Applications and Uses of ASTM A656 Grade 60 in Industry

ASTM A656 Grade 60 is widely used in various applications, including:

  1. Truck frames
  2. Crane booms
  3. Rail car components
  4. Construction equipment
  5. Heavy vehicle frames
  6. Agricultural equipment
  7. Transport trailers

Manufacturing Process and Available Dimensions

ASTM A656 Grade 60 is typically produced through controlled rolling or thermo-mechanical controlled processing, which enhances its mechanical properties.Available Dimensions:

Thickness Range (inches/mm) Width Range (inches/mm) Length Range (inches/mm)
0.1875 – 1.50 / 4.78 – 38.1 72 – 120 / 1800 – 3050 Up to 240 / Up to 6100

Welding and Fabrication Considerations for Grade 60 Steel

ASTM A656 Grade 60 can be welded using standard welding techniques, including:

  • Welding Methods: Suitable for common fusion welding methods.
  • Filler Metals: Should match or exceed the strength of the base metal.
  • Preheating: Recommended to prevent cracking, especially for thicker sections.

Comparison of ASTM A656 Grade 60 with Other Grades

When compared to other grades within the ASTM A656 specification, such as Grades 50, 70, and 80, Grade 60 has higher yield and tensile strengths than Grade 50 but lower than Grades 70 and 80.

Grade Yield Strength (ksi) Tensile Strength (ksi)
A656 Grade 50 ≥50 ≥60
A656 Grade 60 ≥60 ≥70
A656 Grade 70 ≥70 ≥80
A656 Grade 80 ≥80 ≥90

Cost-Effectiveness and Performance Benefits

While ASTM A656 Grade 60 may have a higher initial cost compared to standard structural steels, its high strength-to-weight ratio allows for thinner sections, leading to potential savings in material costs, transportation, and installation.
