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.
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.
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.
AISI 4130 Chromoly Steel Sheet
> AISI 4130 is a chromium-molybdenum alloy steel supplied as flat-rolled sheet or plate over 600 mm wide. It is widely used in aerospace, racing, and structural applications due to its strength and weldability. It is classified as "other alloy steel" because it does not match the specific alloy steel definitions in Chapter 72.
AISI 4140 Alloy Steel Plate
> AISI 4140 is a chromium-molybdenum alloy steel plate with a width exceeding 600 mm, used in machinery, structural parts, and automotive components. It is a low-alloy steel that does not meet the definitions for stainless or other specialty steels, so it falls under "other alloy steel" flat-rolled products.
AISI 4340 Chromium-Molybdenum Steel Sheet
> AISI 4340 is a nickel-chromium-molybdenum alloy steel supplied as flat-rolled sheet or plate over 600 mm wide. It is used in aerospace and automotive components requiring high strength and toughness. It is classified as "other alloy steel" because it does not fit the definitions for stainless, electrical, or tool steels.
AISI 8630 Alloy Steel Mill Sheet
> AISI 8630 is a carburizing-grade alloy steel supplied as flat-rolled sheet over 600 mm wide, used for automotive transmission gears and other case-hardened parts. It contains nickel, chromium, and molybdenum, and does not meet specialty steel definitions, so it falls under "other alloy steel" flat-rolled products.
EN24 Alloy Steel Heavy Plate
> EN24 (40NiCrMo8) is a medium-carbon alloy steel plate with nickel, chromium, and molybdenum, flat-rolled and over 600 mm wide. It is used in heavy machinery bases and high-strength components. It is classified as "other alloy steel" because it does not match the definitions for stainless or other specific alloy steels.
HY-80 High-Yield Alloy Steel Plate
> HY-80 is a high-yield nickel-alloy steel plate over 600 mm wide, used in naval applications such as submarine hulls. It contains nickel, chromium, and molybdenum, and does not meet the definitions for stainless or other specialty steels, so it falls under "other alloy steel" flat-rolled products.
HY-80 High-Yield Submarine Hull Steel Plate
> HY-80 is a nickel-chromium-molybdenum alloy steel plate (width 800 mm) used for naval submarine hull construction, with a yield strength of 80 ksi. It is a high-strength alloy steel that does not meet the definitions for stainless or other specialty steels, so it falls under "other alloy steel" flat-rolled products.
SAE 8620 Case-Hardening Alloy Steel Plate
> SAE 8620 is a low-alloy steel plate with nickel, chromium, and molybdenum, flat-rolled and over 600 mm wide, used for carburizing applications in gears and shafts. It is classified as "other alloy steel" because it does not meet the definitions for stainless, electrical, or tool steels.
