Carbon Steel Materials Applied for Perforated Tubes Manufacturing:
Stainless Steel, unlike carbon steel, is corrosion resistant. It contains chromium which, when exposed to oxygen, creates an invisible protective film. Stainless steel types are classified into
three different groups based on their ability to be hardened. Austenitic stainless steels, which can be hardened by cold working, meet a wide range of design criteria. They are essentially
non-magnetic, although they may become slightly magnetic due to cold working.
Because carbon steel is susceptible to corrosion, it is typically used in either unexposed applications or protected with a coating. Coatings such as paint and powder are applied after
perforating and completely protect the material. Zinc based coated metals (i.e. Galvanized, Galvannealed, etc.) on the other hand, are produced and supplied as such from the mill and may not
completely protect the material where its carbon core is exposed during the perforating process.
Commonly Perforated Carbon Steel Types
Commercial Steel (HR, CR, GALV) A low cost steel that has good drawing, forming, and welding qualities, moderate strength, but is subject to strains, fluting, and breaks due to aging. To reduce
the affects caused by aging, Drawing Steel is recommended.
