The stainless steel clad steel tube (also called as stainless/carbon steel complex tube) has a stainless steel cladding layer (not electroplating) outside the carbon steel tube to form a two-layer tube. The external stainless steel layer is for the antirust and decoration purposes and the internal layer (carbon steel) is the main part for support. The SUS304 (or other classification) stainless steel and SPHC hot rolled or SPCC coldrolled carbon steel are used for the manufacture of stainless steel clad steel tube.
The roundness of stainless steel clad tube can reach to 0.1±0.05mm and that provides many useful application in precisionindustry like conveyor wheels, fitness & exercise equitment parts, linear actuator and other precision equipment.
Advantages of stainless steel clad tube are from both stainless steel tube and carbon tube-good-looking surface, corrosion- Resistant,high rigidity and lower price. In addition, stainless steel clad tube is a good substitute for electroplating tube due to the trend ofenvironmental protection.
