P91 Grade T91 Chromium-Moly Alloy Steel Plate from Japan
ASME SA387 Grade P91 (T91) is a 9Cr-1Mo-V alloy steel plate over 600 mm wide, used for power plant piping and superheaters. Its high chromium content (8% to 9.5%) is below the 10.5% threshold for stainless steel, so it is classified as other alloy steel. As a hot-rolled flat product not further worked, it falls under tariff item 7225.99.00 as 'Other'.
