The difference between hot dip galvanizing and cold dip galvanizing

The difference between hot dip galvanizing and cold dip galvanizing

Hot-dip galvanizing pipe reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to in a hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.

What are the properties of stainless steel plates?

What are the properties of stainless steel plates?

The stainless steel plate has a general corrosion resistance similar to that of the unstable ni-Cr 304. Prolonged heating in the temperature range at chromium carbide levels may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, which require strong resistance to sensitization of materials to prevent intergranular corrosion at lower temperatures.
