Umzi-mveliso othengisa kakhulu i-430 yePlayiti yeNsimbi eNgatyiwayo-QN1803 (304D) ipleyiti yentsimbi engenakutyiwa-Huaxin

1.  Inkcazelo:

Ibakala elitsha lemveliso ye-QN1803 lihlabathi lokuqala le-nitrogen ephezulu, ukumelana nokugqwala okuphezulu, i-nickel-saving austenitic steel stainless product.

Kwisiseko sokuqinisekisa ukuxhathisa ukubola okulingana ne-304 yensimbi engenasici, amandla ezinto eziphathekayo aphuculwe, kunye nezinto eziphathekayo.

iindleko ziyancitshiswa, okwenza kube yindleko ngakumbi kwaye kukhuphisane ngakumbi kwimarike kune-304 yensimbi engenasici.

Iimpawu zoyilo lwemveliso entsha: i-nitrogen ephezulu (≥2000ppm), i-chromium ephezulu (≥18%), i-nickel ephakathi (~ 3.0%) kunye nobhedu oluphezulu (≥1.5%).

Ngokusebenzisa iqonga ledijithali le-R&D ye-Thermo-Calc yesigaba se-thermodynamic sedayagram yesoftware kunye nohlalutyo lovavanyo lwedatha, ukulungelelanisa

Izinto ezixutywayo zecandelo ngalinye lesigaba aziphuculi kuphela ukuxhathisa ukubola kwemveliso, kodwa kwakhona kwenza amandla esivuno se-QN1803.

ngaphezulu kwe-1.3 ngokuphindwe ka-304.

I-QN1803 inezi mpawu zilandelayo:

1) i-corrosion corrosion ye-pitting equivalent PREN=Cr+3.3Mo+30N-Mn ingaphezulu kwe-19.0, ene-pitting resistance corrosion resistance as 304.

yenziwe ngentsimbi eshayinayo.

2) Ukumelana nomhlwa okufanayo kwi-dilute hydrochloric acid, dilute sulfuric acid, iacetic acid + ityuwa kunye nezinye iimeko ezingcono kakhulu

304 intsimbi engatyiwayo.

I-3) ukuxhathisa umhlwa kungcono kune-304 kwimeko yokusetyenziswa yokwenyani emva kokugoba, isitampu, isimo esinzima kunye nokunye okubandayo.

4) amandla isivuno ngaphezu 1.3 amaxesha ukuba 304 steel stainless, kwaye inobude obungekho ngaphantsi kwama-45%. Nxiba ukumelana kunye

ukusebenza kokudinwa kubhetele kune-304 yensimbi engenasici.

I-5) ukusebenza kakuhle kwe-welding, amandla emva kwe-welding aphezulu kunaleyo ye-304 yensimbi engenasici, kunye nokumelana nomhlwa

ithelekiseka naleyo ye-304 yentsimbi engatyiwayo.

2. Ukuthelekisa nezinto ezingama-304:

3. Uthelekiso lweePropati:
