I-Q355NH yentsimbi yemozulu enezinto ezisetyenziswayo ze-welding

Intshayelelo kwintsimbi yemozulu

Intsimbi yemozulu linqanaba lentsimbi elinokumelana nokugqwesa emoyeni, oko kukuthi ukongeza inani elincinci le-Cr, i-Ni, i-Cu, i-P kunye nezinye izinto kwintsimbi ye-carbon ukwenza umaleko okhuselayo kumphezulu we-matrix yesinyithi, ngaloo ndlela ucotha ngakumbi. umhlwa. Ukumelana nomhlwa kwi-atmospheric yentsimbi yemozulu ngama-2 ~ 8 amaxesha entsimbi eqhelekileyo yekhabhoni, enokumelana nomhlwa, ukwandisa ubomi benkonzo yamacandelo esakhiwo, ukunciphisa kunye nokunciphisa ukusetyenziswa, njl., ikakhulu ezisetyenziswa kwizithuthi, iibhulorho, izitya, izakhiwo, iinqaba. kunye nokunye ukuvezwa kwexesha elide kwizakhiwo zentsimbi ye-atmospheric.

Q355NH ukusebenza kwentsimbi yemozulu

I-Q355NH yeyentsimbi edityanisiweyo yemozulu

Isalathiso sokuxhathisa ukonakala kwe-atmospheric

Isalathiso sokumelana ne-atmospheric corrosion (I) sisalathiso esibalulekileyo sokuvavanya ukuxhathisa kwemozulu yezinto eziphathekayo, ubukhulu besalathiso, ngcono ukuxhathisa kwi-atmospheric corrosion yentsimbi, kukholelwa ngokubanzi ukuba xa isalathisi (I) ≥ 6.0 intsimbi inomoya ongcono we-atmospheric. ukumelana nomhlwa.

Isalathiso sokuxhathisa ukuthotywa kwe-atmospheric (I) sibalwa ngolu hlobo lulandelayo:
I=26.01(%Cu)+3.88(%Ni)+1.20(%Cr)+1.49(%Si)+17.28(%P)-7.29(%Cu)(%Ni)-9.10(%Ni)(%P) )-33.39(%Cu)2

Njengesiqhelo, siqhubeka sikubonelela ngezinto ezityiwayo ezikumgangatho ophezulu kunye neenkonzo!
