ASTM A511 Stainless Steel Mechanical Tubing for Precision Applications
ASTM A511 is the standard specification for seamless and welded mechanical tubing made from austenitic, ferritic, and duplex stainless steels. Unlike ASTM A269 or A312, which are used for pressure applications, A511 tubes are designed specifically for mechanical use-such as in hydraulic systems, aerospace structures, medical instruments, and precision-engineered components.
Advantages
GNEE offers high-quality austenitic stainless steel seamless tubes compliant with ASTM A511 standards, covering popular grades such as 304 (UNS S30400) and 316 (UNS S31600). These tubes provide excellent resistance to atmospheric corrosion, with tensile strength ≥ 515 MPa and yield strength ≥ 205 MPa, and are compatible with ER308/ER316 welding wires. They are well-suited for applications in general mechanical components, food processing pipelines, and light industrial fluid transport systems.
In addition, GNEE's ASTM A511 precision stainless steel tubing supports a range of value-added services, including:
Custom length cutting (tolerance ±3 mm)
Surface polishing (Ra ≤ 0.8 μm)
Solution annealing (1050–1100°C, water quenched)
100% hydrostatic testing
All materials comply with ASTM A511 / ASME standards, and are supplied with EN 10204 3.1 mill test certificates.
