JIS G 3466 - Tianjin Lefin Industrial Co., Ltd.

JIS G3466 tus qauv yog Japanese Industrial Standard uas qhia txog qhov yuav tsum tau rau carbon steel square thiab rectangular raj npaj rau lub hom phiaj dav dav. Cov raj no tau siv dav hauv kev tsim kho, engineering engineering, txuas hniav, tshuab, thiab ntau yam steel qauv. Lawv yog cov yam ntxwv los ntawm lawv cov weldability zoo heev, cov khoom siv kho tshuab tsis sib xws, thiab tus nqi -kev ua tau zoo rau cov qauv txheej txheem.

JIS G3466 tshwj xeeb npogcarbon steel tubes rau kev tsim qauvuas feem ntau yog tsim los ntawm txias- txheej txheem tsim thiab tom qab hluav taws xob tiv thaiv welded (ERW). Cov ntu no tau muab tso rau hauv raws li -rolled mob yam tsis muaj kev kho cua sov tshwj tsis yog tau teev tseg.

Cov qauv no qhia txog cov kev xav tau rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov ntev ntev ntawm cov qauv steel hlau.

Yog tias koj tab tom ua haujlwm nrog square lossis square hollow seem (SHS, RHS) rau cov qauv siv hauv cov haujlwm ua raws li cov lus qhia hauv Nyij Pooj lossis thoob ntiaj teb, kev nkag siab txog JIS G3466 yog qhov tseem ceeb los xyuas kom meej cov khoom zoo, kev tsim khoom sib xws, thiab kev ua haujlwm zoo.

JIS G 3466 Scope of Application:

JIS G 3466 qhia txog qhov yuav tsum tau ua rau cov pa roj carbon steel square thiab cov raj duab plaub uas tsim los ntawm cov txheej txheem hluav taws xob tiv thaiv vuam (ERW). Nws muaj feem xyuam rau cov raj siv rau kev tsim vaj tsev engineering, kev tsim kho, kev tsim vaj tsev, tshuab, thiab lwm yam kev siv hluav taws xob. Tus txheej txheem feem ntau npog cov pa roj carbon steel, kom ntseeg tau tias cov khoom siv kho tshuab txhim khu kev qha rau kev siv cov qauv.

Hauv cov ntsiab lus, JIS G3466 yog tus qauv rau cov qauv carbon steel hlau. Nws tshwj xeeb tsom rau cov qib carbon steel thiab nws lub hauv paus hauv Japanese Industrial Standards (JIS) system. Nws yog ib qho tseem ceeb heev rau kev siv xws li kev tsim vaj tse, txuas hniav, yees, thiab kev txhawb nqa.

Lub Classified Steels

Cov hlau hauv JIS G 3466 tau muab faib ua ntau qib raws li lawv lub zog tensile thiab cov ntsiab lus tawm los. Tsis zoo li European tus qauv uas siv cov ncauj lus kom ntxaws naming system nrog rau qhov ntsuas qhov cuam tshuam, JIS G 3466 siv cov txheej txheem tsim qib yooj yim.

Cov qib tseem ceeb tau teev tseg hauv JIS G 3466 yog:
