GR12 Qws Hlau Sheet Pipe Cov yam ntxwv thiab cov qauv siv
1. Taw qhia:
GR12 (Ti-0.3Mo-0.8Ni) titanium alloy yog corrosion-resistant titanium alloy. Nws yog ib qho ze-alpha alloy tsim los txhim kho qhov kev txhim kho corrosion ntawm titanium ntshiab. Cov alloy muaj 0.3% Mo thiab 0.8% Ni, uas tsis yog tsuas yog ntxiv dag zog rau cov hlau, tab sis kuj muaj cov crevice corrosion kuj zoo rau qhov kub thiab txias, pH chlorides tsawg lossis tsis muaj zog acids. Nws cov corrosion kuj yog qhov zoo dua li cov ntshiab titanium thiab ze rau GR7 alloy. GR12 alloy kuj muaj cov txheej txheem zoo plasticity thiab vuam zog, thiab tau siv dav hauv kev lag luam tshuaj. Cov hlau yog muaj nyob rau hauv cov mob annealed thiab cov khoom tseem ceeb muaj xws li daim hlau, rods, raj, forgings thiab hlau rods. Zoo sib xws txawv teb chaws hom Gr.12 (USA).

3. Alloy khoom:
Qhov ceev yog 4.54g / m3, elastic modulus nyob rau hauv chav tsev kub yog 103 ~ 107GPa, hardness yog HB180 ~ 215, thiab theem hloov point yog 890 ± 15 degree.
Corrosion kuj: Nickel txhim kho qhov crevice corrosion kuj ntawm titanium nyob rau hauv hydrochloric acid tov, tab sis nyob rau hauv txo acids, corrosion kuj ntawm titanium-nickel alloy yog qis dua cov ntshiab titanium. Tsim nyog ntxiv ntawm molybdenum rau Ti-Ni alloy tuaj yeem txhim kho nws cov corrosion kuj hauv kev txo cov xov xwm.
