Articles Dynamic Strain Aging of Steels: Dynamic Strain Aging of Steels: In the case of orders in inch-pound units, the measured value shall be converted to coating grade units by the use of Table 2.
Enter a phrase to search for: Some higher-than-standard thicknesses may be impractical or unattainable. Such a plan is contained in Test Method B which addresses sampling procedures for the inspection of electrodeposited metallic coatings and related?
Materials and Manufacture 5. A number in parentheses indicates the year of last reapproval.
This new sample shall be measured using magnetic thickness gages which have been calibrated for accuracy against reference material thickness standards.
By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard. Originally published as A — 28 T.
Do not use testing carried out at edges or corners points of lowest coating adhesion to determine adhesion of the coating. The other values are based on conversions using the following formulas: The average of the?
ASTM A – Withdrawn Specification for Zinc Coating (Hot-Dip) on Assembled Steel Products
The galvanizing of separate reinforcing steel bars shall be in accordance with Speci? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
However, by agreement the purchaser is not prohibited from making tests which govern the acceptance or rejection of the materials in his own laboratory or elsewhere. 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!
Within the text of this speci? In this case, the minimum number of specimens from each lot shall be as follows: Current edition approved October 10, Otherwise, the test specimens shall be selected at random from each lot. Since surface smoothness is a relative term, minor roughness that does not interfere with the intended use of the product, or roughness that is related to the as-received un-galvanized surface condition, steel chemistry, or steel reactivity to zinc 5 6.
Except for local excess coating thickness which would interfere with the use of the product, or make it dangerous to handle edge tears or spikesrejection for nonuniform coating shall be made only for plainly visible excess coating not related to design factors such as holes, joints, or special drainage problems see Note 6.
ASTM Standard List: Coated Steels
Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4. It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena.
Unless otherwise agreed upon between the galvanizer and the purchaser, or established within this speci? Surface conditions related to de?

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?
In such case, the now-smaller lot shall be treated as a new lot for purposes of inspection and acceptance. 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 alloy.
Introduction to Total Materia Integrator 7 th March For thickness testing purposes, articles whose surface area is greater than in. They do not address the matter of measured coating thickness variations that can be encountered because of different steels or different thicknesses of a given steel being used in an assembly.
This shall be achieved by an in-plant inspection program designed to maintain the coating thickness,?
In the case of an article containing more than one material category or steel thickness range as delineated in Table 1, that article will contain more than one specimen, as appropriate see Fig. Inspection, Rejection, and Retest 9. The axtm consists of one or more test articles. Click here to see more. New Developments in Total Materia 10 th January The specifying of tests for adhesion and embrittlement shall be subject to mutual agreement between the galvanizer and purchaser.
