Understanding the importance of accurate dimensions, our ASTM A210 tubes are available in a wide range of sizes. Typically, the tubing sizes furnished range from 1/2 in. to 5 in. in outside diameter and 0.035 to 0.500 in. in minimum wall thickness. However, we can also provide tubes with other dimensions, ensuring they comply with all other requirements of the ASTM A210 specification. With UNIACERO, you can be assured of precision in every inch.

Outside Diameter:1⁄2 to 5 in. [12.7 to 127 mm]
Wall Thickness:0.035 to 0.500 in. [0.9 to 12.7 mm]
Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.

Chemical Requirements of ASTM A210

Ensuring the longevity and reliability of our tubes, the chemical composition of our ASTM A210 tubes strictly adheres to the industry standards. We guarantee that no elemental composition other than those listed in the ASTM A210 standard is present. This rigorous adherence to chemical requirements ensures that our tubes are of the highest quality, offering resistance to corrosion, high temperatures, and wear.

Mechanical Requirements of ASTM A210

Mechanical integrity is paramount. Our ASTM A210 tubes undergo a series of mechanical tests, including tension tests, flattening tests, flaring tests, hardness tests, and hydrostatic or nondestructive electric tests. These tests ensure that our tubes can withstand the mechanical stresses they will face in their applications, guaranteeing a long service life and optimal performance.

Steel Grades in ASTM A210

We offer ASTM A210 tubes in two primary steel grades: Grade A1 and Grade C. Each grade is designed to cater to different applications and environments. Grade A1 is known for its superior tensile strength, while Grade C offers enhanced resistance to high temperatures. Both grades are crafted to ensure they meet the rigorous demands of heat exchange appliances and power engineering applications.
