1. Overview of ASTM A213 T5 Alloy Steel Tubing

ASTM A213 T5 is a chromium-molybdenum alloy steel grade designed for high-temperature and high-pressure service in boilers, superheaters, and heat exchangers. The addition of chromium and molybdenum significantly improves oxidation resistance, creep strength, and structural stability at elevated temperatures. Because of these properties, T5 tubes are widely used in power generation, petrochemical plants, refineries, and other demanding thermal environments.

At Womic Steel, ASTM A213 T5 tubes are manufactured under strict quality control systems and supplied in accordance with international standards. Our production complies with ASTM A213 / ASME SA213 requirements, and materials can be delivered with EN 10204 3.1 or 3.2 certification. For European pressure equipment projects, we also provide products compliant with the PED (Pressure Equipment Directive) 2014/68/EU with full traceability and inspection documentation.

With advanced manufacturing facilities and stable raw material supply channels, Womic Steel ensures reliable product quality, flexible customization, and efficient global delivery.

2. Product Specifications and Dimensional Range

ASTM A213 T5 tubes supplied by Womic Steel cover a wide range of diameters and wall thicknesses suitable for boiler tubing, heat exchangers, and pressure piping systems. Both seamless hot finished and cold drawn tubes are available depending on application requirements.
