Qhov txawv ntawm Q690D thiab S690QL1 yog dab tsi?

Q690D yog Suav teb tus qauv hlau, thaumS690 QL 1yog European txheem steel, nrog rau qhov sib txawv tseem ceeb yog lawv cov qauv sib npaug thiab qhov ntsuas kub. Ob leeg yog siab -lub zog, quenched thiab tempered structural steels nrog lub nominal yield zog ntawm 690 MPa, tab sis S690QL1 muaj ib tug qis dua Charpy tej yam ntsuas kub (−60∘𝐶) piv rau Q690D (−20∘𝐶).

S690QL1 yog lub siab -lub zog, quenched thiab tempered structural steel nrog zoo heev toughness, tsim nyob rau hauv lubTS EN 10025-6txheem. Txawm hais tias nws yog feem ntau muab raws li dov phaj, forging kuj tuaj yeem ua tau raws li kev tswj xyuas nruj nruj thiab cov neeg kho tshuab kom ua tau raws li lub zog sib xws thiab nplua -grain microstructure.
