China Supplier 201 202 204 Stainless Steel Tube
The Rockwell hardness test of stainless steel pipe is the same as the Brinell hardness test, which is an indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is a widely used method at present, and HRC is second only to Brinell hardness HB in steel pipe standards. Rockwell hardness can be applied to the determination of very soft to very hard metal materials, it makes up for the Brinell method is not, is simpler than the Brinell method, can directly read the hardness value from the dial of the hardness machine. However, due to the small indentation, the hardness value is not as accurate as the Brinell method.

60.3*2.5mm Welded Galvanized Gi Iron Steel Pipe Price From China Factory
Galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube base and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
