Lub cev muaj zog
Lub cev lub cev ntawm EN 10025 S355J2 pab txhawb rau nws cov kev siv tau hauv ntau qhov chaw:
Qhov ceev: 7.85 g / cm³, raug rau carbon steels, kom ntseeg tau tias qhov ntsuas qhov hnyav hauv kev tsim.
Thermal Conductivity: Kwv yees li 50 W / m·K ntawm chav tsev kub, haum rau cov cua sov hloov hauv cov khoom siv.
Coefficient ntawm Thermal Expansion: 11–13 × 10^-6 / K, tso cai rau kev ua haujlwm ruaj khov hauv qhov kub thiab txias.
Modulus ntawm Elasticity: 210 GPa, muab kev nruj rau kev thauj khoom -cov qauv kabmob.
Poisson's Ratio: 0.3, qhia txog tus cwj pwm elastic nyob rau hauv kev ntxhov siab.
Cov khoom no ua rau S355J2 ntau yam rau ob qho tib si zoo li qub thiab dynamic loads, nrog kev ua haujlwm zoo rau thermal expansion hauv kev tsim kho.
Corrosion Resistance thiab Durability
TS EN 10025 S355J2 muaj kev tiv thaiv corrosion tsis zoo nyob rau hauv tsis yog{3}} ib puag ncig nruj, txhim kho los ntawm silicon thiab tooj liab ntxiv uas ua rau muaj kev tiv thaiv patina hauv huab cua. Rau cov kab mob corrosive, nws tuaj yeem pleev xim lossis galvanized. Nws cov kav ntev yog pom tseeb nyob rau hauv nws qaug zog tsis kam thiab toughness, nrog ib tug qaug zog txwv nyob ib ncig ntawm 150-200 MPa rau cycles mus txog 10 ^ 7. Hauv kev siv qis- qhov kub thiab txias, nws qhov -20℃cuam tshuam lub zog tiv thaiv kev ua haujlwm tsis zoo, ua rau lub neej ua haujlwm hauv huab cua txias. Gangsteel muab clad los yog coated S355J2 daim hlau rau txhim khu kev ruaj khov nyob rau hauv ib puag ncig hnyav.
Sib piv nrog Lwm Cov Qib EN 10025
EN 10025 S355J2 yog ib feem ntawm tsev neeg S355, muab lub zog siab dua S275 qib tab sis zoo sib xws rau S355J0 (kuaj ntawm 0 degree) thiab S355K2 (40 J ntawm -20 degree). Cov lus hauv qab no piv S355J2 nrog rau lwm qib EN 10025-2:
