ASME SB265 Qib 23 (Ti-6Al-4V ELI) Titanium Alloy Phaj
Oct 23, 2025
ASME SB265 Qib 23: Kev Pom Zoo
ASME SB265 yog lub siab- nkoj saws ntawm ASTM B265, npog titanium thiab titanium alloy sawb, ntawv, thiab phaj rau boiler thiab siab- nkoj kev pabcuam. Qib 23 (Ti-6Al-4V ELI, UNS R56407) yog qhov ntxiv-tsawg-interstitial version ntawm workhorse 6Al-4V alloy. Kev tswj nruj ntawm cov pa oxygen, nitrogen, hydrogen, thiab hlau muab Qib 23 ntau dua pob txha toughness thiab ductility ntau dua li Qib 5, ua rau nws tsim nyog rau cov qauv hauv hiav txwv, cov khoom siv hauv aerospace, cov hlab ntsha siab, thiab cov khoom siv phais.
Tshuaj muaj pes tsawg leeg
| Element | Limit (wt%) |
|---|---|
| Aluminium | 5.5-6.5 |
| Vanadium | 3.5-4.5 |
| Hlau | Tsawg dua lossis sib npaug li 0.25 |
| Oxygen | Tsawg dua lossis sib npaug li 0.13 |
| Cov pa roj carbon | Tsawg dua lossis sib npaug li 0.08 |
| Nitrogen | Tsawg dua los yog sib npaug li 0.05 |
| Hydrogen | Tsawg dua lossis sib npaug li 0.012 |
| Titanium | Tshuav |
Mechanical Properties (Annealed)
| Khoom | Tus nqi |
|---|---|
| Tensile zog | Ntau dua lossis sib npaug rau 860 MPa |
| Yield zog, 0.2% offset | Ntau dua lossis sib npaug li 795 MPa |
| Elongation | Ntau dua lossis sib npaug li 10% |
| Qhov ntom | ≈ 4.43 g / cm³ (4.42-4.51 yam) |
| Hardness (annealed) | ≈ 30-34 HRC (tseem ceeb, qhia) |
Hardness tau tshaj tawm raws li cov ntaub ntawv raug; kev lees txais yog raws li cov khoom tensile tau teev tseg hauv tus qauv. Cov mob annealed yog lub xeev cov khoom siv ib txwm muaj rau phaj, ntawv, thiab sawb.
Qhov ntom ntom thiab muaj zog tshwj xeeb
Qib 23 muaj qhov ntom ntom ntawm 4.43 g / cm³, kwv yees li 56% ntawm cov qauv hlau. Nrog lub zog tensile yam tsawg kawg nkaus ntawm 860 MPa, nws lub zog tshwj xeeb (lub zog tensile muab faib los ntawm qhov ceev) yog li 194 MPa·cm³ / g, kwv yees li peb zaug ntawm austenitic stainless hlau phaj, uas feem ntau muaj txog 520 MPa ntawm 7.9 g / cm³ (lub zog tshwj xeeb ze 66). Qhov kom zoo dua no ua rau kom txuag tau qhov hnyav hauv cov qauv hauv ntug dej hiav txwv, dav hlau, thiab cov cuab yeej siv siab uas txhua kilogram suav.
Daim ntawv thov
Marine thiab offshore structures - seawater resistance thiab low weight
Cov hlab ntsha siab thiab cov khoom siv hluav taws xob sib txawv hauv cov kev pabcuam chloride
Aerospace structural phaj xav tau siab toughness
Kev kho mob implant blanks, muab ntxiv rau ASTM F136
Cov lus nug nquag
Dab tsi yog qhov txawv ntawm ASME SB265 thiab ASTM B265?
ASME SB265 txais ASTM B265 rau hauv ASME Boiler thiab Pressure Vessel Code; cov khoom yuav tsum tau zoo ib yam, thiab SB- ntawv pov thawj phaj raug lees txais rau siab- nkoj tsim.
UNS R56407 txheeb xyuas dab tsi?
UNS R56407 yog tus lej sau npe rau Ti-6Al-4V ELI (Qib 23) hauv Kev Sib Koom Tes Tus lej; R prefix qhia txog titanium lossis reactive hlau.
Puas yog tus nqi hardness yog qhov yuav tsum tau ua?
Tsis yog. Hardness qhov tseem ceeb xws li 30-34 HRC yog cov nqi annealed ib txwm siv; kev lees txais yog nyob ntawm tensile thiab chemistry yuav tsum tau nyob rau hauv tus qauv.
Vim li cas qib 23 sib zog dua hlau rau tib lub zog?
Nws qhov ceev yog li 4.43 g / cm³ piv rau 7.85 g / cm³ rau cov hlau, thaum nws qhov tsawg kawg nkaus tensile lub zog ntawm 860 MPa yog deb tshaj li cov qauv hlau, muab kwv yees li peb zaug ntawm lub zog tshwj xeeb.
SB265 Qib 23 phaj tseem tuaj yeem siv rau kev cog qoob loo?
Tau rau chemistry, tab sis cov ntawv cog lus cog ntxiv yuav tsum tau ntawv pov thawj rau ASTM F136 lossis ISO 5832-3, suav nrog kev cog lus tshwj xeeb traceability thiab kuaj.
