Products Description

ASTM A131 hull structure steel AH32 shipbuilding plate with certificate

ASTM A131 hull structure steel AH32 shipbuilding plate is high strength ship and offshore engineering structural steel. The maximum thickness of AH32 shipbuilding plate under ASTM A131/A131M is 4in. [100mm]. BBN steel is marine grade shipbuilding steel products supplier and exporter. We can supply AH32 shipbuilding plate with certificates of ABS, LR, BV, DNV GL, RINA, NK, CCS, KR, or RMRS as your requirements. AH32 shipbuilding plate can do Z direction test: Z15, Z25, Z35.

ASTM A131 hull structure steel AH32 shipbuilding plate chemical composition:
(heat analysis, % max unless otherwise specified)

C Si Mn P S Al Min. Cb V Ti Cu Cr Ni Mo Ca N
0.18 0.10-0.50 0.90-1.60 0.035 0.035 0.015 0.02-0.05 0.05-0.10 0.02 0.35 0.20 0.40 0.08 0.005 -

Notes: 1) The contents of any other element intentinally added is to be determined and reported.
2) AH32 shipbuilding plate with 0.5 in. [12.5 mm] and under thickness may have a minimum Mn content of 0.70 %.
3) If the content of soluble aluminum is not less than 0.015 %, the minimum required silicon content does not apply.
4) Columbium and niobium are considered interchangeable names for the same element and both names are acceptable for use in A01 standards.
5) The indicated amount of aluminum, columbium (niobium), and vanadium applies if any such element is used singly.
6) Ca element need not be reported on the mill sheet unless intentionally added.
