Yog tias koj tab tom nrhiav kev ntseeg siabASTM A588 weathering steel rawsrau cov choj, kev tsim vaj tsev, khoom siv thauj mus los, thiab cov haujlwm sab nraum zoov, peb muab ASTM A588 C channels thiab U channels tsim rau ASTM cov qauv.
ASTM A588 channel steel yog siab -lub zog qis- alloy (HSLA) huab cua hlau uas muaj tooj liab (Cu 0.20% - 0.40%), chromium (Cr 0.40% - 0.65%), thiab nickel (Ni 0.25% - 0.50%). Cov ntsiab lus no tsim cov txheej txheem patina ruaj khov, txhim kho atmospheric corrosion kuj.
Nws daws tau cov teeb meem zoo xws li xeb, kev saib xyuas tsis tu ncua, txheej tsis ua haujlwm, thiab txo cov kev pab cuam lub neej pom hauv cov pa roj carbon zoo tib yam.
Piv nrog rau A36 steel, ASTM A588 muaj 2-4 npaug zoo dua corrosion kuj, kev pab cuam lub neej ntev ntawm 20-50 xyoo nyob rau hauv sab nraum zoov ib puag ncig, thiab 30% -70% txo nqi tu, ua rau nws zoo tagnrho rau cov choj, railways, ports, hnyav tsheb, thiab sab nraum zoov steel qauv.
ASTM A588 channel steel yog tsim nyob rau hauv kev tswj cov txheej txheem nruj nruj kom paub meej qhov ntev, ncaj, thiab hla -sectional stability rau ob qho tib si C thiab U channels. Kev ncaj ncaj yog feem ntau tswj tsis pub dhau tsawg dua lossis sib npaug li 1.5 mm / m, thaum qhov ntev ntev yog feem ntau nyob rau hauv ± 2% lossis ± 2.5 mm (qhov twg yog qhov tsawg dua), ua kom ntseeg tau tias haum- nce hauv loj - nplai steel qauv sib dhos.
Qhov kev ruaj ntseg qhov ntev no pab txo cov teeb meem kev teeb tsa xws li misalignment, kev sib txawv ntawm kev sib txuas, vuam kev ntxhov siab, thiab ntawm -qhov chaw rov ua haujlwm los ntawm kev hloov pauv ntawm ntu. Nws kuj tseem txhim kho kev tsim kho kom zoo los ntawm kev txo cov kev txiav thiab kev hloov kho, ua kom tag nrho kev teeb tsa ua haujlwm tau zoo li ntawm 15% -25%.
ASTM A588 channel steel nta ruaj khov kho cov cuab yeej tswj, nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm tsis pub tsawg dua 345 MPa. Nws muab siab load- bearing muaj peev xwm thaum tuav zoo toughness thiab formability.
Qhov no zoo tiv thaiv cov teeb meem xws li brittle cracking tshwm sim los ntawm cov khoom hardness ntau dhau thiab deformation instability uas tshwm sim los ntawm lub zog tsis txaus. Yog li ntawd, nws ua kom ntseeg tau cov qauv kev nyab xeeb nyob rau hauv ntev - lub sij hawm thauj khoom sab nraud thiab ib puag ncig kev ntxhov siab.
