Tsawg alloy steel zog

(1) Lub zog siab: Feem ntau, nws lub zog tawm los yog siab dua 300MPa;
(2) High toughness: yuav tsum tau ib tug elongation tus nqi ntawm 15% mus rau 20%, thiab chav tsev kub tej yam toughness ntau tshaj 600kJ / m rau 800kJ / m. Rau loj welded Cheebtsam, siab tawg toughness kuj yuav tsum tau;
(3) Kev ua haujlwm vuam zoo thiab kev ua haujlwm txias txias;
(4) Tsawg txias brittle hloov kub;
(5) Zoo corrosion kuj.
