Ncaj ncees:Tsawg dua los yog sib luag rau 0.5-2.0 mm / m ib txwm; Kev tswj nruj rau cov kev xav tau.
Deg tas:Mill nplai, tev, tev & roj, muab, av & polished, lossis tiv thaiv txheej (VCI roj).
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab (Raug, Qib & Tshav Kub Kub- Kev Kho Mob)
Paib lub zog:~ 235 - {{700+ MPa (nyob ntawm qib thiab kev kho cua sov).
Lub zog tensile:~ 360 - 1000 MPa.
Elongation:8-25% (nws txawv ntawm qib).
Hardness:Teev rau ib daim ntawv thov; annealed → qes tawv rau machining; Quenched & Tempered → Hardness Hardness / Toughness.
(Muab cov qhab nia qhia meej thiab muaj mob kom tau txais cov khoom ntiag tug.)
Qhov hnyav suav (siv tau sai)
Pawg ib meter ib meter (kg / m) rau cov square square bar (hlau, ntom ≈ 7.85 t / m³):
Mass (kg / m)=(sab hauv hli) ² × 0.00785
Cov Qauv Qhov hnyav:
50 ntsis 50 hli → 50² ×0.00785 =19.625 KG / M
100 × 100 hli → 100 × 0.00785 =78.50 kg / m
200 × 200 hli → 200 {0.00785 =314.00 kg / m
400 × 400 hli → 400 ×0.00785 =1,256.00 KG / M
