Kev sib piv ntawm d6ac thiab d406a6AC steel

Kev sib piv ntawm d6ac thiab d406a

D6ac yog ib qho ultra-high-strength alloy structural steel, thiab d406a yog ib tug low-alloy ultra-high-strength steel. Ob leeg siv rau hauv aerospace khoom foob pob hluav taws, tab sis rau ntau lub hom phiaj.

D6ac yog qib tshwj xeeb steel siv los tsim cov khoom siv foob pob hluav taws. Nws yog ultra-high-strength alloy structural steel. d406a30 yog siv rau hauv cov hlau rau SiMnCrMoVE tshwj xeeb thiab cov cuab yeej tshwj xeeb uas muaj lub siab-resistant plhaub thiab cov qauv loj loj, nrog rau cov hlau muaj zog heev rau cov khoom siv foob pob hluav taws hauv aerospace.
Alloy structural steel yog hais txog cov hlau siv los ua cov khoom siv kho tshuab thiab ntau yam khoom siv engineering thiab muaj ib lossis ob peb yam ntawm cov ntsiab lus alloy.
