CDS tube for honing

CDS tube is a cold drawn 1020 to 1026 or ST52.3 grade electric resistance welded tube with all the flash removed prior to drawing to size. Cold drawing DOM to size allows for higher yield and tensile strengths. In comparison to other tubing, DOM is produced to more exact OD and ID tolerances. This allows for minimal machine time and has the highest weld strength possible.
