IN WEIGHT %

Duracorr has low carbon content, up to 12.5% chromium, as well as the addition of molybdenum which stabilizes and ensures desired physicals for this product.

Physical Properties

Duracorr is strong, tough, corrosion resistant, formable and weldable. The physical characteristics of Duracorr make this material a prime candidate for numerous oil and gas applications involving pipe and plate.

Duracorr is available in grade 40 (40ksi yield), grade 50 (50ksi yield), and grade 300 (100-110 ksi yield.) Information below is based on Duracorr Grade 50.

  • Yield Strength:
  • 50 ksi minimum (345 MPa), 58 ksi typical (399 MPa)
    • Ultimate Tensile Strength:
  • 70 ksi minimum (483 MPa), 77 ksi typical (531 MPa)
    • Hardness:
  • 223 Brinnell maximum (97 Rb), 160 Brinnell typical (84 Rb)
    • Elongation (in 2 inches [50mm]):
  • 18 % minimum, 33 % average
    • Charpy-V-Notch Impact:
  • > 30 ft-lbs (41joules) at -40°F / -40°C. Duracorr exhibits excellent charpy values in the parent material, weld, and heat affected zone that all surpass the respective requirements in API, ASME and ASTM specifications.
