1. Dab tsi yog ovtm 519 1015 cov yeeb nkab steel?
A: AFTM A519 yog ib tus qauv tsim los ntawm cov neeg Asmeskas cov khoom lag luam (ASTM) uas yog ib qho kev lag luam steel hlau thiab cov khoom siv roj carbon monoxide qis dua li 0.15%. Nws muaj kev zoo heev ntawm kev muag khoom thiab weldability thiab feem ntau siv hauv cov neeg kho tshuab cov txheej txheem, cov tshuab siv hydraulic, thiab lwm yam kev siv.
2. Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv neeg ua haujlwm rau 1015 tus yeeb nkab steel?
A:
Tshuaj lom neeg muaj pes tsawg leeg (%):
Cov pa roj carbon (c) Tsawg dua lossis sib npaug rau 0.15, manganese (mn) 0.30-0.60, posphorus (p) tsawg dua lossis sib npaug rau 0.050.
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab (Cov nqi raug):
Tensile lub zog ntau dua los yog sib npaug rau 380 MPa, tawm suab ntau dua lossis sib npaug ntawm phab ntsa tuab)} Dab tsi yog qhov sib txawv ntawm A519 thiab lwm yam kav hlau (xws li A106)?
A519: Tsim tshwj xeeb rau cov ntawv thov kho tshuab (xws li Shafts thiab lub zog), nws hais txog qhov chaw raug thiab sab nrauv thiab ib txwm ua tiav.
A106: Siv rau kev kub kub thiab cov raj roj siab siab (xws li rhaub dej tsis taus thiab lub siab} Cov yeeb nkab muaj zog, vim tias nws cov pa roj carbon ntau, yog tsis haum rau cov pa hluav taws kub.
4. Nws cov ntawv thov tseem ceeb dabtsi?
A519: Cov tshuab kho tshuab: Shafts, sib txuas cov pas nrig, thooj voos kheej sib txuas, thiab lwm yam.
Cov Txheej Txheem Automotive: cov qauv kev ntxhov siab tsawg.
Kev tsim kho dav dav: cov khoom siv sib zog, conveyor chais, thiab lwm yam.
Tsis pom zoo rau kev siv nyob rau hauv corrosive ib puag ncig lossis cov ntawv thov thauj khoom siab (xim saum npoo lossis alloy steel yuav tsum tau).
5. Machining thiab Vuam ceev faj?
A519: Machining: Yooj yim txiav, tab sis zam dhau kev ua haujlwm txias ntau dhau (qeeb kev txiav ceev ceev yog pom zoo).
Vuam: Haum rau txhua txoj kev sib tw vuam txoj kev (xws li arc vuam thiab mig vuam). Preheard tsis tas yuav tsum tau, tab sis kev ua txhaum saum npoo av yuav tsum tau los tiv thaiv porosity.
