Mechanical Properties of S355JR H-section Steel
| Khoom | Tus nqi / Specification | Sau ntawv |
|---|---|---|
| Yield zog (ReH) | 355 MPa rau | Yam tsawg kawg nkaus tus nqi raws li EN 10025-2 |
| Tensile zog (Rm) | 470-630 MPa | Ua kom muaj peev xwm thauj khoom txaus |
| Impact Zog (Charpy V-notch, 20 degree) | Ntau dua lossis sib npaug li 27 J | Guarantees toughness nyob rau hauv ib txwm kub |
| Elongation (A) | Ntau dua lossis sib npaug li 20% | Qhia tau zoo ductility thiab deformation muaj peev xwm |
| Qhov ntom | 7.85 g / cm³ | Standard steel density rau xam qhov hnyav |
| Hardness (Brinell, approx.) | 140–180 HB | Reflects kuj rau nto indentation |
| Weldability | Zoo heev | Tau tshaj cov txheej txheem welding |
S355JR H seem steel nthuav qhia kev ua haujlwm zoo heev. Nws lub zog siab tso cai rau nws tiv taus qhov hnyav thiab hnyav. Txawm hais tias siv nyob rau hauv lub moj khaum ntawm loj - cov tsev loj los yog kev txhawb nqa hauv cov qauv choj, S355JR H-section steel muab kev ua haujlwm ruaj khov thiab txhim khu kev qha.
Nws zoo heev toughness xyuas kom meej tias cov hlau yog resistant rau tawg nyob rau hauv complex kev nyuaj siab tej yam kev mob, zoo heev txhim khu kev ruaj ntseg ntawm cov qauv. Qhov tshwj xeeb sib xyaw ua ke ntawm cov khoom no ua rau S355JR H-section steel qhov kev ntseeg siab rau cov kws ua haujlwm hauv kev tsim kho kev lag luam.

S355JR H profile hauv peb qhov project
S355JR H-beam profile tuav txoj haujlwm tsis tuaj yeem hloov pauv hauv kev tsim kho vaj tsev. Hauv ntau peb lub Hoobkas, S355JR H- kab teeb ua haujlwm yog cov kab teeb ci tseem ceeb, muab kev txhawb nqa ruaj khov thiab ruaj khov rau tag nrho cov qauv.
Lawv cov ntoo khaub lig tsis tu ncua -sectional shape kuj pab txhawb kev sib txuas thiab kev koom ua ke nrog lwm cov khoom siv, ua kom muaj kev tsim kho sai thiab ua tau zoo ntawm cov loj - nplai, ntev- ncua kev lag luam qhov chaw nrog siab load- cov kabmob muaj peev xwm.
Tsis tas li ntawd, rau qee qhov ntawm peb cov haujlwm siab - nce kev lag luam hauv tsev, kev siv S355JR H- kab teeb tsa txhim kho tag nrho kev ruaj ntseg thiab seismic kev ua tau zoo ntawm lub tsev, kom ntseeg tau tias cov qauv tseem muaj kev nyab xeeb thiab ruaj ntseg txawm tias muaj cua daj cua dub thiab av qeeg.
S355JR hlau steel beam feem ntau yog siv rau hauv peb cov khoom siv choj. Nws xyuas kom meej tias tus choj tswj kev ruaj ntseg nyob rau hauv kev nce tsheb thauj mus los, tiv thaiv deformation lossis hloov chaw thiab yog li txo qis kev phom sij ntawm tsheb. Tib lub sijhawm, qhov tshwj xeeb H- zoo li tus qauv tsim ntawm cov kab hlau steel ntxiv qhov tshwj xeeb zoo nkauj rau tus choj.
Peb muab S355JR H beams nrog nruj tolerances, xyuas kom meej txhua beam raws li nruj me ntsis qhov tseeb rau txhim khu kev qha kev ua tau zoo.
Raws li S355JR steel beam tsum, peb muab txhua qhov ntau thiab tsawg hauv Tshuag. Tiv tauj peb hnub no rau ib daim ntawv tso cai pub dawb thiab xyuas kom meej tias koj qhov project yog tsim los ntawm cov hlau koj tuaj yeem ntseeg tau.

Puas yog S355 sib npaug rau A36?
S355JR thiab A36 tsis sib npaug ncaj qha, raws li S355JR muaj lub zog ntau dua (yield 355 MPa vs. A36's 250 MPa) thiab lav qhov cuam tshuam toughness, ua kom ze rau ASTM A572 Qib 50 dua A36. A36 feem ntau sib npaug rau S235JR (yield 235 MPa), qis dua EN qib.
Dab tsi yog Asmeskas sib npaug ntawm S355 steel?
ASTM tau txheeb xyuas A572-50 raws li kev hloov pauv tau rau S355. Ob qib muaj cov tshuaj lom neeg zoo sib xws thiab muaj siab -lub zog, cov hlau tsis tshua muaj hlau.
S355 puas tuaj yeem hardened?
S355 tsis yog qhov zoo tshaj plaws rau kev ua kom tawv tawv, txawm hais tias nws tuaj yeem raug rau cov txheej txheem kev kho cua sov tsawg xws li cov ntaub ntawv hardening.
Dab tsi yog qhov txawv ntawm ASTM A572 thiab S355?
Daim ntaub ntawv: ASTM A572 Qib 50 feem ntau yog siv rau hauv cov ntawv siv hnyav dua uas xav tau lub zog ntau dua, thaum S355JR muaj ntau yam thiab siv dav hauv ntau yam kev siv hauv cov teb chaws Europe.
