Product description
ASTM 321 Square Structural Welded Stainless Steel ERW Pipe
?
Product Description
ASTM 321 Square Structural Welded ERW Pipe is a square electric resistance welded (ERW) pipe made from 321 stainless steel. 321 is a heat-resistant, titanium-stabilized austenitic alloy known for its good corrosion resistance and high-temperature strength. It is used in a variety of structural applications, including fencing, scaffolding, and general fabrication, and is favored for its strength, corrosion resistance, and toughness at both high and low temperatures.
?
Material Properties (321 Stainless Steel)
Stabilized Alloy: Titanium alloy is stabilized to prevent carbide precipitation, providing resistance to intergranular corrosion.
High-Temperature Strength: Maintains excellent strength and toughness at high temperatures.
Corrosion Resistance: Provides good overall corrosion resistance.
Low-Temperature Toughness: Maintains strength and toughness even at extremely low temperatures.
?
Fabrication Process (ERW)
Electric Resistance Welding: Continuous steel strip is formed into a pipe and joined by passing an electric current through the weld.
Advantages: ERW pipe is known for its uniform thickness, strength, and performance in high-pressure applications.
?
Structural Applications
Construction: Used for fencing, scaffolding, and other general construction applications.
High-Temperature Service: Suitable for high-temperature applications such as furnace components and exhaust systems.
Versatile Fabrication: Its excellent properties make it a versatile choice for a wide variety of fabricated components.
?
Key Features
Shape: Square, providing a flat surface to meet a variety of structural and design needs.
Standard: ASTM A312, General Specification for High-Temperature Stainless Steel Pipe. Grade: 321, selected for its high temperature and corrosion resistance.

Stainless steel pipe is a hollow, long steel section primarily used for industrial pipelines and mechanical components in the petroleum, chemical, medical, food, construction, and instrumentation industries.
Seamless pipe outer diameters range from 6 mm to 762 mm, with wall thicknesses from 0.5 mm to 70 mm.
Annual production is 35,000 tons.
This type of stainless steel pipe offers the following characteristics:
High quality: Smooth, bright, and clean surface.
Precise dimensional tolerances: Precise measurements ensure consistent performance.
High strength: Durable and reliable. High corrosion resistance: Ensures long-lasting performance even in harsh environments.
