Stainless Square Tube 304 Welded offers a great mix of strength and corrosion resistance in most situations outside of marine environments. If your project is in a marine environment, choose 316 stainless. 304, the most popular stainless alloy in the world, maintains its properties in high temperature situations. It is typically used in aerospace, food and beverage industry, pressure containers, architectural designs and trim, cryogenic applications, and chemical processing equipment.

This stainless steel square tube measures 3 inches in height with a 0.25 inch wall thickness and a maximum length of 60 inches. It is made from 304 alloy stainless steel, known for its strength and corrosion resistance, and features a #4 finish.

No, the 304 stainless steel alloy is excellent for most applications but is not recommended for marine environments. For marine use, 316 stainless steel is a better choice due to its enhanced corrosion resistance.

Custom cutting is not available for this product as the custom cut warehouse value is 0, indicating it is only sold in standard 60-inch lengths.

Yes, material test reports (MTRs) are available for this 304 stainless steel square tube, ensuring traceability and quality assurance.

This 304 stainless steel square tube is commonly used in aerospace, food and beverage processing, pressure containers, architectural designs, cryogenic applications, and chemical processing equipment due to its strength and corrosion resistance.
