ASTM – 529

ASTMA529-50 Carbon-Manganese steel angle is widely used in structural applications. Not only it is more stronger than common A36 steel angle, but also its high-content of Manganese makes A529-50 very suitable for construction of bridges, high-rise steel buildings, rivet and bolt, as well as machinery and fabrication. Another different point compared with A36 is that A529-50 containing 0.2% content of copper which will resist weather and other kinds of corrosion.

Our A529-50 angle iron has equal or unequal.

 A529 steel angle description:

  • Steel grade: A529-50.
  • Specification: ASTM A529.
  • Technology: hot rolled.
  • Type: equal & unequal.
  • Equal angle:
    • Size: 20 × 20 mm – 200 × 200 mm.
    • Thickness: 3 to 22 mm.
    • Length: 6 m, 9 m, 12 m or as required.
  • Unequal angle:
    • Size: 20 × 30 mm to 90 × 250 mm.
    • Thickness: 3 to 15 mm.
    • Length: 6 m, 9 m, 12 m, or as required.
  • Note: Special angle steel sizes are available if your order quantity surpasses the minimum.

ASTM A529 steel angle features & benefits:

  • High-strength carbon steel angle with a minimum yield point of 50 ksi.
  • Stronger than common mild A36 angle.
  • Lower the overall weight owing to higher yield strength.
  • 2% copper content adding corrosion resistance.
  • Available for welding, riveting and bolting.
  • Popular as supporting components of buildings, bridges and other steel structures.

What is the difference between A36 & A529-50?

  1. Chemical Component: A529-50 has higher content of carbon & manganese which improves A529-50 yield point strength.
  2. Special addition of copper content makes A529-50 better corrosive-resistance than A36.
  3. For the same thickness, A529-50 is a lot stronger than A36, which allows for weight reduction.
