A516 Gr 70 PVQ Carbon Steel Phaj
ASTM A516 boiler nkoj phaj yog sedated hlau, thiab yuav tsum tau raws li qhov yuav tsum tau ntawm ASTM A20 / A20M tus qauv zoo austenite grain loj. Lub thickness ntawm ASTM A516 boiler nkoj phaj tsuas yog txwv los ntawm lub peev xwm ntawm cov tshuaj muaj pes tsawg leeg kom ua tau raws li qhov yuav tsum tau ntawm cov khoom siv kho tshuab. Txawm li cas los xij, lub thickness ntawm Qib 55 phaj feem ntau txwv rau 305 hli. Lub thickness ntawm Qib 60, 65 thiab 70 daim hlau yog txwv rau 205 hli.
