ASTM A519, EN 10297-1


The ASTM A512 mechanical tubes are produced through a process called cold drawing, which involves pulling a solid tube through a die to reduce its diameter and improve its dimensional accuracy. This manufacturing method results in a smooth, uniform surface finish and tight tolerances.

These mechanical tubes are primarily used in applications where precise dimensions, excellent surface quality, and high strength are required. They find application in industries such as automotive, construction, machinery, and general engineering. Some common uses include shafts, bushings, cylinders, and other components subjected to mechanical stresses.

ASTM A512 specifies the chemical composition requirements, including carbon, manganese, phosphorus, sulfur, and other elements, to ensure the desired mechanical properties of the tubes. The standard also defines the mechanical properties such as tensile strength, yield strength, and elongation, which determine the tube’s ability to withstand external forces.

Overall, ASTM A512 mechanical tubes provide reliable performance and are manufactured to meet strict quality standards. They offer a durable and cost-effective solution for a wide range of mechanical applications requiring precision and strength.

The blanks used for welded steel pipes are steel plates or strip steel, which are divided into furnace welded pipes, electric welding (resistance welding) pipes and automatic arc welded pipes due to their different welding processes. Because of its different welding forms, it is divided into two types: straight seam welded pipe and spiral welded pipe. Because of its end shape, it is divided into round welded pipe and special-shaped (square, flat, etc.) welded pipe.
