ASTM A131 EH36 steel plate shall be made to fine grain practice, and the requirements for fine austenitic grain size in Specification A6/A6M shall be met. After removal of any imperfection preparatory to welding the thickness of the plate at any location must not be reduced by more than 20 % of the nominal thickness of the plate.
ASTM A131 EH36 steel plate produced to a normalized heat treatment condition shall be marked with the suffix N to indicate that the plates have been normalized.
