4Cr13 steel (Lub npe tshiab: 40Cr13) yog ib hom martensitic stainless hlau, uas muaj hardness siab dua3Cr13 steeltom qab quenching. Cov hlau muaj kev ua haujlwm zoo txhua yam. Tom qab kev kho cua sov (quenching thiab tempering), nws muaj corrosion kuj zoo, polishing kev ua tau zoo, siab zog thiab hnav tsis kam.

Mechanical Properties rau Steel Bars
- HRC hardness: Ntau dua lossis sib npaug rau 50 (Quenched thiab Tempered)
- HBW hardness: Tsawg dua los yog sib npaug rau 235 (Annealed)
Lus Cim: Rau txoj kab uas hla lossis thickness Tsawg dua lossis sib npaug li 75 hli.
Lub cev muaj zog
- Qhov ceev (g / cm3): 7.75
- Lub peev xwm kub tshwj xeeb (J / Kg·K): 460 ntawm 0-100 degree
- Thermal conductivity (W / m·K):
- 28.1 ntawm 100 degree
- 28.9 ntawm 500 degree
- Coefficients ntawm linear thermal expansion (10-6/K):
- 10.5 ({2}} degree)
- 12. 0 (0-500 degree)
- Hluav taws xob tiv thaiv (μΩ·m): 0.59 ntawm 20 degree
- Longitudinal modulus ntawm elasticity (kN / mm2): 215 ntawm 20 degree
Kev kho cua sov
- Annealing: 800 - 900 degree (Slow txias)
- quenching: 1050 - 1100 degree (roj txias)
- Tempering: 200 - 300 degree (Cua txias)
Forging
Roj quenching txias ua hauj lwm tuag steel muaj qee qhov tawg rhiab heev. Nws yuav tsum tsis txhob rhuab sai sai thaum forging cua sov. Nws yog qhov zoo dua rau preheat ntawm 650-750 degree . Lub forging cua sov kub yog 1130-1150 degree, thiab qhov kawg forging kub yuav tsum siab tshaj 800-850 degree . Qhov ntsuas kub siab tshaj plaws yog noj thaum lub ingot yog forged, thiab qhov ntsuas kub qis dua yog noj thaum lub billet yog forged.
