In addition, the purchaser should anticipate the need for test batches or extra preparation steps, or both, such as blasting before galvanizing or other methods, to attempt to reach the higher requirements with consistency. NOTE 2—The presence in steels and weld asgm, in certain percentages, of some elements such as silicon, astj, and phosphorus tends to accelerate the growth of the zinc-iron alloy layer so that the coating may have a matte?

These designations often apply to specific products, for example A is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws. This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,? Metallic coated carbon steel wire coated at size for mechanical springs Composite ribbed steel pipe, pre-coated and polyethylene lined sewer pipe application Flexible poly vinyl chloride PVC gaskets used in connection of water closets to sanitary drainage system For more information on the ASTM designation system see our related article: Lumps, projections, globules, or heavy deposits of zinc which will interfere with the intended use of the material will not be permitted.

The elements can be added to the galvanizing bath as part of a pre-alloyed zinc feed, or they can be added to the bath by the galvanizer using a master feed atsm. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The average of the? Individual reprints single or multiple copies asstm this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Release DataPLUS, a new module providing corrosion data, material joining information, material dimensions and tolerances and coatings information helps drive even more accurate material selections! The pieces shall be handled so that after galvanizing they will not freeze together on cooling.

Our mission is simple; to make Total Materia the one-stop place and first choice of engineers world wide. NOTE 3—The galvanizer may choose to add trace amounts of certain elements for example, aluminum, nickel, and tin to the zinc bath to help in the processing of certain reactive steels or to enhance the a86 appearance of the?

Total Materia has allowed us to solve in a definite way all problems we had for the search of alternate materials in foreign countries.

The zinc coating on threaded components of articles galvanized under this speci? Originally published as A — 28 T. NOTE 5—Inaccessible surface areas are those which cannot be reached for appropriate surface preparation and application of repair materials as described in Practice A Inspection, Rejection, and Retest 9. It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena. Internal threads are not prohibited from being tapped or retapped after galvanizing.

The galvanizing of separate reinforcing steel bars shall be in accordance with Speci?

The galvanizer shall afford the inspector all reasonable facilities to satisfy him that the zinc coating is being furnished in accordance with this speci? If a sample x386 taken as representing the lot for acceptance, the sample shall be taken at random from the lot without regard sstm the perceived quality or appearance of any individual unit in the lot being sampled.

In the case of any such local section containing more than one material category or steel thickness range 3a86 delineated in Table 1, that section will contain asttm than one specimen see Fig. This new sample shall be measured using magnetic thickness gages which have been calibrated for accuracy against reference material thickness standards.

NOTE 7—Items which zstm prepared for galvanizing by abrasive cleaning will generally develop a thicker coating with a a3886 rougher surface.
