A387 Grade 11 Heat-Resistant Alloy Steel Plate from China
ASTM A387 Grade 11 is a chromium-molybdenum alloy steel plate with a width exceeding 600 mm, used for elevated-temperature service in refinery and pressure vessel applications. Its chromium content of 1% to 1.5% by weight qualifies it as other alloy steel, but it does not meet the 10.5% chromium threshold for stainless steel. The product is hot-rolled and not further worked, placing it under tariff item 7225.99.00 as 'Other' flat-rolled alloy steel.
