I. Khoom Paub meej
GR12 titanium alloy phaj yog cov khoom siv hlau zoo uas muab kev ua haujlwm sib luag. Nws muaj tseeb muaj pes tsawg leeg ntawm Ti-0.3Mo-0.8Ni ho txhim khu lub zog thiab corrosion kuj thaum tuav lub zoo machinability ntawm industrial ntshiab titanium, tshwj xeeb tshaj yog zoo nyob rau hauv chloride ib puag ncig. Rau cov ntawv thov uas xav tau qhov sib npaug ntawm kev tiv thaiv corrosion thiab lub zog, GR12 yog qhov kev xaiv zoo tshaj plaws.
1.Chemical Properties (Material Specification)
2. Lub cev muaj zog
Tensile Strength: Ntau dua lossis sib npaug li 485 MPa
Ceev: 4.51 g / cm³ (kwv yees li 60% steel)
Yield zog: Ntau dua lossis sib npaug rau 345 MPa
Elongation ntawm So: Ntau dua lossis sib npaug li 30%
II. Txheej txheem ntau lawm
Annealing Pre-kev kho mob: Kub- cov nplooj ntawv dov tau muab tso rau ntawm 700-750℃rau 2 teev, ua raws li cov cua txias kom txo tau cov kev ntxhov siab sab hauv los ntawm kub dov thiab kho cov yas yas.
Ntau- dhau Cold Rolling: Ua nyob rau hauv chav tsev kub nrog 20-30% deformation ib kis. Tag nrho ntawm 3-5 dhau mus zuj zus txo cov ntawv tuab rau qhov tseem ceeb (0.3-10 hli). Rolling ceev: 2-5 m / s. Rolls xav tau kev kho polishing.
Intermediate Annealing: Tom qab txhua 2-3 qhov txias dov dhau, rov ua 700-750℃annealing txheej txheem los tiv thaiv cov kab nrib pleb los ntawm kev ua hauj lwm hardening.
Thaum kawg Txias Rolling: Tswj qhov deformation tus nqi ntawm qhov kawg dhau ntawm 15-20% kom ntseeg tau tias qhov roughness Ra tsawg dua los yog sib npaug rau 0.8μm thiab qhov ntev ntev raws li cov lus qhia.
Cov Ntsiab Cai Tswjfwm
Kev Tswj Kub Kub: Tsis txhob siab tshaj 980℃thoob plaws qhov cua sov kom tiv thaiv -theem nag lossis daus thiab corrosion kuj degradation. Ua ntej- txias dov annealing kub yuav tsum tsis txhob siab dhau heev lawm los tiv thaiv coarse grain tsim.
Kev Tswj Deformation: Ib zaug -dhau deformation yuav tsum tsis txhob ntau tshaj 50%, nrog rau cov deformation nce mus txog 70-80% kom sib npaug efficiency thiab formability.
Kev Tiv Thaiv Qhov Nto: Ua haujlwm argon lossis nitrogen gas shielding thaum kub dov los tiv thaiv oxidation nto ua TiO₂. Tshem tawm kub- dov nto nplai ua ntej txias dov (los ntawm kev sib tsoo los yog kua qaub).
III. Daim ntawv thov Case
Chemical Engineering: Reactors, heat exchangers, piping systems (acid thiab alkali corrosion resistance)
Offshore Engineering: Desalination nroj tsuag, offshore platform khoom (chloride ion corrosion kuj)
Kev Kho Mob: Orthopedic implants (hip thiab lub hauv caug hloov)
Roj thiab Gas: Roj thiab roj pipelines, offshore drilling khoom
Aerospace: Lub teeb yuag structural Cheebtsam, siab -kub qhov chaw
Kev Ua Zaub Mov: Corrosion-cov khoom siv kab ntau lawm
Cim npe nrov: Qib 12 titanium alloy nyias daim ntawv, Tuam Tshoj qib 12 titanium alloy nyias daim ntawv manufacturers, lwm tus neeg, Hoobkas
