Yuav ua li cas qhov tsawg - kub kev kub heev ntawm s355j0w piv rau S355K2W? -} kev paub

Qhov qis - kub tawv ntawm s355j0w thiab s355k2w sib txawv ntau, nrog qhov sib txawv tseem ceeb, nrog qhov sib txawv tseem ceeb hauv lawvYuav tsum muaj kev cuam tshuam rau qhov kubThiab tom ntej ua tau zoo hauv cov chaw txias Hauv qab no yog qhov tseeb, cov ntsiab lus sib piv:

1. Tub ntxhais sib txawv: Qhov yuav tsum muaj cov kev xav tau

Qhov kev qhia ncaj ncees tshaj plaws yog lawv qhov kev ntsuas cuam tshuam cuam tshuam, uas teeb tsa lub hauv paus rau lawv cov qes - kub ua tau zoo:

Kev qhia tshwj xeeb	S355J0W	S355K2W
Yuav tsum muaj kev cuam tshuam kub	0 Qib	-20 degree
Yam tsawg kawg nkaus cuam tshuam lub zog (KV2)	Ntau dua los yog sib luag rau 27 j (charpy v - next} tsis mus xeem)	Ntau dua los yog sib luag rau 27 j (charpy v - next} tsis mus xeem)
Kev ncaj ncees tsom	Lub ntsuas kub ib puag ncig (tsis muaj lub sijhawm khov khov kho)	Chaw txias hauv ib puag ncig (txhawb nqa sub - xoom} XOOM temperatures)

Qhov no txhais tau tias S355k2W tau zoo meej engineered kom ceev nrawm ntawm qhov kub 20 degree} Qhov sib txawv tseem ceeb rau cov chaw winters.

2. Kev ua tau zoo nyob rau hauv qhov kub thiab txias

Lawv tiag {- ntiaj teb tawv diving craveges tau kub siab 0 degree, cuam tshuam ncaj qha rau kev nyab xeeb thiab ruaj khov:

a. Saum toj 0℃(temperate tej yam kev mob)

Ob qho tib si ntawm ob qho zoo sib xws: lawv cov kev cuam tshuam txog kev cuam tshuam deb tshaj li 27 J rau S355J0W, 70-100 J rau S355K2W).

Tsis muaj kev sib txawv ntawm no -}}}}}}}}} resist resist resist brittle tsis ua tiav (piv txwv li, cua, kev ua phem).

b . 0℃rau -10℃(certizing me me mob)

S355J0W: Cov tawv me tshaj tawm sai heev. Ntawm - 5 degree, nws cov kev cuam tshuam hluav taws xob yuav poob mus rau 30-40 j (NW nyuam qhuav los sab saud 27 J yam tsawg kawg nkaus). Ntawm -10 degree, nws feem ntau ntog hauv qab 27 j, thawb cov hlau mus rau hauv thaj av "

S355K2W: Tawv tseem nyob ruaj khov. Ntawm -10 degree, nws cov kev cuam tshuam lub zog nyob nruab nrab ntawm 45-60 j (zoo dua qhov tsawg kawg nkaus), khaws cia. Tsis muaj kev phom sij microcacking, txawm tias muaj kev ntxhov siab me me.

c. Hauv qab -10℃(hnyav ua kom khov mob)

S355J0W: Ua tau nkig heev. Ntawm -15 degree, tej kev cuam tshuam lub zog plumbets rau<20 J-any sudden load (e.g., heavy snow, strong wind) can cause catastrophic brittle fracture, as the steel cannot absorb energy through plastic deformation.

S355K2W: Tseem ruaj khov kho tawv muaj zog. Ntawm - 20 degree, nws ua tau raws li 27 J yam tsawg (feem ntau sim ntawm 30-45 J), zam britle tsis ua tiav. Txawm tias ntawm -25℃(me ntsis hauv qab nws sim ntsuas kub), nws tseem tuaj yeem khaws ~ 25 J ntawm lub zog - txaus kom tiv thaiv me ntsis tsis muaj kev tawg.

3. Cov tswv yim cuam tshuam rau kev siv

Qhov kev nyuaj no nyuaj ncaj qha cuam tshuam rau cov hlau uas haum rau txias {{huab cua kev nyab xeeb txoj haujlwm:

Xaiv S355j0wtsuas yog rau thaj tsam nrogTsis muaj lub caij nyoog ntev tshaj - xoom} xoom(xws li, central Europe, Northern Is Nrias teb, qhov twg lub caij ntuj no qis tsawg tsawg dua 0 degree). Siv nws nyob rau hauv qhov chaw txias muaj kev phom sij thaum muaj microcacks.

Xaiv S355K2Wrau cov cheeb tsam nrogKev txhawb nqa kom khov txias(Xws li, Tebchaws Europe Sab Qaum Teb, Tebchaws Asmeskas, Canada, qhov twg Winters tsis tu ncua ntaus {}} 10℃rau -20 degree). Nws qhov qis-kub nyuaj ua kom muaj kev ncaj ncees kev ua kom ncaj ncees (tawg ua kom puas tsuaj rau kev tiv thaiv kev tiv thaiv corrosion).
