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

 

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

ABS marine grade steel plates AH32 are mainly used to manufacture hull and deck of ocean, coastal and inland ships. ABS marine grade steel plates AH32 shipbuilding plate shall be normalized, control rolled, thermomechanical control processed, or quenched and tempered. The ABS marine grade steel plates AH32 with thickness more than 1/4 in. [6.4 mm] need Charpy V-notch test.
