Disadvantages of Mild Steel Pipe

Mild steel pipe cannot be hardened by heat treatment. Heat treatments only affect carbon. If there's not enough carbon in a steel, there won't be any significant improvements.   Mild steel pipe isn't as strong as carbon steel tubing. Its ductility is also a disadvantage - mild steel cannot be used in highly stressful applications such as infrastructure or construction.   If your product is for low-stress applications and designed for consumer use, you might benefit from mild steel pipe's low cost and light weight qualities. We would not recommend mild steel for high-stress applications.
