Wuxi, China — With the increasing demand for durable and high-temperature-resistant materials in the energy and petrochemical sectors, Wuxi Sylaith Special Steel Co., Ltd. has announced the availability of its latest range of Cold Drawn Seamless Alloy Steel Tubes ASTM A213 ASME A213, designed for use in boilers, superheaters, and heat exchangers.

Engineered to meet the stringent requirements of ASTM A213 and ASME A213 standards, these tubes are known for their exceptional mechanical strength, corrosion resistance, and precision dimensional control. With an outer diameter range from 12.7mm to 115mm and wall thickness from 2mm to 120mm, they are suitable for a wide variety of industrial and mechanical applications.

Advanced Manufacturing and Material Excellence

The Cold Drawn Seamless Alloy Steel Tube ASTM A213 ASME A213 series includes grades such as T11, T12, T22, T91, and T92, all of which are optimized for operation under high pressure and temperature. These alloy steels feature key elements such as chromium (Cr), molybdenum (Mo), and vanadium (V) that enhance their resistance to creep, oxidation, and corrosion.

Each tube undergoes cold drawing, annealing with nitrogen protection, polishing, and ultrasonic testing to ensure internal soundness and consistent surface quality. The end configurations—beveled, plain, or capped—are available per customer requirements, and additional surface treatments like painting, oiling, galvanizing, or phosphating can be applied to extend service life.

Mechanical and Chemical Reliability

According to ASTM A213 and DIN17175 standards, these tubes meet or exceed all mechanical property requirements:

• Tensile Strength: up to 620 MPa

• Yield Strength: up to 440 MPa

• Elongation: 20–30% depending on grade

• Hardness: below 250 HB for high-temperature grades

The precise chemical composition ensures performance stability even under extreme operational conditions. For example, T91 and T92 grades contain up to 9.5% chromium and 1.05% molybdenum, offering superior strength and oxidation resistance at elevated temperatures.

Applications Across Industries

These Cold Drawn Seamless Alloy Steel Tubes are widely used in:

• Boiler systems

• Superheaters and reheaters

• Heat exchangers

• Petrochemical plants

• Power generation equipment

Their ability to maintain mechanical integrity under thermal cycling makes them a preferred choice for critical systems in energy and heavy industries.
