--------Flexible Exhaust Pipe Material


SUS 304 Austenite stainless steel is usually referred to as the Japanese name for SS304 or AISI 304 stainless steel.304 stainless steel is a common material of stainless steel, the density of 7.93 g/cm3 and resistance to high temperature 800 ° C.It has good processing performance and high toughness.They are widely used in medical industry and furniture decoration industry and food industry.

Flexible metal hose made with ss304 has good comprehensive performance of corrosion resistance and formability.Stainless steel 304 flexible metal hose  is durable in use , good and inexpensive, will bring the best result of use and good economic benefits to you.


ss321 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816° C).

ss321 also advantageous for high temperature service because of its good mechanical properties. sss321 offers higher creep and stress rupture properties than ss304.Therefore,if your tube needs to work under high temperature conditions, please select the flexible metal hose made by ss321.


ss316L  is an extra-low carbon version of the 316 steel alloy. SS316L has good corrosion resistance and is resistant to marine and aggressive industrial atmospheres.The lower carbon content in 316L minimizes deleterious carbide precipitation as a result of welding.

316L stainless steel has a maximum carbon content of 0.03. If it cannot be annealed after welding and the corrosion resistance is extremely high, Stainless steel flexible metal hose will be your best choice.
