cov khoom siv thev naus laus zis
Dab tsi yog cov khoom ntawm S460NL cov khoom?
S460NL, tshwj xeeb, muaj aYam tsawg kawg nkaus yield zog ntawm 460 MPa ntawm 16mm tuab thiab hauv qab no, ua rau nws cov khoom siv ruaj khov thiab txhim khu kev qha rau kev siv cov qauv siv. Qhov kev faib tawm no tau hais txog qhov cuam tshuam tsawg kawg nkaus ntawm lub zog ntawm qhov kub tsis qis dua -50 deg C (NL).
S460NL steel phaj qibKhoom No. Yog 1.0490. S460NL steel yog ib yam ntawm normalized los yog normalized dov weldable zoo grain structural steels.S460NL steel phaj yog ib tug siab zog siv steel uas tau normalized thiab yog zoo heev rau tej lub sij hawm uas yuav tsum tau ib tug tawv muaj zog structural steel. Nws kuj tau txhim kho toughness ntawm qhov kub thiab txias.
S460 steel qib yog dab tsi?
EN 10025: 3 S460N steel yogib tug qauv qib ntawm steel uas yog siv nyob rau hauv ntau yam kev siv. Nws yog haum rau siv nyob rau hauv lub Cheebtsam uas yuav tsum tau welded raws li nws tau yooj yim koom los ntawm welding.
