ASTM A871 Grade 65 Corten Steel Plates & Sheet

ASTM A871 Grade 65 is a low alloy structural steel known for its high strength and improved resistance to atmospheric corrosion. This steel plate develops a protective layer, known as patina, on its surface, enhancing its durability. The ASTM A871 Grade 65 Corten Steel plate is also noted for its good weldability and machinability, making it suitable for critical outdoor applications.

ASTM A871 Grade 65

Applications

  • Strength: With a minimum yield strength of 65 ksi and a minimum tensile strength of 80 ksi, ASTM A871 Grade 65 is ideal for transmission poles.
  • Corrosion Resistance: It offers superior rust resistance compared to other carbon steel grades, even without additional copper in its composition.
  • Cost Efficiency: This steel can be used in its bare condition, eliminating the need for extra protective coatings and reducing costs.
  • Aesthetic Appeal: It forms a reddish-brown weathered appearance, making it visually appealing for various structural applications.

Benefits of ASTM A871 Grade 65 Steel 

  • Strength and Durability: ASTM A871 Grade 65 has excellent strength and corrosion resistance, ensuring long-lasting performance.
  • Cost-Effectiveness: Due to its high durability and extended service life, it offers a cost-effective solution for structural applications.
  • Aesthetic Versatility: The steel’s patina not only provides protection but also gives an attractive, natural look.
  • Versatile Applications: Available in different dimensions, it performs well in a wide range of weather conditions, making it versatile for various structural uses.

Tolerances

Mill Plate Tolerances:

  • Thickness, Width, and Length: These tolerances for ASTM A871 Grade 65 plates follow the ASTM A6 standard.
  • Flatness: Standard flatness tolerances as per ASTM A6 are available for all plate thicknesses.

Temper Leveled Plate Tolerances:

  • Thickness, Width, and Length: These tolerances adhere to the ASTM A6 standard.
  • Flatness: Half-standard flatness tolerances or better, in accordance with ASTM A6, are available. The flatness capability depends on the processing line and the material’s minimum yield strength.

Coil Conversion Tolerances:

  • For Minimum Gauge Orders:
    • Thickness: Adheres to ASTM A568 for thicknesses less than 0.230 inches and ASTM A635 for thicknesses from 0.230 inches to 1.00 inch. Specific tolerances are detailed in Table S1.1 of ASTM A635 and A568.
    • Width: Follows the guidelines in Table 6 of ASTM A568 and Table 3 of ASTM A635.
