- Vanadium cov ntsiab lus ntau: Tsawg dua lossis sib npaug rau 0.12 feem pua

 

Lub zog tensile ntawm S275NL yog 430-580 MPa, lub zog tawm los yog 275 MPa, thiab qhov elongation ntawm tawg yog 22 feem pua. Qhov no txhais tau hais tias nws muaj zog nruab nrab thiab siab toughness yam ntxwv.

 

S275NL normalized structural steel yog haum rau ntau lub teb, xws li tshuab, tsev, nkoj, thiab petrochemical khoom. Hauv cov teb no, cov hlau uas muaj lub zog nruab nrab thiab siab tawv yuav tsum tau ua kom ntseeg tau cov qauv thiab kev nyab xeeb.

 

Normalization yog txheej txheem kev kho cua sov ntawm cov hlau mus rau qhov ntsuas kub kom tsim nyog thiab tom qab ntawd txias nws sai. Kev kho kom zoo tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau thaum tuav cov weldability zoo thiab toughness. Qhov no ua rau S275NL normalized structural steel haum rau kev ntxhov siab nyob rau hauv kev kub siab thiab kub ib puag ncig.

 

Qhov zoo ntawm S275NL normalized structural steel muaj xws li:

- Lub zog nruab nrab: Nws muaj qhov nruab nrab ntawm lub zog tsim nyog rau ntau yam kev siv engineering.

- High toughness: Toughness yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv kev puas tsuaj. S275NL normalized structural steel muaj siab toughness.

- Weldability: Cov hlau no yooj yim rau vuam thiab tuaj yeem welded nrog ntau yam sib txawv vuam txheej txheem.

- Processability: S275NL normalized structural steel yog ib qho yooj yim rau cov duab thiab txheej txheem.

 

Qhov tsis zoo ntawm S275NL normalized structural steel muaj xws li:

- Tus nqi siab: Vim nws lub zog nruab nrab thiab cov tshuaj lom neeg tshwj xeeb, cov nqi tsim khoom kuj tseem siab.

- Hydrogen embrittlement: Nyob rau hauv cov txheej txheem kho cua sov, cov khoom raug cuam tshuam rau absorbing hydrogen, ua rau nkig tawg.

 

Cov ntaub ntawv ntawm S275NL normalized structural steel muaj xws li steel phaj, steel kav, I-beams, thiab steel tuav. Cov ntaub ntawv hlau no tuaj yeem muaj ntau haiv neeg thiab kho raws li qhov project tshwj xeeb lossis cov khoom yuav tsum tau ua.

 

S275NL normalized structural steel muaj qee cov qib sib piv hauv ntau lub teb chaws, xws li:

- Suav tus qauv: Q275Z

- American txuj: ASTM A36

- Nyiv tus qauv: SS540

 

Zuag qhia tag nrho, S275NL normalized structural steel yog cov hlau uas muaj zog nruab nrab thiab siab tawv haum rau ntau yam kev siv engineering scenarios. Txawm hais tias nws qhov tsis zoo, nws qhov zoo ntawm toughness thiab weldability ua rau nws tseem siv dav hauv ntau qhov chaw.
