Hauv cov txheej txheem steel engineering, cov khoom xaiv ncaj qha txiav txim siab txog kev nyab xeeb, ua haujlwm ntev, thiab lub neej voj voog tus nqi ntawm ib qhov project.
Ntawm GNEE Steel, peb tshwj xeeb hauv siab -kev ua tau zoo ntawm cov qauv steel, thiab pebS355J0 Channel Steeltau txais kev ntseeg siab los ntawm cov neeg cog lus thoob ntiaj teb rau sab nraum zoov thiab nruab nrab - daim ntawv thov kub qis.
S355J0 Channel Steel
Tab sis dab tsi ua rau qib "J0" tseem ceeb hauv kev xaiv cov hlau channel? Cia peb ua kom tawg.
S355J0 Channel Steel yog dab tsi?
S355J0 channel steel yog tsim raws li EN 10025-2, European structural steel qauv dav siv nyob rau hauv lub ntiaj teb no engineering tej yaam num.
S - Cov qauv hlau
355 - Tsawg tshaj tawm lub zog ntawm 355 MPa (tsawg dua lossis sib npaug li 16 hli thickness)
J0 - cuam tshuam toughness ntawm 27 Joules ntawm 0 degree
Piv nrog rau cov qib txheem xws li S355JR, S355J0 tshwj xeeb yog tsim los rau qis- qhov kub thiab txias ntawm cov qauv kev ntseeg tau, ua rau nws zoo tagnrho rau sab nraum zoov thiab txias- ib puag ncig raug.
S355J0 vs S355JR vs S355J2: Qhov txawv qhov tseem ceeb hauv Toughness
Rau cov ntawv thov channel steel, kev cuam tshuam kev ua haujlwm yog qhov tseem ceeb ntawm kev nyab xeeb. Cov hlau ua nkig ntau dua li qhov kub thiab txias, ua rau kev ntsuas qhov tseem ceeb.
| Qib | Impact Zog | Kev ntsuas kub | Daim Ntawv Thov Scope |
|---|---|---|---|
| S355 JR | 27J | +20 degree | Cov qauv hauv tsev, kev tsim khoom dav dav |
| S355J0 | 27J | 0 degree | Sab nraum zoov qauv, txuas hniav, infrastructure |
| S355J2 | 27J | -20 degree | Arctic, huab cua txias heev |
Vim li cas S355J0 tseem ceeb
S355J0 channel steel muaj qhov zoo sib npaug ntawm tus nqi thiab txias - huab cua kev ua haujlwm, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau feem ntau cov kev tsim kho thoob ntiaj teb kev ua haujlwm hauv huab cua nruab nrab.
Qhov zoo ntawm GNEE S355J0 Channel Steel
