Understanding UNS S34709 Bars
Before delving into the sizes, let's briefly understand what makes UNS S34709 special. This grade contains niobium, which stabilizes the alloy against intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range. It is often used in high-temperature applications, such as furnace components, heat exchangers, and power generation equipment.

Available Sizes of UNS S34709 Bars
We offer UNS S34709 bars in a variety of sizes to meet the diverse needs of our customers. The sizes are classified into diameters for round bars and dimensions for flat, square, and hexagonal bars.
Round Bars
Round bars are one of the most common forms of UNS S34709 bars. They are widely used in applications where a circular cross-section is required, such as shafts, fasteners, and pump components. Our round bars are available in diameters ranging from 6 mm to 250 mm.
- Small Diameters (6 mm - 20 mm): These smaller sizes are often used in precision engineering applications, such as the production of screws, bolts, and small shafts. The high strength and corrosion resistance of UNS S34709 make it suitable for these critical components.
- Medium Diameters (20 mm - 100 mm): Medium-sized round bars are used in a wide range of applications, including machinery parts, automotive components, and structural elements. They provide a good balance between strength and workability.
- Large Diameters (100 mm - 250 mm): Large-diameter round bars are typically used in heavy-duty applications, such as in the construction of industrial equipment, bridges, and large machinery. These bars require high-quality raw materials and precise manufacturing processes to ensure their structural integrity.
Flat Bars
Flat bars are rectangular in cross-section and are used in applications where a flat surface is required, such as in the construction of frames, brackets, and platforms. Our UNS S34709 flat bars are available in a thickness ranging from 3 mm to 100 mm and a width ranging from 20 mm to 300 mm.
- Thin Flat Bars (3 mm - 10 mm): These thin flat bars are often used in applications where weight reduction is important, such as in the aerospace and automotive industries. They can also be used for decorative purposes due to their smooth surface finish.
- Medium-Thick Flat Bars (10 mm - 50 mm): Medium-thick flat bars are commonly used in structural applications, such as in the construction of buildings and bridges. They provide good strength and stability while maintaining a reasonable weight.
- Thick Flat Bars (50 mm - 100 mm): Thick flat bars are used in heavy-duty applications, such as in the manufacturing of large machinery and industrial equipment. They are capable of withstanding high loads and stresses.
Square Bars
Square bars have a square cross-section and are used in applications where a uniform cross-section is required, such as in the construction of frames, support structures, and tooling. Our UNS S34709 square bars are available in sizes ranging from 10 mm x 10 mm to 150 mm x 150 mm.
- Small Square Bars (10 mm x 10 mm - 30 mm x 30 mm): These small square bars are often used in precision engineering applications, such as in the production of small components and fixtures.
- Medium Square Bars (30 mm x 30 mm - 100 mm x 100 mm): Medium-sized square bars are used in a variety of applications, including structural elements, machinery parts, and automotive components.
- Large Square Bars (100 mm x 100 mm - 150 mm x 150 mm): Large square bars are typically used in heavy-duty applications, such as in the construction of large industrial structures and equipment.
Hexagonal Bars
Hexagonal bars have a hexagonal cross-section and are used in applications where a specific shape is required, such as in the production of nuts, bolts, and other fasteners. Our UNS S34709 hexagonal bars are available in sizes ranging from 10 mm to 80 mm across the flats.
- Small Hexagonal Bars (10 mm - 20 mm): These small hexagonal bars are often used in precision engineering applications, such as in the production of small fasteners and components.
- Medium Hexagonal Bars (20 mm - 50 mm): Medium-sized hexagonal bars are used in a variety of applications, including machinery parts, automotive components, and structural elements.
- Large Hexagonal Bars (50 mm - 80 mm): Large hexagonal bars are typically used in heavy-duty applications, such as in the manufacturing of large fasteners and structural components.
Applications of UNS S34709 Bars
The wide range of sizes and excellent properties of UNS S34709 bars make them suitable for a variety of applications. Here are some of the common applications:
- High-Temperature Applications: UNS S34709 bars are widely used in high-temperature applications, such as in furnaces, heat exchangers, and power generation equipment. Their high resistance to oxidation and corrosion at elevated temperatures makes them an ideal choice for these applications.
- Chemical Processing Industry: The corrosion resistance of UNS S34709 makes it suitable for use in the chemical processing industry, where it can be used in the construction of reactors, piping systems, and storage tanks.

Comparison with Other Stainless Steel Grades
When choosing the right stainless steel grade for your application, it's important to compare UNS S34709 with other commonly used grades. Two popular grades that are often compared with UNS S34709 are Stainless Steel 317 / UNS S31700 / 1.4449 and Stainless Steel 321 / UNS S32100 / 1.4541.
- Stainless Steel 317 / UNS S31700 / 1.4449: This grade has a higher molybdenum content than UNS S34709, which gives it better resistance to pitting and crevice corrosion in chloride environments. However, UNS S34709 has better high-temperature properties and is more suitable for applications where high-temperature strength and oxidation resistance are required.
- Stainless Steel 321 / UNS S32100 / 1.4541: This grade is stabilized with titanium, which provides good resistance to intergranular corrosion. While it has similar corrosion resistance to UNS S34709, UNS S34709 has better high-temperature strength and is more suitable for high-temperature applications.
