ST52-3 Hlau - Zoo Weldability
hlau phajKhoom Taw Qhia
1. Taw qhia rau ST52-3 steel phaj cov ntaub ntawv:
ST52-3 yog sib npaug rau qib Q345, (16mn) St52-3 cov khoom siv tshiab: 1.0570, cov khoom qub: 1.0841. St52-3 yog tus cwj pwm los ntawm nws lub zog tensile thiab qhov taw tes tawm los. St52-3 yog cov hlau tsis tshua muaj hlau muaj zog. Cov qib steel yog tsim los ntawm St, tus yam ntxwv tus nqi ntawm cov hlau thiab qhov ntsuas zoo. Muaj cov hlau nrog cov txheej txheem deoxidation xaiv. Cov cim sib thooj (U lossis R) tau muab tso rau pem hauv ntej ntawm qib steel. Muaj cov hlau tshwj xeeb xws li: USt52-3 lossis RRSt37-2. ST52-3 steel phaj sib haum rau lub teb chaws tus qauv Q355, thiab cov txiaj ntsig tensile kev ua tau zoo ntawm ST52-3 raug tshuaj xyuas.
2. Cov qauv txheej txheem thiab kev kho cua sov ntawm ST52-3 steel phaj cov ntaub ntawv:
ST52-3 steel phaj belongs rau German tus qauv qis-alloy steel, thiab tus qauv siv yog DIN17100. Cov khoom siv raws li tus qauv DIN yog: ST37-2, STE355, STE460, thiab lwm yam. Kev kho cua sov ntawm ST52-3 steel phaj: kub dov, tswj dov, normalizing.
ST52-3 steel phaj siv cov qauv txheej txheem DIN17100, uas yog ze rau lub teb chaws tus qauv Q355B kev ua haujlwm.
3. ST52-3, ST52-3-Z25, ST52-3-Z35, Z15, Z25, thiab Z35 txhais li cas:
ST52-3 yog Z-kev taw qhia kev ua tau zoo steel, Z-kev taw qhia yog cov thickness kev taw qhia ntawm cov hlau phaj, thiab Z-kev taw qhia yog ib tug lamellar tearing resistance test ntawm cov hlau phaj. Cov qib yog teem los ntawm siab mus rau qis li Z35, Z25, thiab Z15.
