AH32 Nkoj steel

Ah32 steel phajyog siv rau shipbuiling & platform.The shipbuilding steel phaj qib AH32 yog lub siab tensile zog steel. Ah32 shipbuilding steel muaj cov khoom zoo toughness, muaj zog dua, muaj zog corrosion-ua hauj, kev ua haujlwm, thiab vuam zog. ASTM A131 Ah32 steel phaj tuaj yeem siv rau hauv kev tsim khoom ntawm lub nkoj hull qauv uas nws qhov hnyav yog ntau tshaj 10000 tons.

Ah32 steel phaj Chemical Composition%

Qib	C max	Si max	Mn	P max	S max	Als min	Ti max	Cu max	Cr max	Ni max	Mo max
AW 32	0.18	0.50	0.90-1.60	0.035	0.035	0.015	0.02	0.35	0.20	0.40	0.08

Lus Cim: Feem ntau hais lus CE yuav yogTsawg dua los yog sib npaug0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.36% (thickness ≤ 50mm),≤0.38%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
