409 stainless steel is a ferritic stainless steel commonly used in machinery, construction and other projects.
410 stainless steel tube has good corrosion resistance and machinability, and is generally used as a cutting tool.
420 seamless tubes are used to manufacture parts for resistant to atmospheric, water vapor, water and oxidative acid corrosion.
430 stainless steel has good corrosion resistance,commonly used in heavy oil burner parts, household appliances, and household appliance parts.
439 seamless tube mainly used for automotive exhaust system components, washing machine inner cylinder, etc.
440 material is mainly used to manufacture bearing parts that work in corrosive environments and non-lubricating and strong oxidizing atmospheres.
446 seamless pipe is mainly use for furnace parts,oil burner components,annealing boxes etc.
Manufacturing process：
Round tube billet → heating → perforation → head → annealing → pickling → oiling → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydraulic test (inspection) → mark → in Library.
