The stainless steel composite pipe is made of stainless steel and carbon structural steel. The new material is made of non-destructive pressure synchronously. It has stainless steel corrosion-resistant and wear-resistant appearance and excellent appearance. It also has good bending strength and impact resistance of carbon steel.316L stainless steel pipes supplier . Meet the principle of energy saving and popularization. The stainless steel composite pipe was officially promulgated in the 2002 standard GB/T18704-2002. It has a set of strict and standardized management from the aspects of material quality selection and inspection. Due to its beautiful appearance and low price, it has been widely used in bridge guardrails. Decoration, vehicle accessories, conveyor rollers, textile machinery accessories and other fields.
Stainless steel composite pipe guardrails are usually divided into base structures:
Ferritic stainless steel. Containing 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase the resistance to chloride stress corrosion with the increase of chromium content compared with other types of stainless steel.
Austenitic stainless steel. Containing more than 18% chromium, it also contains about 8% nickel and a small amount of elements such as molybdenum, titanium and nitrogen. Good overall performance, resistant to a variety of media corrosion.
Austenitic ferrite duplex stainless steel. It combines the advantages of austenitic and ferritic stainless steels and has superplasticity.
Martensitic stainless steel. High strength, but poor plasticity and weldability.
