Khoom Description
S355J0WP steel phaj yog ib qho ntawm cov qib tseem ceeb ntawm qis- alloy, siab - lub zog huab cua cov qauv hlau. Nws belongs rau European EN tus qauv weathering steel system. Cov phaj hlau no muaj cov khoom zoo heev atmospheric corrosion resistance, mechanical zog, thiab workability, ua rau nws dav siv nyob rau hauv sab nraum zoov qauv, muaj khoom, thiab tej yaam num nyob rau hauv heev corrosive ib puag ncig.
Lub ntsiab lus tshwj xeeb ntawm kev xaiv qib yog:
- S:Cov qauv hlau, qhia nws qhov tseem ceeb siv rau kev thauj khoom -cov kabmob cov khoom siv.
- 355:Yield zog tus nqi (unit: MPa), qhia cov hlau qhov taw tes tawm ntawm chav tsev kub tsis pub tsawg tshaj 355 MPa.
- J0:Impact test grade, qhov "J" qhia txog qhov kev ntsuam xyuas hluav taws xob (V-notch), thiab "0" qhia qhov ntsuas qhov ntsuas kub yog 0 degree. Kev cuam tshuam lub zog Akv tsis tsawg dua 27 J. Qhov no ua kom muaj zog nyob rau hauv qis- qhov kub thiab txias ib puag ncig, tiv thaiv nkig tawg.
- WP:Weathering performance, specifically indicating that this steel grade incorporates alloying elements (copper, chromium, nickel, etc.) to form a dense, stable oxide rust layer in atmospheric environments, thereby significantly enhancing corrosion resistance.
Key Performance Indicators
| Yam khoom | Kev Xav Tau |
|---|---|
| Yield zog (ReH) | Ntau tshaj los yog sib npaug rau 355MPa rau thickness Tsawg dua los yog sib npaug rau 16mm; Ntau dua lossis sib npaug ntawm 345MPa rau thickness 16-40mm; Ntau dua los yog sib npaug rau 335MPa rau thickness 40-63mm (tso me ntsis nrog nce thickness) |
| Tensile zog (Rm) | 470-630MPa (sib npaug zog thiab ductility rau kev yooj yim ua thiab sib sau) |
| Elongation (A) | Ntau dua lossis sib npaug li 21% (ua kom zoo ductility ntawm cov hlau kom ua tau raws li kev xav tau xws li khoov thiab vuam) |
| Impact Zog (Akv) | Ntau dua lossis sib npaug ntawm 27J ntawm 0℃(tsim rau qhov chaw kub thiab txias; rau qis- huab cua tsis kam, J2 qib tau pom zoo nrog Akv Ntau dua lossis sib npaug rau 27J ntawm -20 degree) |
| Corrosion Resistance | Atmospheric corrosion tus nqi yog 1/3-1/5 ntawm cov pa roj carbon zoo tib yam (kev ua tau zoo hauv kev lag luam, huab cua hauv hiav txwv, thiab chaw nyob deb nroog) |
| Kev Xa Khoom | Feem ntau kub- dov (AR), tswj- dov (CR) lossis normalized (N); Kev kho cua sov txheej txheem tuaj yeem kho raws li qhov xav tau |

Yuav Ua Li Cas Xaiv Qhov Zoo Huab Cua Hlau
Environmental Matching:Rau qhov kub thiab txias sab nraum zoov ib puag ncig, ua ntej qib J0 (0℃cuam tshuam tsis kam). Rau qhov txias lossis qis- qhov kub thiab txias (hauv qab -20 degree), hloov mus rau S355J2WP (-20℃cuam tshuam).
Thickness xaiv:Txiav txim siab thickness raws li load- bearing xam kom tsis txhob nce ntxiv.
Standard Confirmation:Rau kev lag luam thoob ntiaj teb, qhia meej meej rau EN 10025-5 txhawm rau tiv thaiv kev tsis sib haum xeeb nrog cov qib sib npaug los ntawm lwm lub tebchaws (xws li Tuam Tshoj Q355NH muaj cov ntsiab lus nickel sib txawv).
Kev yuav tsum tau ua:Rau txoj kev khoov los yog stamping txoj haujlwm, xaiv tswj tau -rolled (CR) tus me nyuam tus mob rau superior plasticity.
