GR2 titanium khoom yog dab tsi?
Titanium Qib 2 (GR2, UNS R50400, W.Nr. 3.7035)yog siv rau vuam ua lag luam ntshiab titanium, qhov twg tsis muaj qhov hnyav, siab corrosion kuj thiab zoo txhua yam muaj zog yog qhov tseem ceeb.
Cov khoom siv muab tub lim no yog tshwj xeeb tshaj yog tsim rau cov ntawv thov hauv marine ib puag ncig, tshuaj txheej txheem kev lag luam thiab kev kho mob engineering cov qauv.
Lub vuam hlau tso nrog Titanium GR2 muaj kev tiv thaiv zoo rau dej hiav txwv, chlorides, acids thiab lwm yam corrosive xov xwm, thaum tuav siab toughness thiab formability. Cov khoom siv yog biocompatible, ua rau nws haum rau vuam kev kho mob cog thiab khoom siv.
Lub vuam hlau los ntawm Titanium GR2 tsis yog hardenable los ntawm kev kho cua sov thiab nthuav tawm tib lub siab corrosion kuj zoo li lub hauv paus hlau. Nws yog siv thoob plaws ntiaj teb hauv kev lag luam xws li offshore, aerospace, lub zog thiab lub zog tsim hluav taws xob, thiab kev lag luam roj thiab roj, qhov chaw ua haujlwm kev ntseeg siab thiab kev ua haujlwm ntev yog qhov tseem ceeb.
Qhov sib npaug ntawm Qib 2 titanium yog dab tsi?
Tsim los ntawm UNS R50400, ASTM Qib 2 titanium (kev lag luam ntshiab titanium) muaj ntau qhov sib npaug thoob ntiaj teb uas suav nrog DIN 3.7035 (German), GOST BTI-0 (Lavxias teb sab), BS 25-35t / hauv2(British), JIS Class 2 (Japanese), Gr. TA2 (Suav GB). Lawv cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab tau teev tseg hauv qab ob lub lis piam.

Qhov txawv ntawm Gr2 thiab Gr5 Titanium yog dab tsi?
Titanium Gr2 thiab Gr5Feem ntau txawv ntawm lub zog, corrosion kuj, workability, thiab nqi. Gr2 yog cov khoom lag luam ntshiab titanium nrog lub zog tensile ntawm 344 MPa, muab kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv marine thiab tshuaj ib puag ncig. Nws kuj yog qhov hnyav thiab yooj yim rau kev tsim thiab vuam, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev tsim khoom yooj yim thiab ntev - lub sij hawm durability nyob rau hauv corrosive tej yam kev mob.
Hauv qhov sib piv, Gr5 (Ti-6Al-4V) yog cov hlau uas muaj 6% txhuas thiab 4% vanadium, uas ua rau nws muaj zog (1000 MPa tensile zog) thiab qaug zog. Qhov no ua rau Gr5 zoo tagnrho rau aerospace, tsheb, thiab kev siv kho mob, qhov twg yuav tsum muaj kev ua haujlwm siab thiab ua haujlwm ntev. Txawm li cas los xij, Gr5 yog kim dua thiab me ntsis nyuaj rau lub tshuab vim nws cov ntsiab lus alloying ntxiv.
Gr2 yog qhov zoo tshaj plaws rau kev tiv thaiv corrosion thiab yooj yim fabrication, thaum Gr5 yog qhov zoo tagnrho rau siab - kev siv zog xws li aerospace thiab tsheb.
