About Stainless Steel Bars & Heavy Plates
Heavy steel plates or stainless steel bars are used throughout many demanding industries that range from architecture and construction to industrial equipment, food processing, oil and gas, and much more. Throughout these industries, large-diameter steel is chosen for its ability to perform reliably under harsh conditions.
At Continental Steel, we provide large-diameter metals for the world’s most demanding applications, including aircraft-grade stainless steel for the military, stainless steel plates for oil drilling rigs, and many others. On this page, we will explain what stainless steel bars and heavy steel plates are and how our products are used.
Stainless Steel Bars
The term “large-diameter stainless steel bars” refers to bars that are up to 20 in. or 24 in. in diameter. At Continental Steel, we offer stainless steel bars in many grades, including 304/304L and 316/316L. All of these grades provide high strength, durability, and corrosion resistance, making them suitable for demanding environments or chemical exposure.
304/304L Grade Stainless Steel Bars
This grade of large-diameter stainless steel bars is composed of an austenitic stainless steel alloy containing 18% chromium and 8% nickel. They can be heat treated to improve their hardness or tensile strength, and they provide high ductility and excellent corrosion resistance. This grade of large-diameter stainless steel is commonly used in chemical processing, brewing, and food processing applications.
316/316L Grade Stainless Steel Bars
Commonly used in marine environments, medical equipment, and chemical processing, this grade of stainless steel is particularly resistant to corrosion in chloride-rich environments. They are easy to fabricate and feature a higher content of molybdenum which makes them more highly resistant to pitting and crevice corrosion.
Both of these grades can be produced using multiple methods, including hot rolling and cold drawing. Their large diameter makes them ideal for heavy-duty applications where strength and corrosion resistance are critical. At Continental Steel, we offer many grades of stainless steel, including:
- 15-5
- 17-4 PH
- 410/410 QDT
- 416
- Duplex 2205
- Duplex 2507
- Nitronic 50

Applications of Large Diameter Stainless Steel Bars
Due to their strength and durability, large-diameter stainless steel bars have a wide range of uses throughout numerous industries. The following are some of the most common applications in which our products are used.
- Manufacturing: Heavy machinery, equipment, and components production
- Construction: Reinforcing concrete structures, bridges, and buildings
- Chemical processing: Chemical tanks, pipelines, and valves that will be exposed to corrosive chemicals and high temperatures
- Marine: Shipbuilding, oil and gas extraction, offshore drilling
- Food processing: Conveyor belts, storage tanks, food processing equipment
Stainless Steel Plates
Stainless steel plates can be made from numerous metal grades that each deliver unique properties. They are all high-strength, durable, and corrosion-resistant. Stainless steel plates from Continental Steel are used throughout harsh applications that demand a long-lasting solution, including chemical processing, food processing, construction, and many others.
304/304L Stainless Steel Plates
Made from an austenitic stainless steel alloy, these plates contain 18% chromium and 8% nickel. For this reason, they provide excellent corrosion resistance and high ductility. For heavy-duty applications, they are available up to 6 inches thick. They are commonly used in brewing, chemical processing, and food processing.
316/316L Stainless Steel Plates
Also made from austenitic stainless steel alloy, but with a higher molybdenum content, this grade performs well in chloride-rich environments. These plates are frequently used in marine applications as well as chemical processing, and medical equipment.
2205 Stainless Steel Plates
Grade 2205 is a duplex stainless steel alloy containing austenitic and ferritic phases. It provides superior strength, toughness, and corrosion resistance, particularly in acidic environments. This grade of stainless steel plate is used in the pulp and paper industry, as well as chemical processing, oil and gas, and many others.
410 Stainless Steel Plates
Grade 410 stainless steel is a martensitic stainless steel alloy containing 11.5% chromium. This ensures its high strength, corrosion resistance, and hardness. It is commonly used in the oil and gas industry for pumps, valves, and drilling equipment production. We offer 410 stainless steel plates in thicknesses up to 4” for heavy-duty applications.
These are just a few examples of the many uses for thick stainless steel plates. Selecting the ideal grade for any given application will depend on factors such as the required level of corrosion resistance, desired mechanical properties, and environmental conditions.
