ASTM A671 CC65 CL 12 EFW Cov Kav Hlau: Cov Kav Hlau Uas Muaj Zog Siab Rau Cov Ntawv Siv Hauv Kev Lag Luam

ASTM A671 CC65 CL 12 EFW yeeb nkabyog cov yeeb nkab EFW zoo siv dav hauv roj, roj av, tshuaj lom neeg, thiab cov kav dej kev lag luam dav dav. Cov yeeb nkab no ua tau raws li qhov yuav tsum tau ua ntawmASTM A671 cov qauvthiab tau tsim los rau kev thauj cov kua dej nruab nrab thiab siab thiab cov ntawv thov kev tsim kho. Lawv muaj kev sib txuas zoo heev thiab cov khoom siv kho tshuab, ua rau lawv zoo tagnrho rau kev tsim kho kav dej hauv kev lag luam.

Cov Khoom Siv Qhia Txog

Cov kav dej yog tsim los ntawm cov hlau tsis tshua muaj zogLub zog siab CC65 hlau, cov tshuaj lom neeg sib xyaw ua ke raug tswj hwm kom zoo tshaj plaws los muab kev sib txuas zoo tshaj plaws, kev tiv thaiv corrosion thiab kev kub siab. Cov hlau muaj cov qauv nplej sib xyaw thiab ua tiav cov qauv siab thiab kev xav tau siab hauv kev lag luam.

Cov Tshuaj Lom Zem

Cov Tshuaj Lom Zem (Cov Nqi Ib Txwm Muaj)
Khoom Cov pa roj carbon (C) Manganese (Mn) Silicon (Si) Sulfur (S) Phosphorus (P) Nickel (Ni) Chromium (Cr) Tooj liab (Cu)
Cov ntsiab lus (%) 0.12–0.20 0.50–1.00 0.10–0.35 ≤0.035 ≤0.035 ≤0.25 ≤0.25 ≤0.25

Lus Cim: Cov tshuaj lom neeg tiag tiag yuav txawv me ntsis rau ib pawg tab sis yeej ib txwm ua tau raws li ASTM A671 CC65 CL 12 cov qauv.

Cov Khoom Siv Kho Tshuab

Vaj tse Tus nqi
Lub zog tensile 415–550 MPa
Lub Zog Tawm ≥280 MPa
Kev ntev ≥25%
Kev Cuam Tshuam Toughness Muaj kev sim cuam tshuam rau qhov kub qis uas ua raws li tus qauv, xaiv tau

Cov ntawv thov

ASTM A671 CC65 CL 12 EFW cov kav hlau feem ntau siv rau hauv:
