Hauv kev muaj fabrication, precision nyob rau hauv cov khoom specifications yog tsis - sib yeem. Rau cov tub txawg ua haujlwm nrog daim ntawv hlau, nkag siab qhov tseeb tuab ntawm 14 ga steel yog qhov kev kwv yees tus nqi, kev kwv yees cov qauv kev ua haujlwm. Kab lus no muab txoj kev ntsuas nruj ntawm 14 - goose} goose} goose} goose} goose} pakee cov khoom siv, ntsuas kev ntsuas, thiab cov ntawv thov tiag tiag.
Txhais "Kev Hlub" (GA)
Lo lus "ntsuas" (GA) keeb kwm ntawm tus naj npawb ntawm ib daim ntawv dhau los ntawm cov mills kom ua tiav lub hom phiaj tuab. Niaj hnub no, nws sawv cev rau qhov ntsuas kev ntsuas sib txawv:
- US tus qauv ntsuas: Govards Stainless hlau, Aluminium, thiab tooj dag (ATM A480)
- Cov Khoom Siv Khoom Siv Khoom Siv Hluav Taws Xob: Siv rau cov hlau roj carbon hlau (ASTM A36)

14 Ga Hlau Nyhav Xam
Nyhav ncaj ncaj ncaj qha nrog cov tuab thiab cov khoom ntom ntom ntom. Rau cov hlau tsis muaj zog (ntom ntom: 0.289 lb / nyob rau hauv):
Qhov hnyav (LB / ft²)=(tuab × 144 in² / ft² × density)
14 ga ss=(0.0781 × 14489)=3.25 lb / ft² (15.86 kg / m²)
Vim li cas xaiv 14 ga steel
Txheej Txheem Txheej Txheem
- 14 ga stainless hlau withstals 42,000 psi tensile kev ntxhov siab (hom 304)
- 30% Ntau dua cov neeg qaug zog tsis kam vs . 16 ga hauv kev co-} hom ntawv thov
Txwv Fabrication Txwv
- Qhov tsawg kawg nkaus khoov radius: 1.5 × tuab (0.117 "rau ss)
- Punch Clearance: 12-15% ntawm tuab
Corrosion Allowance
- Muab 2.5 × kev pab ntev ntev vs . 16} ga hauv chloride ib puag ncig (piv txwv li, cov ntawv thov marine)

14 GA steel muab cov kev sib npaug ntawm lub zog (0.0781 "rau kev ua kom muaj txiaj ntsig / 1.984 mm), thiab tus nqi} Cov ntaub ntawv tso tawm hauv nruab nrab. Thaum hais cov ntaub ntawv qhia:
Rau corrosion Kuj: xaiv 14 ga hom 316 stainless
Rau cov txheej txheem rigidity: xaiv 14 ga A572 Cov Hlau Hlau
Rau qhov hnyav Txuag nyiaj: xav txog 14 ga aluminium 5052-h32
Yuav tsum tau siv tam sim no ASTM cov qauv thiab pov thawj zeb ntawv pov thawj zeb. Nco ntsoov: GA lej qhia pom Nominal tuab - ntsuas ntsuas nrog ntsuas micrometers nyob twj ywm rau qhov tsis tseem ceeb rau kev ua kom ncaj.
