Cov tshuaj muaj pes tsawg leeg ntawm Q460ND feem ntau suav nrog hlau, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel thiab lwm yam khoom. Ntawm lawv, carbon yog lub ntsiab tseem ceeb cuam tshuam rau lub zog thiab hardness ntawm hlau, silicon thiab manganese cov ntsiab lus tuaj yeem txhim kho lub zog thiab hardness ntawm hlau, thaum phosphorus thiab sulfur ntsiab tuaj yeem ua rau cov tawv tawv ntawm cov hlau. Alloying ntsiab xws li chromium thiab npib tsib xee, ntawm qhov tod tes, tuaj yeem txhim kho corrosion kuj ntawm hlau.
Cov khoom siv kho tshuab ntawm Q460ND feem ntau suav nrog lub zog tensile, yield zog, elongation thiab seem shrinkage thiab lwm yam ntsuas. Ntawm lawv, tensile lub zog yog ib qho tseem ceeb qhia kom muaj kev cuam tshuam lub zog ntawm steel, yield zog sawv cev rau lub siab tshaj plaws bearing peev xwm ntawm steel nyob rau hauv lub quab yuam. Elongation thiab seem shrinkage qhia txog cov khoom yas ntawm cov hlau.
Lub zog tensile ntawm Q460ND yog nyob ntawm 460-540 MPa thiab lub zog tawm los ntawm 345-420 MPa. Tsis tas li ntawd, Q460ND muaj kev cuam tshuam zoo toughness thiab qis-kub toughness, thiab muaj peev xwm tswj tau zoo heev mechanical zog ntawm qis kub.
Q460ND muaj qhov zoo vuam zoo thiab tuaj yeem welded siv ntau txoj kev vuam. Nws cov pob qij txha welded muaj lub zog zoo thiab tawv, thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm cov qauv. Tsis tas li ntawd, Q460ND kuj muaj qhov zoo weldability thiab tuaj yeem hloov kho raws li qhov yuav tsum tau muaj ntawm ntau yam txheej txheem vuam.
