Product Description
ASTM A1085 is a high-performance structural steel tubing specification developed to provide improved strength, toughness, and consistency over traditional structural tubing specifications. Commonly used in building construction and structural applications, A1085 tubing is designed for superior performance in load-bearing and seismic environments. It is typically produced as electric resistance welded (ERW) tubing in square, rectangular, and round shapes.
Product Benefits
Higher minimum yield strength for improved structural efficiency. Enhanced dimensional tolerances for precision construction. Improved toughness and ductility. Better seismic performance. Reduced wall thickness variability. Consistent quality for demanding construction applications.
Product Advantages
Higher strength compared to ASTM A500, allowing for lighter designs. Tight dimensional tolerances reduce fabrication issues. Greater reliability in critical structural applications. Excellent weldability and fabrication performance. Ideal for seismic and dynamic load environments.
Specifications & Requirements
Manufactured to ASTM A1085 specification standards. Minimum yield strength of 50 ksi. Controlled wall thickness tolerances. Enhanced chemistry controls for carbon equivalent. Requirements for Charpy V-notch toughness testing in certain applications. Designed for structural applications requiring improved performance over A500.
Product Properties
High yield and tensile strength. Improved toughness and impact resistance. Excellent weldability. Uniform cross-section and wall thickness. Consistent mechanical properties throughout the material.
Product Wall Thickness Options
Available in a wide range of wall thicknesses with tighter tolerances than ASTM A500. Sizes and thickness depend on section shape and structural requirements.
Product Materials & Manufacturing
Manufactured from carbon steel. Produced using the electric resistance welding (ERW) process. Incorporates tighter process controls to meet enhanced ASTM A1085 requirements. May include additional fabrication services such as cutting, drilling, or coating.
Product Comparable Options
ASTM A500 structural tubing for general structural use. ASTM A53 pipe for basic applications. ASTM A106 seamless pipe for pressure applications. A1085 is preferred when higher performance and tighter tolerances are required.
Additional Notes
Commonly specified in commercial construction, bridges, and high-performance structural systems. Ideal for projects requiring improved seismic resistance and consistent material performance. Increasingly used as a replacement for ASTM A500 in critical applications.
