Nta:
1.Tsawg carbon steel tubingnrog seamlessyog carbon steel nrog cov ntsiab lus carbon tsawg dua 0.25%. Nws tseem hu ua me me hlau vim nws tsis tshua muaj zog, tsis tshua muaj hardness thiab softness.
2. Cov qauv annealed ntawm qis carbon steel tubing nrog seamless yog ferrite thiab ib tug me me ntawm pearlite, uas tsis muaj zog thiab hardness, thiab zoo plasticity thiab toughness.
3. Tsawg carbon steel tubing nrog seamless muaj qhov txias formability thiab tuaj yeem txias tsim los ntawm crimping, dabtsi yog khoov, stamping, thiab lwm yam.
4. Tsawg carbon steel tubing nrog seamless muaj zoo weldability. Ib qho yooj yim mus txais ntau yam kev ua xws li forging, vuam thiab txiav.

Kev kho cua sov:
Tsawg carbon steel tubing nrog seamless muaj ib qho kev nyiam loj rau kev laus, ob qho tib si quenching thiab aging tendencies, nrog rau deformation thiab aging tendencies. Thaum cov hlau txias los ntawm qhov kub siab, cov pa roj carbon thiab nitrogen hauv cov ferrite yog supersaturated, thiab cov pa roj carbon thiab nitrogen hauv cov hlau tuaj yeem maj mam tsim ntawm qhov kub thiab txias, kom lub zog thiab hardness ntawm cov hlau zoo tuaj, thiab cov ductility. thiab toughness yog qis dua. Qhov tshwm sim no hu ua quenching aging. Tsawg carbon steel tubing nrog seamless yuav muaj cov nyhuv laus txawm tias nws tsis quenched. Lub deformation ntawm qis carbon steel tubing nrog seamless tsim ib tug loj tus naj npawb ntawm dislocations. Cov pa roj carbon thiab nitrogen atoms hauv ferrite cuam tshuam elastically nrog dislocations, thiab carbon thiab nitrogen atoms sib sau ua ke nyob ib ncig ntawm cov kab dislocation. Qhov kev sib xyaw ua ke ntawm carbon thiab nitrogen atoms thiab cov kab dislocation yog hu ua Cochrane gas mass (Kelly gas mass). Nws tsub kom lub zog thiab hardness ntawm hlau thiab txo cov ductility thiab toughness. Qhov tshwm sim no hu ua deformation aging. Deformation aging yog teeb meem ntau dua rau cov ductility thiab toughness ntawm tsawg carbon steel tshaj quenching aging. Muaj cov ntsiab lus pom tseeb sab sauv thiab qis qis ntawm qhov tensile nkhaus ntawm cov pa roj carbon tsawg. Los ntawm qhov taw tes rau sab sauv mus txog rau thaum xaus ntawm qhov kev nthuav tawm, ib qho chaw wrinkle tsim nyob rau saum npoo ntawm cov qauv vim tsis sib xws deformation yog hu ua Rydes siv. Muaj ntau qhov chaw stamping feem ntau yog muab pov tseg. Muaj ob txoj hauv kev los tiv thaiv nws. Ib txoj kev ua ntej deformation siab, cov hlau ua ntej deformed tau muab tso rau ib lub sijhawm thiab Rudes siv kuj tsim thaum stamping, yog li cov hlau pre-deformed yuav tsum tsis txhob muab tso rau ntev dhau ua ntej stamping. Lwm qhov yog ntxiv aluminium lossis titanium rau cov hlau los tsim cov khoom ruaj khov nrog nitrogen los tiv thaiv kev laus deformation los ntawm kev tsim ntawm Kodak huab cua huab cua.
