AH32 Shipbuilding Steel ASTM A131 AH32 Marine Steel Plate/Coil

ASTM A131 AH32 steel Description

AH32 steel plate is a kind of marine steel plate. The "A" inside the grade indicates the quality grade of the steel plate, "H" indicates that the steel plate is a high-strength steel plate, and "32" simply and clearly indicates the yield strength of the steel plate. AH32 marine steel plate has good impact resistance and machinability, and corrosion resistance. AH32 ship plate can be used to manufacture hulls, ships and marine engineering, decks, etc. of oceangoing, coastal and inland waterway ships. AH32 marine steel plate implementation standard: It has passed the certification of nine countries' classification societies: CCS，ABS，GL，BV，DNV，NK，LR，KR，Rina, so the standards of nine countries' classification societies are implemented. The working environment of the ship is harsh, and the hull shell has to withstand the chemical corrosion of seawater, electrochemical corrosion, and the corrosion of marine organisms and microorganisms; it also has to withstand large wind and wave impacts and alternating loads; coupled with complex ship processing and molding, etc., so There are strict requirements on steel for hull structure.

ASTM A131 AH32 shipbuilding plate is high strength ship construction and offshore engineering structural steel. AH32 steel is equivalent to ABS AH32, BV AH32, CCS AH32, DNV AH32, GL AH32, NK AH32, LR AH32, KR AH32, RINA AH32, etc. Their main difference lies in certified by different classifications. AH32 shipbuilding steel plate is a structural steel for high-strength hull, and BBN Steel can produce steel for the hull structure according to the requirements of the classification society.

ASTM A131 AH32 steel Chemical composition

(heat analysis, % max unless otherwise specified)

Notes: 1) The contents of any other element intentionally added is to be determined and reported.

AH32 marine steel plates with 0.5 in. [12.5 mm] and under thickness may have a minimum Mn content of 0.70 %.
If the content of soluble aluminum is not less than 0.015 %, the minimum required silicon content does not apply.
Columbium and niobium are considered interchangeable names for the same element and both names are acceptable for use in A01 standards.
The indicated amount of aluminum, columbium (niobium), and vanadium applies if any such element is used singly.
Ca element need not be reported on the mill sheet unless intentionally added.
