ASTM Standard List: Coated Steels :: Total Materia Article

The other values are based on conversions using the following formulas: NOTE 9—Although some material may be formed after galvanizing, in general the zinc coating on the articles covered by this speci? NOTE 2—The presence in steels and weld metal, in certain percentages, of some elements such as silicon, carbon, 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. Practices AAand A provide guidance for steel fabrication for optimum hot dip galvanizing and shall be complied with in both design and fabrication. Our mission is simple; to make Total Materia the one-stop place and first choice of engineers world wide.

Materials and Manufacture 5. The adhesion shall be considered inadequate if the coating? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The specifying of tests for adhesion and embrittlement shall be subject to mutual agreement between the galvanizer and purchaser. A number in parentheses indicates the year of last reapproval.

Plain holes of 1? In such cases, the precision and accuracy of the coating thickness measuring technique should be taken into consideration when rejecting such articles for coating thickness below that required by this speci?

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 cosmetic appearance of the?

By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard. While most coating thicknesses will be in excess of those values, some materials in each category may be less reactive for example, because of chemistry or surface condition than other materials of the steel category spectrum.

The mass, shape, and amount of cold working of the product being galvanized may also affect this condition. Practice A provides guidance on steel selection and discusses the effects of various elements in steel compositions for example, siliconthat in?

Otherwise, the test specimens shall be selected at random from each lot. It is the atm of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena.

These inclusions are raised surfaces and are easily knocked off FIG. The average of the? Therefore, some articles may have a coating grade at or close to the minimum requirement shown in Table 1.
