Yog tias koj tab tom xaiv cov khoom siv rau kev tsim qauv, kev nkag siab lub zog tseem ceeb ntawm S355W Corten steel yog qhov tseem ceeb. Qib no sib npaug huab cua tiv thaiv nrog kev txhim khu kev qha- cov kabmob muaj peev xwm.
Core Strength Specifications
Rau S355W weathering steel, qhov tsawg kawg nkaus yield zog thiab tensile zog yog txhais los ntawm European tus qauv EN 10025-5. Cov ntsiab lus tseem ceeb yog qhovQhov tsawg kawg nkaus tawm los lub zog sib txawv nyob ntawm seb lub thickness ntawm steel phaj.
Cov lus hauv qab no qhia txog yuav ua li cas lub zog tawm los (ReH) hloov nrog tuab, nrog rau qhov sib npaug tensile zog (Rm) ntau yam:
| Nominal Thickness (hli) | Yam tsawg kawg Yield Strength (ReH) | Tensile Strength (Rm) Ntau |
|---|---|---|
| Mus txog 16 | 355 MPa rau | |
| >16 rau 40 | 345 MPa rau | 470 - 630 MPa |
| >40 rau 63 | 335 MPa rau | |
| >63 rau 80 | 325 MPa | |
| >80 rau 100 | 315 MPa rau |
Vim li cas qhov no tseem ceeb rau koj tus qauv:
Yield zog (ReH)yog qhov kev ntxhov siab uas cov hlau pib deform mus tas li. Koj siv tus nqi no los xyuas kom meej tias koj cov qauv tswj nws cov duab hauv qab load. Qhov "355" hauv S355W txhais tau tias aYam tsawg kawg nkaus yield zog ntawm 355 MPa rau seem mus txog 16 hli tuab.
Tensile zog (Rm)yog qhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus thaum raug ncab. Qhov ntau ntawm 470-630 MPa qhia nws tag nrho lub zog thiab ductility.
Nkag siab lub npe "S355W".
Lub npe convention yog ib txoj cai ncaj qha rau nws cov khoom:
S: Stands rau "Structural" steel.
355: Qhia covQhov tsawg kawg nkaus tawm lub zog hauv MPa(rau thickness Tsawg dua los yog sib npaug rau 16mm).
W: Txhais tau hais tias "Weathering", txhais tau tias nws tsim ib qho kev tiv thaiv xeb patina.
Sib piv Cov Qib S355 Huab Cua Huab Cua
S355W yog ib feem ntawm tsev neeg. Cov tsiaj ntawv tom qab thiab cov lej (xws li J0, J2, K2) qhia qhov sib txawv toughness qib rau kev cuam tshuam, uas yog ib qho tseem ceeb rau qis -kev siv kub.
| Qib | Qhov tseem ceeb sib txawv ntawm S355W | Cov ntsiab lus ntawm Daim Ntawv Thov |
|---|---|---|
| S355J0W | Guaranteed cuam tshuam tsis kam ntawm0 degree. Ib qho, dav dav -lub hom phiaj huab cua steel. | Kev tsim kho dav dav, facades, thiab cov qauv hauv cov huab cua nruab nrab. |
| S355J2W | Guaranteed cuam tshuam tsis kam ntawm-20 degree. Muab qhov zoo dua qis -kub toughness. | Cov choj, cov qauv raug, lossis cov ntawv thov hauv thaj chaw txias dua. |
| S355K2W | Zoo ib yam li S355J2W tab sis nrog kev tsim khoom sib txawv rau kev lees paub toughness. | Heavy- cov qauv ua haujlwm uas tau teev tseg cov khoom muaj txiaj ntsig zoo. |
Xaiv Cov Qib Zoo rau Koj Qhov Haujlwm
Kev xaiv ntawm cov qhab nia no nyob ntawm koj qhov project ib puag ncig thiab cov kev xav tau:
Rau kev siv dav dav thiab zoo nkauj: S355J0Wfeem ntau yog tus qauv thiab yooj yim tshaj plaws xaiv rau cov tsev, sculptures, thiab cov thawv uas kub tsis tshua muaj kev txhawj xeeb.
Rau cov qauv tseem ceeb lossis huab cua txias: Yog tias koj qhov project yog tus choj, lub thauj khoom -cov kabmob thav duab hauv cheeb tsam nrog lub caij ntuj no txias, lossis ib qho kev nyab xeeb- cov qauv tseem ceeb, qhia meejS355J2Wlos yogS355K2Wmuab pov thawj toughness tiv thaiv brittle puas.
Nco ntsoov xyuas nrog daim ntawv pov thawj zeb: Rau cov qauv kev ncaj ncees, ib txwm xav tau cov khoom siv daim ntawv pov thawj zeb xeem. Cov ntaub ntawv no txheeb xyuas tias cov phaj xa tuaj raws li qhov xav tau ntawm cov khoom siv kho tshuab thiab tshuaj lom neeg rau koj qib uas tau teev tseg.
Hauv cov ntsiab lus, S355W Corten steel muab qhov tsawg kawg nkaus tawm lub zog pib ntawm 355 MPa thiab lub zog tensile ntawm 470-630 MPa. Los ntawm kev nkag siab cov nuances tom qab nws lub npe thiab cov qib sib xws xws li S355J2W, koj tuaj yeem ua qhov kev xaiv paub uas ua kom muaj kev ruaj ntseg thiab kev nyab xeeb rau koj daim ntawv thov tshwj xeeb.
