Stainless Steel Bar

Stainless steel bars are solid, long cylindrical or rectangular bars made from stainless steel. They are available in various shapes, including round, square, flat, and hexagonal, to cater to different needs. Stainless steel bars are produced through hot or cold rolling processes, followed by annealing and pickling to enhance their properties.

Typical Chemistry:

The chemical composition of stainless steel bars varies depending on the grade. Common grades and their compositions include:

  • Austenitic Stainless Steels (e.g., 304, 316):

    • Iron (Fe): Balance
    • Chromium (Cr): 16-18% (304), 16-18% (316)
    • Nickel (Ni): 8-10.5% (304), 10-14% (316)
    • Manganese (Mn): Up to 2%
    • Silicon (Si): Up to 1%
    • Carbon (C): 0.08% max (304), 0.08% max (316)
    • Molybdenum (Mo) (in 316): 2-3%
  • Martensitic Stainless Steels (e.g., 410, 420):

    • Iron (Fe): Balance
    • Chromium (Cr): 12-14% (410), 12-14% (420)
    • Carbon (C): 0.15% max (410), 0.15% max (420)
    • Manganese (Mn): Up to 1%
    • Silicon (Si): Up to 1%
  • Duplex Stainless Steels (e.g., 2205):

    • Iron (Fe): Balance
    • Chromium (Cr): 22-23%
    • Nickel (Ni): 4.5-6.5%
    • Molybdenum (Mo): 3-3.5%
    • Manganese (Mn): Up to 2%
    • Silicon (Si): Up to 1%

Physical Properties:

The physical properties of stainless steel bars depend on the grade and processing. Typical properties include:

  • Density: Approximately 7.8 g/cm³
  • Tensile Strength:
    • Austenitic: 520-750 MPa
    • Martensitic: 600-750 MPa
    • Duplex: 620-880 MPa
  • Yield Strength:
    • Austenitic: 210-450 MPa
    • Martensitic: 240-400 MPa
    • Duplex: 450-600 MPa
  • Elongation:
    • Austenitic: 40-60%
    • Martensitic: 15-30%
    • Duplex: 20-30%
  • Hardness:
    • Varies by grade and condition (e.g., annealed, hardened)
  • Corrosion Resistance: Excellent, especially in austenitic and duplex grades
  • Thermal Conductivity: Lower than carbon steel
  • Magnetic Properties: Non-magnetic (austenitic), magnetic (martensitic and some duplex)

Features:

Key features of stainless steel bars include:

  • Corrosion Resistance: Exceptional resistance to rust and corrosion, making them ideal for harsh environments and corrosive media.
  • Strength and Durability: High tensile and yield strength provide excellent structural integrity, ensuring long service life.
  • Heat Resistance: Good performance at high temperatures, particularly in grades like 304, 316, and 410.
  • Workability: Excellent formability and machinability, allowing for complex shapes and structures.
  • Aesthetic Appeal: Attractive surface finishes available in various grades and textures.
  • Hygiene: Easy to clean and maintain, making them suitable for food, beverage, and medical applications.
  • Low Maintenance: Requires minimal upkeep due to its corrosion resistance and durability.
  • Versatility: Suitable for a wide range of applications, from industrial to decorative.
  • Recyclability: Environmentally friendly, as stainless steel can be fully recycled.
  • Magnetic Properties: Varies by grade, allowing for specific applications requiring magnetic or non-magnetic properties.
