A514 Grade B High-Yield Strength Alloy Steel Plate
> A514 Grade B is a quenched and tempered alloy steel plate over 600 mm wide, used for structural applications requiring high strength-to-weight ratio. It contains multiple alloying elements like chromium, molybdenum, and boron, making it an alloy steel. It does not match specialty steel definitions, so it is classified as "other alloy steel" flat-rolled products.

15CrMo Alloy Steel Pressure Vessel Sheet
> 15CrMo is a low-alloy steel containing chromium and molybdenum, supplied as flat-rolled sheet or plate over 600 mm wide. It is used in boilers and pressure vessels operating at elevated temperatures. It qualifies as "other alloy steel" because it does not meet the definitions for stainless, silicon-electrical, or high-speed steel.
A204 Grade C Molybdenum Alloy Steel Plate
> A204 Grade C is a molybdenum alloy steel plate for pressure vessels, with a width of 700 mm and thickness of 40 mm. It contains about 0.5% molybdenum, making it an alloy steel. It does not meet the definitions for stainless or other specialty steels, so it falls under "other alloy steel" flat-rolled products.
A302 Grade A Manganese-Molybdenum Alloy Steel Plate
> A302 Grade A is a manganese-molybdenum alloy steel plate over 600 mm wide, normalized for pressure vessel applications. It contains molybdenum (0.45-0.65%) and manganese, making it an alloy steel. It does not match specialty steel definitions, so it is classified as "other alloy steel" flat-rolled products.
A353 Grade Ni-Ni Alloy Steel Plate for Low-Temperature Service
> A353 is a 9% nickel alloy steel plate over 600 mm wide, used for cryogenic applications like LNG tanks. The high nickel content makes it an alloy steel, but it does not meet the definition of stainless steel (chromium <10.5%). It is classified as "other alloy steel" flat-rolled products.
A387 Grade 11 Heat-Resistant Alloy Steel Plate
> A387 Grade 11 is a chromium-molybdenum alloy steel plate over 600 mm wide, used in elevated-temperature service in refineries. It contains 1-1.5% chromium and molybdenum, making it an alloy steel. It does not meet the stainless steel definition (chromium <10.5%), so it falls under "other alloy steel" flat-rolled products.
A516 Grade 70 Pressure Vessel Steel Plate
> A516 Grade 70 is a carbon-manganese steel plate used for pressure vessels and boilers, with a width exceeding 600 mm. While it is primarily carbon steel, it may contain small amounts of alloying elements. It is classified as "other alloy steel" if it meets the alloy steel definition, otherwise it may be non-alloy. However, for this tariff item, it is considered alloy steel flat-rolled product.
