Khoom Description
JIS G3445 Carbon Steel Seamless Mechanical Tubing
Vim li cas JIS G3445 carbon steel seamless steel yeeb nkab muaj qhov zoo dua hauv kev siv tshuab?
1. Cov khoom siv steel yeeb nkab raws li tus qauv JIS G3445 feem ntau yog qis - carbon steel, xws li STKM11A/STKM13 series, nrog rau vuam carbon sib npaug (CE) ntawm<0.35%, which can be welded without preheating, which can significantly reduce the processing cost. Compared with the same grade of carbon steel pipe, the cost is about 25% lower than ASTM A106 (because the high-temperature performance testing cost is saved).
2. STKM12C yog cov khoom siv zoo tshaj plaws xaiv rau hydraulic kheej kheej. Kev kam rau siab ntawm JIS G3445 carbon steel seamless steel yeeb nkab yog tswj ntawm ± 0.15mm los ntawm cov txheej txheem kos duab txias, thaum ASTM A53 xav tau kev sib tsoo ntxiv nyob rau hauv tib lub tshuab ua haujlwm. JIS G3445 tau dhau los ua tus nqi -kev xaiv zoo rau Tsawg dua lossis sib npaug rau 32MPa hydraulic lub tog raj kheej lub cev nrog nws cov txheej txheem txias txias.
3. JIS G3445 carbon steel seamless yeeb nkab txhawb kev sib sib zog nqus ua haujlwm xws li stamping thiab dabtsi yog khoov, thiab tuaj yeem siv rau chassis brackets thiab lub cev thav duab ntawm lub tsheb.
Daim ntawv thov
JIS G3445 Carbon Steel Seamless Mechanical Tube yog tsim rau ntau yam kev siv thoob plaws ntau yam kev lag luam. Cov ntawv thov no suav nrog:

Cov qhab nia xaiv tau
Thaum JIS G3445 qhia txog ntau yam ntawm carbon steel seamless mechanical tubing, muaj lwm qib muaj nyob rau hauv lwm cov qauv thoob ntiaj teb. Qee qhov kev xaiv los txiav txim siab yog ASTM A519, DIN 2391, thiab BS 6323.
Nws yog ib qho tseem ceeb rau kev sab laj cov qauv tsim nyog thiab sib piv cov khoom siv thiab cov lus qhia tshwj xeeb thaum txiav txim siab lwm qib rau cov ntawv thov tshwj xeeb.
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.
