Lub zog tensile ntawm S355N yog 470-630 MPa, yield zog yog 355 MPa, thiab elongation ntawm so yog 22 feem pua. Qhov no txhais tau tias nws muaj zog nruab nrab thiab siab toughness.

 

S355N normalized structural steel yog haum rau ntau qhov chaw xws li lub tsev, txuas hniav, nkoj, machining thiab petrochemical industries. Hauv cov teb no, cov khoom siv hlau uas muaj lub zog nruab nrab thiab siab tawv yuav tsum tau ua kom ntseeg tau cov qauv thiab kev nyab xeeb ntawm cov khoom.

 

Normalization kev kho mob yog txheej txheem ntawm cua sov cov hlau mus rau qhov tsim nyog kub thiab ces txias nws sai sai. Kev kho kom zoo tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau, thaum tuav zoo weldability thiab toughness. Qhov no ua rau S355N normalized structural steel ntau ruaj thaum cuam tshuam nrog ntau qhov kev ntxhov siab thiab thermal deformation.

 

Qhov zoo ntawm S355N normalized structural steel muaj xws li:

- Lub zog nruab nrab: Nws muaj lub zog nruab nrab, haum rau ntau yam kev siv engineering.

- Zoo toughness: Toughness yog hais txog lub peev xwm ntawm cov ntaub ntawv los tiv thaiv puas, thiab S355N normalized structural steel muaj siab toughness.

- Zoo weldability: Cov khoom siv hlau no yooj yim rau vuam thiab tuaj yeem welded siv ntau yam txheej txheem vuam sib txawv.

- Kev ua tau zoo: S355N normalized structural steel tuaj yeem tsim thiab ua tiav los ntawm ntau txoj kev ua.

 

Qhov tsis zoo ntawm S355N normalized structural steel muaj xws li:

- Tus nqi sib npaug: Cov nqi tsim khoom kuj tseem siab vim muaj lub zog nruab nrab thiab xav tau cov tshuaj lom neeg tshwj xeeb.

- Tsawg solubility: Nyob rau hauv cov txheej txheem cua sov, intergranular embrittlement yuav tshwm sim, ua rau txo cov toughness ntawm cov hlau.

 

Cov ntaub ntawv ntawm S355N normalized structural steel muaj xws li steel phaj, steel kav, zoo li tus hlau thiab steel cov ntaub ntawv, thiab lwm yam. Cov ntaub ntawv hlau no tuaj yeem hloov kho thiab ua tiav raws li qhov yuav tsum tau ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov haujlwm lossis cov khoom siv.

 

S355N normalized structural steel muaj cov qib sib piv sib txawv hauv ntau lub teb chaws. Piv txwv li:

- Suav tus qauv: Q345E

- Asmeskas tus qauv: ASTM A572 Qib 50

- Japanese tus qauv: SM490

 

Hauv kev xaus, S355N normalized structural steel yog cov khoom siv hlau nrog lub zog nruab nrab thiab siab tawv, uas muaj ntau yam kev siv thiab kev ua haujlwm zoo. Nws yog dav siv nyob rau hauv kev tsim kho, txuas hniav, nkoj thiab lwm yam teb los dais nruab nrab loads thiab thermal deformation. Txawm hais tias muaj qee qhov tsis zoo, nws lub zog thiab qhov zoo ntawm qhov zoo ua rau nws tseem siv dav hauv ntau qhov chaw.
