Overview
Type 304 is the most widely used austenitic stainless steel, known for its balanced properties. Its composition, primarily 18% chromium and 8% nickel, creates a passive layer that provides exceptional resistance to corrosion from atmospheric conditions, chemicals, and food products. This non-magnetic alloy maintains its strength and toughness at both elevated and cryogenic temperatures, making it a versatile choice for a wide range of environments.
As rectangular tubing, the 304 grade offers high strength-to-weight ratios and superior torsional resistance, ideal for building durable frames, supports, and railings. Its clean, smooth surface finish makes it suitable for architectural and decorative applications where aesthetics are important. The material's excellent formability allows for bending and shaping without compromising its structural integrity, providing flexibility for complex fabrication projects.

Common Applications
- Architectural & Construction: Handrails, support columns, window frames - Excellent corrosion resistance and aesthetic appeal.
- Food & Beverage Processing: Equipment frames, conveyor supports, dairy tubing - Resists corrosion from food acids and cleaning solutions.
- Marine Environments: Boat railings, ladders, hardware supports - Good resistance to saltwater corrosion.
- Automotive: Exhaust system components, roll cages, chassis reinforcement - High strength and heat resistance.
- Medical Equipment: Carts, frames for diagnostic machines, bed frames - Hygienic and easily sanitized surface.
- General Fabrication: Brackets, structural supports, machine guards - High strength and ease of welding.
- Furniture: Table legs, chair frames, shelving units - Modern aesthetic and durability.
Working with Type 304 Rectangular Tubes
Machining
Type 304 has fair machinability but is prone to work hardening. Use sharp tools, slow speeds, and heavy, constant feeds to prevent glazing. The use of a chip breaker is recommended to manage the tough, stringy chips produced.
Welding
Exhibits excellent weldability by all standard fusion methods, both with and without filler metals. Post-weld annealing is not required to restore corrosion resistance for most applications, though it can relieve stresses from heavy weld sections.
Finishing
Can be supplied with a standard mill finish or polished to various grits for aesthetic applications. The surface is non-porous and easily cleaned or sterilized, making it suitable for sanitary applications.

Frequently Asked Questions
Q: What is the difference between 304 and 316 stainless steel rectangular tube?
A: Both offer excellent corrosion resistance, but 316 contains molybdenum, which significantly enhances its resistance to chlorides and pitting, making it superior for marine or chemical processing environments. 304 is more cost-effective for general-purpose applications.
Q: Is 304 rectangular tube suitable for outdoor railings?
A: Yes, Type 304 is an excellent choice for outdoor railings due to its high resistance to atmospheric corrosion. It maintains its appearance and structural integrity for years with minimal maintenance. For coastal or high-salt environments, Type 316 is recommended.
Q: Is this tube welded or seamless?
A: Most 304 rectangular tubing is produced by welding from flat-rolled stainless steel. This process provides tight dimensional tolerances and a high-quality surface finish suitable for structural and architectural use. For specific seamless requirements, please contact us.
