30CrmMnsi Hloov Hlau (GB / T 3077) yog qhov siab- Lub zog alloy nrog cov khoom siv mechans nrog rau aerospace raseners:
Tensile Lub zog: 1080-1320 MPA tom qab quenching (880 degree) thiab ua kom muaj zog (540 degree), kom muaj peev xwm tiv taus heev rau hauv cov qauv dav hlau.
Tos lub zog: ntau dua los yog sib npaug rau 880 MPa, muab clamping clamping lub zog yam tsis muaj kev sib txawv.
Kev Cuam Tshuam Cov Khoom Siv: Loj dua lossis sib npaug nrog 39 J ntawm 20℃(Charpy V {{Next} Itch cia li thauj khoom sai thaum lub sijhawm hle thiab tsaws.
Quab zog dag zog: ntau dua los yog sib npaug rau 530 MPa rau 10⁷ mus rau 10⁷ mus, tseem ceeb rau cov fasteners kom dhau ib txhiab ntawm lub davhlau mus.
Nws cov chemical (0.27-0.34% c, 1.00-1.30% thiab yog siv tshuab hluav taws xob thiab siv tau rau {{} hauv {{11 {11 11 {}}}}}}}} Cov npe qhia txog nws "Aerospace {{}}} qhov muaj zog."
