Kev kho cua sov ntawm ASTM A556 Carbon Steel cev
- Cov raj txias txias yuav tsum tau kho cua sov tom qab qhov kawg txias-draw dhau ntawm qhov kub ntawm 1200 degree F [640 degree] los yog siab dua kom ntseeg tau tias cov khoom txaus siab rau dov rau hauv cov ntawv raj thiab ua kom tau raws li cov khoom siv raws li tau teev tseg.
- Yog hais tias kev ntxhov siab-relief anneal ntawm U-khoov tau teev tseg, lub anneal yuav tsum muaj cua sov ntawm qhov khoov ntawm qhov ntau ntawm 1100 txog 1200 degree F [585 txog 640 degree].
Mechanical Tests Yuav tsum muaj ASTM A556 Carbon Steel Tube
- Kev Ntsuas Siab
