Stainless steel pipe fittings including Tee,Cross, Elbow, Reducer, Coupling, Nipple, Plug & Cap,Union.They can be connected with pipes by welding, socket and thread.Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd is an experienced steel pipe fitting supplier from China.

 

Stainless steel is created for high temperature/perssure and corrosive environments.It has has superior performance especially in the corrosive environment,design life over 50 years.

 

In appearance,there is a obvious difference between stainless steel and other steel.It is white,so many areas just call stainless steel as “white steel”,and others is “black steel”.Due to its beautiful appearance,polished stainless steel can be a decoration on the surface of building.

 

Annealed condition makes stainless steel better corrosion resistance,so annealed stainless steels are commonly used in some chemical industries.

 

Common stainless steel materials are SS304/304L and SS316/316L,Among them, 304 is the most commonly used.“L” represents the low carbon content in stainless steel.

 

316 VS 304
316 has more salt and corrosion resistance than 304.You can distinguish 316 and 304 by the magnet test.304 will stick with magnets, while 316 and cold worked 304 will not.

 

Stainless steel and Galvanized
Steel is galvanized to prevent corrosion,while stainless steel is inherently resistant to corrosion.Galvanized is more ductile and easier to machine; stainless steel is stronger and more resistant to corrosion.In addition,Galvanized design life always be 20 years,but there is 50 years for stainless.Therefore,stainless is more expensive by its superior properties.
