ASTM A500 is a standard specification for seamless and weldable carbon structural steel published by ASTM International. ASTM A500 rectangular pipe is a rectangular steel pipe that can be welded, riveted, or bolted for use in bridges or buildings and general structures.
Tensile Properties of ASTM A500 Rectangular Tubes
Notes
A: Suitable for steel pipes with wall thickness (t) ≥ 3.05mm. For thinner steel pipes, the minimum elongation can be calculated by the following formula: Secondary length per 50.8mm = 56t+17.5, rounded to two decimal places.
B: Suitable for steel pipes with wall thickness (t) ≥ 4.57mm. For thinner steel pipes, the minimum elongation can be calculated by the following formula: Elongation per 50.8mm = 61t+12, rounded to two decimal places.
C: Suitable for steel pipes with wall thickness (t) ≥ 3.05mm. For thinner tubes, the minimum secondary length can be agreed with the manufacturer.
D: The specified minimum elongation is only a reference value for test experiments, not a technical standard for steel pipe trade.
