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