Nws muaj cov ntsiab lus carbon ntau ntawm 0.24% thiab feem ntau muaj ntau yam sib xyaw ntawm cov hlau, manganese, ntxaij, phosphorus, sulfur, thiab kab nqi ntawm lwm cov khoom.
- S3555j0: Hauv kev sib piv, S355J0 tsis muaj kev cuam tshuam tshwj xeeb tshwj xeeb rau hauv nws lub npe qib. Nws muaj cov ntsiab lus ntawm cov pa roj carbon ntau ntawm 0.22% thiab muaj cov ntsiab lus zoo sib xws rau S355jR, suav nrog cov hlau, pob zeb, siosphorus, sulfur, thiab cov kab ntxiv.
Cov Khoom Siv Neeg Kho Tshuab
- S3555jr: Cov qib no muaj tsawg kawg lub zog ntawm 355 megapSages (MPa) thiab lub zog yam tsawg kawg ntawm 470-630 MPa. Nws muaj cov weldability zoo, machinity, thiab muaj peev xwm.
- S3555j0: S355J0 kuj muaj tsawg kawg yog lub zog ntawm 355 MPa, tab sis nws qhov tsawg kawg nkaus tensile lub zog yog me ntsis qis dua, xws li 470-630 MPa. Zoo li S355jR, nws ua rau pom kev zoo weldability, machinity, thiab muaj peev xwm.
Kev siv thiab cov ntawv thov
S3555jr: Vim tias nws cov xwm txheej thiab kev cuam tshuam kev cuam tshuam, S355jr feem ntau yog siv rau hauv cov ntawv thov kev lag luam thiab qis}}}}}}}}}}}} {cov kab ntawv thov.
- S3555j0: Ntawm qhov tod tes, feem ntau siv nyob rau hauv siab dua- Lub zog articering cov ntawv thov thiab ntau dua xav tau ib puag ncig. Nws yog qhov tsim nyog rau tsim cov hnyav {{6} ntsaws}} bearing qauv qauv, cov choj, chaw teeb tsa sab nraud, thiab cov ntoo hluav taws xob.
Thaum ob qho tib si s355jr thiab s355j0 yog cov qauv txheej txheem nrog cov tshuaj sib thooj zoo sib xws, cov yuam sij tseem ceeb nyob hauv lawv cov kev cuam tshuam thiab kev siv cov xwm txheej. S3555j0 muaj cov khoom siv hluav taws xob me ntsis, ua kom haum rau cov ntawv thov uas xav tau lub zog siab dua. Nws yog qhov tseem ceeb los xav txog cov kev xav tau tshwj xeeb thiab tham txog cov qauv tsim tsim nyog lossis cov kws tshaj lij cov hlau tsim nyog rau ib daim ntawv thov.

Cov FAQ
Q: yog S355jR alloy steel?
A: Tshuaj, S355jr yog qhov qis-} carbon, tsis - allloy steel. Nws muaj pes tsawg leeg suav nrog cov ntsiab xws li manganese thiab silicon rau kev ua kom zoo nkauj tshuab kev ua haujlwm thiab ductility.
Q: Dab tsi yog qhov txawv ntawm S35JR thiab S275JR?
A: S275JR yog cov hlau hlau, thaum S355jr yog cov hlau tsis muaj roj. Ob leeg cov roj carbon steel s275jr thiab s355jr Tsawg Alloy Steel nyob hauv EN10025-2 txuj ci. S3555jr Tsawg Alloy Steel yog qib dua qib dua tshiab dua li cov roj carbon steel s275jr.
Q: Dab tsi yog qhov txawv ntawm S355JR thiab J2?
A: S355jr steel muaj qhov cuam tshuam tsawg kawg ntawm 27 J nyob rau hauv hom hlau, s355J {4} n muaj qhov kub ntawm lub zog tab sis nrog ib qho kub ntawm -20 degrees.
Q: Dab tsi yog s355jo steel?
A: Cov lus piav qhia. S355jo yog lub tensile nruab nrab, cov pa roj carbon manganese uas tau yooj yim weldable thiab muaj kev cuam tshuam zoo tsis kam. Cov ntaub ntawv no yog feem ntau muab tso rau hauv qhov tsis kho lossis cov xwm txheej qub. Tshuab ntawm cov khoom no zoo ib yam li cov hlau me me.
Q: Dab tsi yog ASTM sib npaug ntawm S355Jo?
A: ASTM A572 Qib 50
ASTM (Asmeskas Cov Qauv):
Q: Dab tsi yog qib S355 steel sib luag rau?
A: S355 sib npaug ntawm cov phaj
Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov neeg siv khoom hauv S355 yog tswj hwm los ntawm cov qauv yog li cas txawm li cas los xij, qee cov haujlwm yuav xav tau cov qauv uas ua tau cov qauv Astm. ASTM tau txheeb xyuas A572-50 raws li kev lees paub rau S355.
