Frequently Asked Questions About 310 SS Round Bar

310 stainless steel round bars are widely used in high-temperature industrial applications due to their excellent oxidation resistance and mechanical strength. Common applications include furnace components, heat exchangers, chemical processing equipment, petrochemical plants, power generation units, aerospace parts, and food processing machinery.

310 SS rods can withstand continuous service temperatures up to 1150°C (2102°F) and intermittent service up to 1040°C (1904°F). The lower carbon variant, 310S, is suitable for slightly lower temperatures but offers better corrosion resistance in moist environments.

Yes, 310 stainless steel rods and 310S stainless steel rods have excellent weldability using standard procedures. They can also be machined and fabricated, though cold-rolled 310 rods may be less machinable than annealed rods.

The weight of a 310 stainless steel round bar can be calculated using the formula:
Weight (kg) = Diameter² × Length × 0.00785
This formula assumes the density of SS 310 as 7.85 g/cm³. Using this, you can estimate the weight for custom diameters and lengths.

310 stainless rods resist oxidation at high temperatures and exhibit excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. 310S rods offer enhanced resistance in moist or mildly corrosive environments, making them ideal for chemical and furnace applications.

310 stainless steel round bars are available in several finishes:

  • Hot Rolled – rougher surface, suitable for industrial applications
  • Cold Drawn/Polished – smooth, bright finish for aesthetic or precision applications
  • No. 2B finish – smooth, moderately reflective finish
  • Bright Annealed (BA) – reflective, mirror-like finish for decorative purposes

SS 310 round bars are typically available in diameters ranging from 4mm to 500mm. Hex and square bars usually range from 18mm to 57mm, with lengths from 1m to 6m. Custom cut lengths and diameters are also available based on client requirements.
