IACS UR W11 Table 5 specifies normalized or thermo-mechanically rolled supply for E32 plates, subject to the producing mill and classification approval.
Normalized heat treatment (N) is a recognized delivery route for E32 hull plate under Table 5.
TMCP is a recognized E32 plate route when the mill process is approved and toughness criteria are met.
Through 50 mm and above 50 to 100 mm, use normalized or TMCP plate under the standard Table 5 plate route.
Specify any through-thickness testing, weld procedure or special project acceptance with the order.
