Cov txheej txheem tswj hwm huab cua zoo li cas?
1. Kev lees paub thoob ntiaj teb cov qauv khoom siv
Weathering steel zoo yog tswj hwm los ntawm ntau yamzoo-tsim qauv thoob ntiaj teb, kom ntseeg tau tias kev ua haujlwm zoo ib yam thiab corrosion kuj. Cov qauv siv feem ntau suav nrogASTM A588 / A242 (Tebchaws Asmeskas), TS EN 10025-5 (Tebchaws Europe), JIS G3125 (Nyiv), thiabGB/T 4171 (Tuam Tshoj). Cov qauv no qhia meej meej cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov khoom xa tuaj.
2. Tshuaj lom neeg muaj pes tsawg leeg thiab kev tswj cov alloy
Tag nrho cov qauv qhia kev tswj xyuas ntxiv ntawm cov ntsiab lus tseem ceeb alloying xws litooj liab, chromium, nickel, thiab phosphorus, uas yog qhov tseem ceeb rau kev tsim kom muaj kev ruaj ntseg tiv thaiv patina. Cov kev txwv tshuaj nruj nruj kom ntseeg tau tias cov huab cua steel tsim kev tiv thaiv corrosion tsis zoo thiab kev kwv yees ntev ntev - tus cwj pwm nyob thoob plaws ib puag ncig sib txawv.
3. Mechanical Properties thiab Test Requirements
Weathering steel qauv kuj tswjyield zog, tensile zog, elongation, thiab cuam tshuam toughness. Kev sim yuav tsum tau- suav nrog kev sim tensile, Charpy qhov kev sim cuam tshuam, thiab kev tshuaj xyuas qhov ntev- xyuas kom meej tias cov khoom ua tau raws li cov qauv tsim thiab kev nyab xeeb rau cov choj, vaj tse, thiab cov phiaj xwm kev tsim kho.
4. Kev Ua Haujlwm Zoo thiab Kev Tshawb Fawb
Certified weathering steel yog muab nrogDaim ntawv pov thawj zeb xeem (MTC), kub tooj, thiab tag nrho traceability. Cov ntaub ntawv no muab cov neeg yuav khoom muaj kev ntseeg siab hauv cov khoom hauv paus, kev ua raws cai, thiab sib xws, ua kom yooj yim pom zoo los ntawm engineers thiab tus tswv qhov project thaum txo kev pheej hmoo ntawm kev yuav khoom.
