ASTM A500 Square Cold Formed and Seamless Carbon Structural Steel Pipe

ASTM A500 Cold -Formed Welded and Seamless Carbon Structural Tubing

Product Description:

This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes. This tubing shall be produced in both welded and seamless sizes and must have the chemical requirements of carbon, manganese, phosphorus, sulfur, and copper. The steel shall be produced by either open-hearth, basic-oxygen, or electric-furnace melting process. When steels of different grades are sequentially strand cast, the steel producer shall identify the resultant transition material and remove it using an established procedure that positively separates the grades. The tubing shall then be made by a seamless or welding process. Welded tubing shall be made from flat-rolled steel by the electric-resistance-welding process. The longitudinal butt joint of welded tubing shall be welded across its thickness in such a manner that the structural design strength of the tubing section is assured. Tension test and flattening test shall be conducted to the specimens. All tubing shall be inspected at the place of manufacture to ensure conformance to the requirements of this specification and must have a workmanlike finish that is free from defects.

Size Range:

	O.D(mm)	W.T.(mm)	L(mm)
Square tubes	5-420	0.5-50	max12000
Rectangle tubes	20-30 to 400-600	1-24	max12000

a. R_m: tensile strength ; R_eH: upper yield strength (but see 11.1); A: elongation. For symbols for the delivery condition see Table 1.
b. 1 Mpa = 1 N/mm²
c. Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strengths. For calculation purposes the following relations are recommended:
—— For delivery condition +C: R_eH ≥0.8 R_m
—— For delivery condition +LC: R_eH ≥0.7 R_m
d. For calculation purposes the following relations is recommended: R_eH ≥0.5 R_m
e. For tubes with outside diameter ≤ 30 mm and wall thickness≤ 3mm, the R_eH minimum values are 10 Mpa lower than the values given in this Table.

Applications:

for construction of bridges, and buildings, and for general strcutrual purposes,

For Algricultrual Michinery, Engineering etc.
