Cov ntu hnyav rau S275J 0 Him Hlau Beams
Cov Qauv thiab Kev Tsim Qauv rau S275 H tws
S275: Yam tsawg kawg tau lees lub zog 275 MPa (tuab tsawg dua lossis sib npaug nrog 16 hli raws li {3}} 13.
J {{{{{0}}}}}: qhia tias qhov kev cuam tshuam nyuaj tau kuaj ntawm 0 degree nrog qhov tsawg kawg nkaus nqus lub zog ntawm 27J.
Ua raws li en 10025-2}: 2004 (cov qauv vaj ntxwv) thiab en 10034: 1993 (H-nqaj qhov ntev).
Hem series: European European Letric Steel Beams nrog dav flanges, ua kom zoo rau cov ntawv thov siab thauj khoom.
Yield lub zog (REH) ntawm S275 H Nqe Steel
Ntau dua los yog sib npaug rau 275 mpa (tuab tsawg dua lossis sib npaug rau 16 hli)
Ntau dua los yog sib npaug rau 265 MPa (16-40 hli)
Ntau dua los yog sib npaug rau 255 MPa (40-63 hli)
Tensile Lub Zog (RM): 410-580 MPA
Elongation (a): ntau dua los yog sib npaug rau 21% (elongation thaum tawg)
Kev cuam tshuam tawv: ntau dua los yog sib npaug rau 27 j ntawm 0 degree (charpy v-motch kuaj)
Cov Ntaw Ntaw Ntawm Hem Hnyav Profiles
Siab thauj khoom cov khoom muaj peev xwm: dav flanges thiab tuab webs kom ua kom zoo heev rau kev kub ntxhov thiab torsionional nyuab siab.
Tsawg-kub nyuaj: ductility thiab fracture kuj yog tswj hwm ntawm {{1} degree, haum rau huab cua txias. Weldability: tsawg cov pa roj carbon sib npaug (CEV tsawg dua lossis sib npaug ntawm 0. 43) tsawg kawg ntawm kev pheej hmoo ntawm kev tawg thaum lub sij hawm vuam.
Corrosion Kuj: tau tshaj nrog tiv thaiv tiv thaiv (piv txwv li galvanizing) rau siv nyob rau hauv ib puag ncig.
Cov ntawv thov ntawm S275 H-puab nqaj
Kev tsim kho hnyav: Txuas hniav hniav, high-nce tsev thiab kev txhawb nqa kev txhawb nqa thav ntawv.
Zog Infrastructure: Offshore platforms, cua Turbine yees thiab cov khoom siv tshuab hnyav.
Thauj: Kev tsheb ciav hlau thiab nkoj nkoj cov khoom siv uas yuav tsum muaj lub zog siab-rau-qhov hnyav.
