Hawk Metals

India’s top Supplier/Stockist of SS and MS Bars

Stainless Steel (SS) and Mild Steel (MS) bars are essential components in various industries due to their distinct properties and applications. SS bars, made from high chromium steel alloys, offer exceptional corrosion resistance and durability, making them ideal for use in environments exposed to moisture, chemicals, and extreme temperatures. They are widely utilized in the food processing, marine, and chemical industries, as well as in construction and automotive sectors for their high strength and aesthetic appeal. On the other hand, MS bars, composed of low-carbon steel, are known for their ductility, malleability, and cost-effectiveness. Although MS bars are less resistant to corrosion compared to SS bars, they are extensively used in structural applications, manufacturing, and infrastructure development due to their versatility and ease of welding. Both SS and MS bars play crucial roles in construction, engineering, and manufacturing, serving as reliable materials for diverse applications.

Stainless Steel (SS) Round Bars: Complete Details

1. Stainless Steel (SS) Round Bars:

Material Composition: Stainless steel round bars are made of steel alloys with high chromium content (usually over 10.5%), which provides excellent corrosion resistance.

Grades:
Common grades include:
  • 304: Good for general use, high corrosion resistance.
  • 304L: Low carbon version of 304, good for welding applications.
  • 316: Contains molybdenum for enhanced corrosion resistance in harsh environments.
  • 316L: Low carbon version of 316, ideal for heavy welding.
  • 321 & 347: Enhanced resistance to intergranular corrosion.
  • 410 & 430: Ferritic stainless steels with moderate corrosion resistance.

    Types of SS Round Bars:
  • Hot Rolled Stainless Steel Round Bars: Manufactured at high temperatures, rough surface, suitable for structural use.
  • Cold Rolled Stainless Steel Round Bars: Smooth surface, high precision, used in applications requiring tight tolerances.
  • Bright Bars: Highly polished, precision bars used in decorative or mechanical applications.
  • Forged Bars: Strengthened through forging, used in heavy-duty applications like shafts and gears.

  • Sizes:
  • Diameter ranges from 4mm to 500mm.
  • Length typically between 3 to 6 meters, customizable.

  • Applications:
  • Marine equipment
  • Food processing machinery
  • Chemical processing
  • Architectural structures
  • Fasteners and shafts

  • Surface Finishes:
  • Hot Rolled Finish: Rough and mill-finished, commonly used in structural applications.
  • Bright Finish: Polished and smooth, for aesthetic and mechanical use.
  • Black Bars: Unpolished, used in industrial applications.
  • Mild Steel (MS) Round Bars: Complete Details

    Mild Steel (MS) Round Bars:

    Material Composition: Mild steel round bars are low-carbon steel with a carbon content of less than 0.25%, known for its ductility, malleability, and ease of welding.

    Grades:
    Common grades include:
  • IS 2062: Standard for structural steel.
  • EN8: Medium carbon steel with better strength than mild steel.
  • EN24: High tensile steel used for shafts and gears.

  • Types of MS Round Bars:
  • Hot Rolled Mild Steel Round Bars: Manufactured at elevated temperatures, used in structural applications.
  • Cold Drawn MS Round Bars: Processed at room temperature for precision applications.
  • TMT Bars: Thermo-mechanically treated bars with high strength and ductility, used in construction.

  • Sizes:
  • Diameter typically ranges from 6mm to 300mm.
  • Length varies from 6 meters to 12 meters, customizable based on application.

  • Applications:
  • Construction industry (beams, columns, etc.)
  • Manufacturing of machine parts
  • Automotive components
  • Industrial equipment and tools
  • Infrastructure projects

  • Surface Finishes:
  • Hot Rolled Finish: Rugged surface suitable for structural work.
  • Bright Finish: For decorative and mechanical uses.
  • Black Bars: Used in construction, infrastructure, and heavy machinery.
  • Key Differences between SS and MS Round Bars

    Corrosion Resistance: SS round bars are highly corrosion-resistant due to chromium content, while MS round bars require additional treatment (like galvanizing) to resist corrosion.

    Strength: SS round bars offer higher strength and durability, particularly in harsh environments. MS round bars are more economical but have lower corrosion resistance.

    Cost: SS round bars are more expensive due to the alloying elements, while MS round bars are cheaper and more widely used in structural applications.
