Khoom Description
Vim li cas thiaj xaiv ASTM A108 Chromoly Square Tube?
- Piv nrog cov raj puag ncig, cov raj square muaj qhov ruaj khov hauv zos, thiab txoj cai - lub kaum sab xis tsim ntawm cov raj square tuaj yeem cuam tshuam lub dav hlau siab. Piv txwv li, square tube kab uas siv nyob rau hauv lub tsev thav duab tuaj yeem ncaj qha welded rau lub dav hlau phab ntsa, txo kev siv cov khoom sib txuas thiab txhim kho tag nrho kev ruaj ntseg ntawm cov qauv.
- Chromium-molybdenum alloy steel kuj tau siv dav hauv tsheb, thiab nws muaj qhov hnyav txo qhov hnyav. Raws li tib lub zog, phab ntsa tuab ntawm chromium-molybdenum square tubes tuaj yeem thinned los ntawm ntau dua 30%, ncaj qha txo qhov hnyav ntawm lub cev tsheb, thiab tuaj yeem siv rau lub tsheb thav duab.
- Lwm qhov kom zoo dua ntawm Chromoly Steel yog nws qhov kub thiab txias tsis kam, uas tuaj yeem siv rau hauv qhov chaw kub siab heev, xws li kev tsim kho cov pa sib tw lossis cov khoom siv cav.
Daim ntawv thov ntawm ASTM A108 Chromoly Square Tube
ASTM A108 Chromoly Square Tubing pom daim ntawv thov nyob rau hauv ntau yam lag luam xws li tsheb, aerospace, kev tsim kho, thiab kev tsim khoom siv kis las. Nws yog feem ntau siv rau hauv kev tsim cov thav duab, yob tawb, cov khoom siv tsheb kauj vab, thiab lwm yam khoom siv uas yuav tsum tau muaj zog thiab rigidity.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm ASTM A108 Chromoly Square Tubing feem ntau suav nrog cov hauv qab no:

Cov qhab nia xaiv tau
- ASTM A519 (4130 / 4140) Txheem:- Seamless mechanical tubing nrog cov chemistry zoo sib xws
- ASTM A513 Hom 5- DOM tubing rau precision thiab du sab hauv
- TS EN 10297-1 (25CrMo4, 42CrMo4)- European sib npaug
- SAE 1026 lossis 1045- Cov kev xaiv qis dua rau cov ntawv thov tsawg dua
Ntim
Thaum cov kav dej tau dhau tag nrho cov kev tshuaj xyuas thiab kev sim, lawv npaj txhij rau ntim. Lawv feem ntau yog ntim rau hauv bales qhwv hauv yas. Cov kav dej tuaj yeem muab ntim thiab npaj rau kev xa khoom raws li cov neeg siv khoom xav tau, kom ntseeg tau tias cov kav dej muaj kev tiv thaiv thaum lub sijhawm thauj mus los thiab tiv thaiv qhov chaw puas.
