Q690D yog lub siab - lub zog qis {}}}}} lub zog txheem qauv. Nws yog renowned rau nws ultra {{5 5 5} Lub zog muaj zog, ua rau nws cov ntaub ntawv zoo tshaj plaws rau kev siv hnyav thiab cov ntawv thov. Hauv qab no yog cov ncauj lus qhia ntxaws los ntawm cov yam ntxwv tseem ceeb, tshuaj lom neeg, cov khoom siv mechanies, los thov cov teb:

Cov yam ntxwv tseem ceeb

Ultra - lub zog siab: Nrog rau tsawg kawg los lub zog ntawm 690 MPa, nws nyob deb tshaj qhov ntawm cov qauv txheej txheem zoo tib yam (xws li QU235)

Zoo qes - kub nruj: Tus "D" nyob rau hauv qib qhia tias nws poob qis {{degree} kev cuam tshuam kub (AKV) ntawm 34 J, ua kom muaj kev cuam tshuam tsawg kawg nkaus hauv lub zog.

Zoo heev Weldability: Vim tias nws cov roj carbon qis (feem ntau tsawg dua lossis sib npaug nrog 0.50%), nws tuaj yeem muab welding sib tw) tsis muaj qhov tseem ceeb preheating thiab tus nqi.

Cov Khoom Ruaj Ntseg Ruaj Ntseg: Nruj kev tswj cov khoom siv (suav nrog smelting, dov, thiab kev kho cua sov) kom cov kev ua tau zoo thoob plaws ntawm lub phaj ntawm cov pob.

Cov Kev Tsim Nyog Zoo: Nws tuaj yeem ua tiav los ntawm kev khoov, stamping, thiab txiav, sib ntsib cov duab uas yuav tsum muaj ntawm cov txheej txheem ua haujlwm nyuaj.

 

 

 

 

 

 

 

 

 

 

Tshuaj lom neeg tshuaj lom neeg (raug,% los ntawm huab hwm coj)

Cov pa roj carbon (c): tsawg dua lossis sib npaug zos rau 0.18 - Cov ntsiab lus muaj cov pa roj carbon tsawg kom muaj kev thaiv kom muaj weldability thiab tawv.

Silicon (Si): tsawg dua los yog sib npaug rau 0.60 - txhim kho lub zog thiab deoxidation.

Manganese (MN): 1.00-1.60 - Kom muaj kev nyuaj siab thiab tsis muaj zog.

Phosphorus (p): tsawg dua lossis sib npaug rau 0.030 - nruj me ntsis tswj kom tsis txhob brittleness.

Sulphur (s): tsawg dua los yog sib npaug rau 0.020 - txo qhov kev pheej hmoo ntawm cov kev pheej hmoo ntawm kub tawg thaum vuam.

Chromium (CR): 0.40-0.70 - txhim kho cov kev nyuaj thiab xeb tsis kam.

Nickel (NI): 0.50 - 1.00 - txhim kho cov khoom kub qis thiab lub zog.

Molybdenum (mo): 0.10 {- 0.30 - txhim kho siab dua qhov kev ruaj khov thiab qhov ruaj khov.

Niobium (NB) / titanium (ti) / v) (tag nrho cov qauv muaj zog, tag nrho txhim kho lub zog thiab tawv ntxiv los ntawm kev ua kom zoo.
