17-4 PH Precipitation Hardening Stainless Ingots
17-4 PH precipitation hardening stainless steel ingots, containing chromium and nickel with copper and niobium additions, are cast directly from vacuum induction melting. These primary forms are not further worked and are used as feedstock for aerospace components.
7218.10.00300 Series Stainless Steel Ingots
Large cast blocks of austenitic stainless steel alloys such as 304 or 316, produced by melting and pouring into molds. These ingots are primary forms of stainless steel, not yet hot-rolled into slabs or other semi-finished products.
7218.10.00304 Stainless Steel Billets
Cylindrical or square primary cast forms of grade 304 stainless steel, used as input for extrusion or forging. These billets are considered 'other primary forms' of stainless steel, not yet hot-rolled into usable shapes.
7218.10.00316L Stainless Steel Primary Ingots
Low-carbon 316L stainless steel ingots cast for corrosion-resistant applications in marine and chemical industries. These primary forms are unmachined and without surface treatment, falling under stainless steel ingots.
7218.10.00321 Stainless Steel Ingots
Titanium-stabilized 321 stainless steel ingots for high-temperature exhaust systems. These are primary cast forms, not clad or enameled, and are classified as stainless steel ingots.
7218.10.00409 Stainless Steel Billets for Exhaust Systems
Primary billets of 409 ferritic stainless steel used in automotive exhaust manufacturing. These billets are in primary form, before forging or rolling, and are classified as stainless steel primary forms.
7218.10.00430 Ferritic Stainless Steel Billets
Primary billets of 430-grade ferritic stainless steel with 16-18% chromium and no nickel, used for automotive trim. These billets are in primary form before rolling into sheets or bars.
7218.10.00Duplex 2205 Stainless Steel Primary Forms
Duplex 2205 stainless steel ingots or billets combining austenitic and ferritic phases for oil and gas piping. These are unwrought stainless primary products without further working.
7218.10.00High-Purity 304L Stainless Steel Primary Ingots
Ultra-low interstitial 304L stainless ingots for semiconductor and pharmaceutical equipment. These are pure primary forms, electroslag remelted for cleanliness, and are classified as stainless steel ingots.
7218.10.00Martensitic 410 Stainless Steel Ingots
Hardenable 410 martensitic stainless ingots with 12% chromium for pump shafts and valves. These are primary stainless castings, not further worked, and are classified as stainless steel ingots.
