Decoration 8 Inch 201 202 Duplex Ss316 Ss304 Welded Seamless Hollow Section Stainless Steel Square Pipe
Stainless steel is the iron alloy that is with chromium element of about 10.5%.
Chromium alloy is producing oxide thin layer at the steel surface that is called a passive layer.
This is thus preventing corrosion of the product surface.
Increase in the chromium amount provides the greater corrosion resistance.
Stainless steel alloy is also containing different amount of alloys namely manganese, carbon and silicon.
