Khoom Qib & Standard
Ua ntejS355J2 steel phajRolling los ntawm steel specification EN 10025-2, thiabS355NL steel phajdov los ntawm steel specification EN 10025-3 kub dov structural steels nrog Normalized lossis Normalized dov kev xa khoom.
Qhov no txhais tau tias S355J2 tuaj yeem muab tau yam tsis muaj kev kho cua sov li qub, tab sis S355NL yuav tsum tau muab nrog kev kho cua sov lossis kev kho kom zoo.
Qhov txawv tseem ceeb
Nyob rau hauv qhov thib ob, S355J2 steel phaj yuav tsum tau ua charpy impacting test ntawm qis kub rho tawm 20 Degree Celsius, tab sis S355NL steel phaj yuav tsum tau ua qhov kev sim no nyob rau hauv qis kub rho tawm 50 Degree Celsius nrog tsawg kawg nkaus lub zog muaj nuj nqis 27J ntawm longitudinal.

FAQ
Q: S355NL yog dab tsi?
A: S355NL yog lub siab - lub zog muaj zog steel nrog zoo heev cuam tshuam toughness, tshwj xeeb tshaj yog nyob rau hauv qis - qhov kub thiab txias ib puag ncig. Nws yog siv rau hauv cov ntawv thov uas yuav tsum muaj lub zog thiab qis -kub toughness, xws li hauv kev tsim kho hnyav, kev tsim kho vaj tse, thiab cov qauv sab nrauv.
Q: Qhov txawv ntawm S355J2 thiab S355NL yog dab tsi?
A: S355J2: Requires preheating for thick sections (>30 mm). S355NL: weldability zoo dua vim cov nplej zoo thiab tsis muaj impurities; haum rau qhov tseem ceeb welds yam tsis muaj preheating. Xaiv S355J2 rau tus nqi- siv tau, dav dav- lub hom phiaj cov qauv hauv cov huab cua nruab nrab.
Q: S355J2 steel yog dab tsi?
A: S355J2 yog qhov nruab nrab tensile, qis carbon manganese hlau uas yog yooj yim weldable thiab muaj kev cuam tshuam zoo (tseem nyob rau hauv sub-zero kub). Cov khoom siv no feem ntau muab nkag rau hauv qhov tsis kho lossis tsis zoo. Machinability ntawm cov khoom no zoo ib yam li cov hlau me me.
Q: Qhov ntsuas kub li cas rau S355NL?
A: Tshem tawm 50 Degree Celsius
Nyob rau hauv qhov thib ob, S355J2 steel phaj yuav tsum tau ua charpy impacting test ntawm qis kub rho tawm 20 Degree Celsius, tab sis S355NL steel phaj yuav tsum tau ua qhov kev sim no nyob rau hauv qis kub rho tawm 50 Degree Celsius nrog tsawg kawg nkaus lub zog muaj nuj nqis 27J ntawm longitudinal.
Q: Qhov cuam tshuam ntawm S355NL yog dab tsi?
A: Cov yam ntxwv ntawm Qib S355NL: Qhov cuam tshuam rau kev nqus ua haujlwm yog ua nyob rau hauv qhov kub thiab txias ib puag ncig ntawm rho tawm 50 degrees, thiab qhov cuam tshuam tus nqi tsis tsawg dua 27J.
