300 Series Production Stainless Steel Bar 304, 304L, 321, 316L, 317L, 309s Alloy Stainless Steel Round Rods

Our 300 Series production stainless steel bars are a remarkable range of products designed to meet the most demanding industrial and commercial needs. Available in grades such as 304, 304L, 321, 316L, 317L, and 309s, these stainless steel round rods offer exceptional performance and versatility.

The 300 Series is known for its austenitic structure, which provides excellent corrosion resistance, high strength, and good formability. These bars are suitable for a wide variety of applications, including construction, automotive, aerospace, food processing, and chemical industries.

The surface treatment of our 300 Series stainless steel bars is complete, ensuring a smooth and uniform finish. This not only enhances the aesthetic appeal of the bars but also provides additional protection against corrosion and wear. The smooth surface also makes the bars easier to clean and maintain, which is crucial in applications where hygiene is a concern.

We use a combination of hot rolling and cold rolling techniques to produce these stainless steel bars. Hot rolling is used to shape the bars into the desired round shape and to improve their mechanical properties. Cold rolling, on the other hand, is used to further refine the surface finish and to increase the strength and hardness of the bars. The combination of these two techniques results in bars that have excellent dimensional accuracy, surface quality, and mechanical properties.

The bars are round in shape, which is a common and versatile shape for many applications. The round shape provides uniform stress distribution, making the bars suitable for use in structural applications where strength and stability are important. It also allows for easy machining and fabrication, which is beneficial for customizing the bars to meet specific project requirements.

• 304: This is the most widely used grade in the 300 Series. It has good corrosion resistance in a variety of environments and is suitable for general-purpose applications. 304 stainless steel is commonly used in kitchen equipment, architectural applications, and automotive parts.

• 304L: The "L" in 304L stands for low carbon. This grade has a lower carbon content than 304, which makes it more resistant to intergranular corrosion. It is often used in applications where welding is required, as it reduces the risk of corrosion in the heat-affected zone.

• 321: This grade contains titanium, which stabilizes the steel and prevents the formation of chromium carbide during welding. It has excellent resistance to intergranular corrosion and is commonly used in high-temperature applications, such as exhaust systems and heat exchangers.

• 316L: Similar to 304L, 316L has a low carbon content. It also contains molybdenum, which enhances its corrosion resistance, especially in chloride-rich environments. 316L is widely used in marine applications, chemical processing, and medical equipment.

• 317L: This grade has a higher molybdenum content than 316L, which provides even better corrosion resistance in harsh environments. It is suitable for use in applications where exposure to strong acids and high temperatures is expected, such as in the chemical and petrochemical industries.

• 309s: This grade has a high chromium and nickel content, which gives it excellent oxidation resistance at high temperatures. It is commonly used in furnace parts, heat treatment equipment, and other high-temperature applications.

Our 300 Series stainless steel bars comply with a variety of international standards, including ASTM, AISI, GB, JIS, DIN, and EN. This ensures that the bars meet the highest quality and performance requirements and can be used in global markets. Compliance with these standards also provides our customers with the confidence that the products they are purchasing are reliable and safe for use in their applications.
