The Stainless Steel Square Pipe is highly durable and resistant to mild corrosion. With a minimum yield strength of 205MPa and a minimum tensile strength of 515MPa, it can withstand temperatures up to 870 degrees Celsius. The 316 grade is preferred in aqueous and chloride ion rich environments due to its superior corrosion resistance compared to the 304 grade. The addition of molybdenum in the 316 grade enhances its resistance to chloride ion corrosion. The 304 grade is the most cost-effective option among stainless steel pipes. The weight of the pipes is influenced by factors such as wall thickness, outer diameter, and material density. Our SS Square Pipe Weight Chart provides detailed information on the correlation between different grades, diameters, thicknesses, and weights per unit length. For more information on Stainless Steel Welded Square Pipes and pricing, please get in touch with us. Stainless Steel Square Pipe is available in various grades and is ideal for structural applications, offering additional strength due to its geometric shape.

**Stainless Steel Square Pipe** supplied by Piping Material comes in various sizes and meets ASTM, ASME, and API standards. The popular grade is 304 stainless steel, with the ASTM A554 Grade Mt304 Tube being a common choice. It offers strong corrosion resistance to mild agents, with a minimum yield strength of 205MPa and minimum tensile strength of 515MPa, operating at up to 870 degrees Celsius. For more corrosive environments, the 316 Stainless Steel Square Tube is recommended due to its added molybdenum for improved corrosion resistance against chloride ions. The 304 Stainless Steel Square Pipe is a cost-effective option, and the weight of the pipes varies based on wall thickness, outer diameter, and material density. Check our SS Square Pipe Weight Chart for more details on grades, diameters, thicknesses, and weights per length. Contact us for information on Stainless Steel Welded Square Pipes and pricing.
