SPA-H weathering icandelo intsimbi, ipleyiti Steel Corden
1. Inkcazo elula:
I-SPA-Hintsimbi yemozulu, ekwaziwa njengentsimbi enganyangekiyo kwi-atmospheric, ibhekisa kuhlobo lwe-low-.ingxubevangeintsimbi ephezulu
iqulethe ixabiso elincinci lezinto ezixutywayo, ixabiso eliphantsi, kunye nokumelana nokubola okuhle kwi-atmosfera. Eyona alloying
izinto ezi Cu, P, Cr, Ni, Si, Mn, V, RE, njl. Ngexesha lokusetyenziswa kwentsimbi yemozulu, ifilimu ekhuselweyo exineneyo kwaye iqhotyoshelwe ngokuqinileyo.
iimveliso ze-corrosion ziya kubumba ngokuthe ngcembe kumphezulu ukuthintela ioksijini, amanzi kunye nezinye imidiya ezonakalisayo emoyeni
ngakumbi ukugqwesa i-substrate, ukuze izinga lokubola lincitshiswe kakhulu xa kuthelekiswa nentsimbi ye-carbon. . Ngenxa yamandla ayo aphezulu kunye
ixabiso elifanelekileyo, ixabiso lemveliso liphantsi kakhulu kunensimbi engenasici. Umgangatho wesigqeba se-SPA-H ngu: JISG3125-2015.
2. Ukuqulunqwa kwemichiza:

3. IiPropati zoomatshini
| IBanga | IPropati yoomatshini | ||
| Amandla eSivuno (N/mm2)/(Mpa) | Amandla Okuqina (N/mm2)/(Mpa) | Ubude (%) | |
| I-SPA-H | 355 | 490 | ≥22 |
| Q235NH | ≥235 | 360-510 | ≥23 |
| Q355NH | 355 | 490-630 | ≥20 |
| Q450NQR1 | 345 | 470-630 | ≥21 |
4. Isicelo:
I-1) I-SPA-H yintsimbi yemozulu yokulungisa isitya, ukusika kunye ne-welding. I-SPA-H isetyenziswa ikakhulu kwizikhongozeli zeenqanawa,
iibhulorho zentsimbi, iinqanawa kunye neetanki zokuthintela ukubola kwe-atmospheric.
I-2) I-SPA-H yentsimbi yemozulu isetyenziselwa ikakhulu ukwenza izitya. Ushishino lwezothutho lweekhonteyina lunembali engaphezulu
Iminyaka engama-50 emhlabeni. Kwiminyaka engama-30 eyadlulayo, inqwelomoya yelizwe lam yayingasenanto. Ukusukela kuhlaziyo kunye nokuvula, ilizwe lam
ukwakhiwa kwezibuko kunye nokuthuthwa kweekhonteyina kuqhubekile ukuphuhlisa. Ingakumbi kwiminyaka yakutshanje, uluntu lwamazwe ngamazwe luye lwajamelana
imeko “yesikhongozeli esinye kunzima ukuyifumana.
5. Umgaqo wokuxhathisa ukonakala:
Xa intsimbi ibonakaliswe kukukhanya kwelanga kunye nomoya, ukuxhathisa ukubola kwayo kubaluleke kakhulu. Emva kokongeza i-phosphorus, ubhedu, i-chromium,
i-nickel kunye nezinye izinto ezilandelwayo kwintsimbi, ifilimu ekhuselweyo kunye neyomeleleyo iya kwenziwa phezu kwezinto zobhedu, ezinokuthi zenziwe.
inokudlala indima ethile yokukhusela.
