Stainless Steel Angle

Stainless steel angles are L-shaped, right-angled bars made from stainless steel. They are available in various sizes, thicknesses, and grades, and can have equal or unequal leg lengths. The angles are typically produced by hot rolling or cold forming processes, which impact their surface finish and mechanical properties.

Chemistry Typical:

The chemical composition of stainless steel angles depends on the grade. Common grades 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%
    • 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%

    • 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
