amabhawodi nama-rivets ngokubandayo. |
| 303 | Kudingeka imishini ephezulu, kanye nokumelana nokugqwala okuphansi, ukwakheka kanye nokushintshwa kuyamukeleka. |
| 316 | Kudingeka ukumelana okuphezulu kokugqwala kwemigodi kanye ne-crevice, ezindaweni ezine-chloride |
| 321 | Kudingeka ukumelana okungcono namazinga okushisa angaba ngu-600-900 °C… i-321 inamandla okushisa aphezulu. |

| 430 | Kudingeka izindleko eziphansi, futhi ukumelana nokugqwala okuncishisiwe kanye nezici zokwenziwa kuyamukeleka. |
I-Jiangsu Hangdong Metal Products Co., Ltd. iyinkampani engaphansi kwe-Jiangsu Hangdong Iron & Steel Group Co., LTD. Iyinkampani yocwaningo nentuthuko, ukukhiqiza, ukuthengisa, isevisi kwelinye lamabhizinisi ochwepheshe okukhiqiza izinto zensimbi. Imigqa yokukhiqiza eyi-10. Indlunkulu itholakala eDolobheni laseWuxi, eSifundazweni saseJiangsu ngokuhambisana nomqondo wentuthuko othi “ikhwalithi inqoba umhlaba, impumelelo yesevisi ikusasa”. Sizibophezele ekulawuleni ikhwalithi okuqinile kanye nensizakalo ecabangelayo. Ngemva kweminyaka engaphezu kweyishumi yokwakha nokuthuthukisa, sesibe yinkampani yobuchwepheshe yokukhiqiza izinto zensimbi ezihlanganisiwe. Uma udinga izinsizakalo ezihlobene, sicela uxhumane nathi:info8@zt-steel.cn
