Dab tsi yog qhov kev ua tau zoo ntawm Q690D high-strength steel phaj?
Q690D high-strength steel phaj yog txias-kuav los tiag steel phaj uas nws lub ntsiab Cheebtsam yog carbon, silicon, manganese, phosphorus, sulfur, chromium, npib tsib xee, molybdenum thiab lwm yam khoom.Piv nrog rau cov hlau zoo tib yam, Q690D steel phaj siab muaj cov yam ntxwv hauv qab no.
(Kom kawm paub ntxiv txog qhov cuam tshuam ntawm cov khoom steel tshwj xeeb, xws lisiab zog low alloy steel, koj tuaj yeem tiv tauj peb)
1. Lub zog muaj zog
Lub zog tawm los ntawm Q690D siab-lub zog steel phaj yog 690MPa, uas yog ntau dua li cov hlau phaj zoo tib yam.Lub phaj siab muaj zog steel phaj no yog tsim rau tej yaam num uas dais loj loads thiab high-strength yuav tsum tau, xws li txuas hniav thiab cov tsev.
2. Zoo toughness
Q690D high-strength steel phaj muaj qhov toughness zoo thiab tuaj yeem tiv taus qhov hnyav thiab hnyav loads.Cov phaj hlau no yog tsim rau cov haujlwm uas yuav tsum tau tiv thaiv cov khoom loj, xws li nkoj thiab tsheb.
