09cuppire {- b steel phaj yog ib qho hluav taws xob sib xyaw ua ke (Cu 0.20), chromium (thiab npib tsawg dua lossis sib npaug nrog 0.30%).
Los ntawm kev sib ntxiv ntawm phosphorus (P 0.07-0.15%), cov khoom siv hlau no tsuas yog siv cov khoom siv xeb thiab cov tshuaj tuab tiv thaiv kev ua kom zoo nkauj, sib txuas nrog kev thov kom zoo nkauj.
Nws cov txiaj ntsig lub zog yog tsis muaj tsawg tshaj li 345 MPa, tensile lub zog zoo li ntawm 470-630 MPa, thiab elongation feem ntau tsis pub tsawg tshaj 20%.
Piv rau cov pa roj carbon hlau, 09cuppe - b muaj 2-8 zaug dolospheric corrospherity dolospherity los ntawm 15-30 xyoos hauv cov acidic flue gas ib puag ncig.
09cuppe {{- b hlau daim hlau tau dav siv nyob rau hauv tsheb tsim khoom, cov choj tsheb, cov nkoj cia siab, nrog rau cov pa taws thiab boiler plhaub thiab boiler zoo li.
Lawv tsim nyog tshwj xeeb rau cov phiaj xwm xav tau ntev - tsis kam kam rau cov roj flue corrosion thaum tswj kev tsim qauv zoo nkauj.

Daim ntawv thov
Tuam Tshoj TB / T 1979 Txuj Ci 09Cupire - b huab cua ua kom zoo dua lossis sib npaug ntawm 470 MPa mpa, thiab elongation ntau dua lossis sib npaug rau 20%. Nws cov kev pabcuam lub neej nyob rau ib puag ncig ib puag ncig yog 2-8 zaug ntev dua li cov pa roj carbon hlau. Thawj cov ntawv thov muaj xws li:
Tsheb Raug{{0-} Feem ntau siv nyob rau hauv cov tsheb thauj khoom, tsheb chassis, thiab cov tsheb thauj khoom. Nws cov kev ua kom zoo dua tsis kam them tus nqi tswj los ntawm 30-50% nyob rau hauv cov nag, cov khoom daus, thiab kev pabcuam dej haus kom deb li 20-30 xyoos.
Choj Engineering-} Tsim nyog rau ntev- spail vidges, thiab kev tsheb nqaj hlau loj- Term loads thiab atmospheric corrosion. Piv rau cov hlau zoo tib yam, cov choj yuav tsum tau tshaj 50% tsawg dua los tiv thaiv- Cov teeb meem corrosion thaum lawv lub neej thiab muaj peev xwm ntev tshaj 50 xyoo.
Ntauwd qauv{{0-}} xob siv nyob rau hauv kev hloov cov yees thev naus laus zis, thiab cua lub zog yees. Nws cov ntaub ntawv ruaj khov los ntawm 6-12 lub hlis, txo qis txij nkawm xav tau thiab ua rau nws siab} {cua, thiab thaj chaw ntug hiav txwv.
Ntim thiab Cov Khoom Siv Thauj Khoom{{0- Nyob rau hauv Maritime ib puag ncig, cov pa roj carbon steel hlau feem ntau li 10-15 xyoo. Cov thawv tau ua los ntawm 09Cupire - b steel daim txuas ntxiv lub neej rau 20-30 xyoos, ua kom dej hiav txwv thiab tsis muaj ntsev.
Muaj Chaw Muaj Vaj Tse Thiab Fluue Roj Roj- phosphorus ntxiv rau qhov ntau dua 09cupire- b corrosion rolic flu de acidic flue gas ib puag ncig. Haum rau cov pa taws, Boiler cov thoob, thiab tso tsheb hlau luam chemical, nws txuas ntxiv lub neej los ntawm 15-2-25 xyoos.
Architecture thiab Toj roob hauv pes Engineering- Nws ib txwm tsim cov xeb patina- xim haue, ua kom sib xyaw ua ke nrog kev hais kom zoo nkauj. Feem ntau siv nyob rau hauv cov phab ntsa Rhuav, duab puab, toj roob hauv pes, thiab kev sib sau pej xeem, nws tswj hwm kev ua kom zoo nkauj rau 40-80 xyoo.
