I-QN1803 (304D) ipleyiti yensimbi engenasici
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, i-acetic acid + ityuwa kunye nezinye iimeko ezingcono kakhulu
304 intsimbi engenasici.
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 kwe 45%. Nxiba ukumelana kunye
ukudinwa ukusebenza ngcono kune 304 steel stainless.
I-5) ukusebenza kakuhle kwe-welding, amandla emva kwe-welding aphezulu kunaleyo ye-304 yentsimbi engenasici, kunye nokumelana nomhlwa
ithelekiseka naleyo ye-304 yentsimbi engatyiwayo.
