What is 304 No. 4 finish pipe?
304 No. 4 finish stainless steel pipe is a brushed finish commonly found on kitchen appliances and backsplashes. 304 No. 4 finish stainless steel pipe has a PVC film to help prevent scratching during manufacturing and installation.
What is the difference between 304 2B and 304 4 finish pipe?
The main difference is appearance and processing: a 304 2B finish is a smooth, slightly reflective, and more uniform "cloudy" finish, produced by light cold rolling. A 304 #4 finish (often called "brushed") has a non-reflective, dull appearance with visible, parallel linear grain lines, created by mechanical polishing after the 2B process.
