ASTM A179 Steel Pipe
ASTM A179 Steel Pipe
Discover the pinnacle of steel pipe technology with our ASTM A179 seamless cold-drawn low-carbon steel tubes. Designed meticulously for heat exchangers, condensers, and a myriad of heat transfer applications, our pipes ensure optimal performance even in the most demanding conditions. Beginning with a diameter as small as 1/8” (3.2mm) and extending up to 3” (76.2mm), our range is vast and versatile. While the ASTM A179 standard primarily covers these dimensions, we understand the unique needs of every project and offer sizes even beyond the specified range. Trust in our commitment to quality, precision, and durability as you embark on your next engineering marvel.
ASTM A179 Specification
Our ASTM A179 tubes are a testament to precision engineering. Manufactured through a seamless process, each tube undergoes rigorous cold drawing to ensure impeccable quality. The production process is complemented by comprehensive heat and product analyses, ensuring that the steel conforms to the stringent chemical compositions of carbon, manganese, phosphorus, and sulfur. Each tube is also subjected to a series of tests, including hardness, flattening, flaring, flange, and hydrostatic tests, guaranteeing not just compliance but excellence. Whether it’s surface coatings, end types, joint methods, or machining services, we offer a holistic solution tailored to your needs.

| Tubing smaller in outside diameter and having a thinner wall than indicated in this specification is available. Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in outside diameter or with a wall thickness under 0.015 in. [0.4 mm]. | |
Chemical Requirements of ASTM A179 Steel Pipe
Our ASTM A179 tubes are meticulously crafted to meet strict chemical requirements. The composition includes Carbon (C) at 0.06-0.18%, Manganese (Mn) at 0.27-0.63%, Phosphorus (P) at a maximum of 0.035%, and Sulfur (S) not exceeding 0.035%. In instances where the tube is supplied as an alloy grade, the above specifications may vary. Rest assured, our commitment to quality ensures that every tube meets or exceeds these chemical standards, offering you unparalleled performance and longevity.
| Chemical Composition | |
|---|---|
| Carbon, % | 0.06–0.18 |
| Manganese, % | 0.27–0.63 |
| Phosphorus, max, % | 0.035 |
| Sulfur, max, % | 0.035 |
Mechanical Requirements of ASTM A179 Steel Pipe
Beyond chemical composition, the mechanical properties of our ASTM A179 tubes are paramount. Each tube is subjected to a series of rigorous tests to ensure they meet the highest standards. From hardness tests that gauge the tube’s resistance to deformation, to flattening, flaring, and flange tests that assess its ductility and resilience, every aspect is scrutinized. Additionally, each tube undergoes a hydrostatic test or a substitute nondestructive electric test, ensuring its strength and integrity in real-world applications.
| Tensile Properties | |
|---|---|
| Tensile strength, min, ksi [MPa] | 47 [325] |
| Yield strength, min, ksi [MPa] | 26 [180] |
| Elongation in 2 in. or 50 mm, min, % | 35 |
Steel Grades in ASTM A179 Tube
Our ASTM A179 tubes are crafted from the finest grades of steel, ensuring durability, resilience, and performance. While the primary grade adheres to the chemical compositions specified, we also offer tubes in various alloy grades, tailored to specific applications and environments. Each grade is chosen for its unique properties, ensuring that you receive a product that’s perfectly suited to your needs. Trust in our expertise and experience as we guide you to the ideal steel grade for your project.
