Seamless steel yeeb nkab(4130 steel yeeb nkab) chromium-molybdenum alloy steel yeeb nkab rau tsheb yob tawb
AISI 4130 domestic hom 30CrMo yog cov hlau alloy uas muaj chromium thiab molybdenum. Lub zog tensile feem ntau yog siab dua 750MPa. Dab tsi yog pom nyob rau hauv kev ua lag luam yog cov tuav thiab cov phaj tuab. Nyias-walled 4130 steel kav yog siv los ua lub tsheb kauj vab ncej. IA thiab Tuam Tshoj Automobile Federation cov kev cai ntawm steel yeeb nkab cov ntaub ntawv rau kev sib tw yob tawb: txias-draw seamless steel kav.
4130 alloy steel yeeb nkab muaj carbon 0.26 ~ 0.34, silicon 0.17 ~ 0.37, manganese 0 .40~0.70, molybdenum 0.15 ~ 0.25, chromium 0.80 ~ 1.10. 4130 yog sib npaug rau Japanese SCM430. Cov hlau no muaj zog thiab tawv, siab hardenability, thiab qhov tseem ceeb hardenable txoj kab uas hla ntawm roj yog 15-70mm. Cov hlau tseem muaj lub zog thermal zoo, nrog lub zog kub txaus hauv qab 500 degree, tab sis lub zog poob qis heev ntawm 550 degree.
Mechanical cwj pwm:
Tensile zog: 85, 000 - 105, 000 psi
Yield zog: 70, 000 - 90, 000 psi
Elongation: 20-30%
daim ntawv thov:
4130 steel yeeb nkab muaj kev siv ntau yam kev lag luam, suav nrog:
Aerospace: Siv los tsim cov khoom siv dav hlau xws li tsaws iav, cov khoom siv, thiab cov khoom siv cav.
Automotive: Feem ntau siv hauv kev tsim cov khoom sib tw, chassis thiab ncua kev kawm ntawv.
Roj thiab Roj: Siv los tsim cov khoom siv rau kev lag luam roj thiab roj, suav nrog cov cuab yeej downhole thiab tubing. Vim nws lub zog thiab versatility, nws yog haum rau ntau yam qauv thiab txhua yam kev siv. 4130 steel muaj qhov zoo weldability thiab tuaj yeem yooj yim welded siv cov txheej txheem vuam. Cov hlau tuaj yeem raug kho kom sov kom tau txais cov khoom siv kho mob uas xav tau, xws li muaj zog ntxiv.
