ASTM Standard List: Coated Steels
New Developments in Total Materia 10 th January With Total Materia finding information about a metal standard specification, its current status and the materials it defines is one click away. Within seconds it is also possible for you to find related detailed material property data or search equivalent materials aztm from the Total Materia standard list. Enter a phrase to search for: Lumps, projections, globules, or heavy deposits of zinc which will interfere with the intended use of the material will not be permitted.
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.
If the lot size is such that the sample size cannot be doubled, then the sample size shall be as previous, but the number of widely dispersed sites at which measurements were made shall be doubled, and these sites will constitute the new sample.
Visual inspection of the coating shall be made for compliance with the requirements. Inchpound units and SI units are not necessarily exact equivalents. Surface conditions related to de? It is the responsibility of the purchaser to heat treat or otherwise allow for the possibility of such embrittling phenomena. Such a plan is contained in Test Method B which addresses sampling procedures for the inspection of electrodeposited metallic coatings and related?
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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. Materials and Manufacture 5. The requirements for malleable iron castings to be galvanized shall be as stated in Speci?
Introduction to Total Materia Integrator 7 th March The mass, shape, and amount of cold working of the product being galvanized may also affect this condition. Closed Rib Steel Pipe with Diameter of 36 in. Our mission is simple; to make Total Materia the one-stop place and first choice of engineers world wide.
They do not address the matter of measured zstm thickness variations that can be encountered because of different steels or different thicknesses of a given steel being used in an assembly. In the case of orders in SI units, the values in Table 1, shall be applicable as metric units in micrometres. Inspection, Rejection, and Retest 9.
This standard has been approved for use by agencies of the Department of Defense.
NOTE 1—Each specimen comprises nominally one third of the total surface area of the article. If a sample is taken as representing the lot for acceptance, the sample shall be taken at atm from the lot without regard to the perceived quality or appearance of any individual unit in the lot being sampled. Practices AAand A provide guidance for steel fabrication for optimum hot dip galvanizing and ast be complied with in both design and fabrication.

These tests shall not be required unless strong evidence of embrittlement is present. If Test Method B is used, the level asttm sampling shall be agreed upon between the galvanizer and the purchaser at the time the coating order is placed. Last previous edition A — 01a. In the case of an article containing more than one material category or steel thickness range as delineated in Table 1, that article w386 contain more than one specimen, as appropriate see Fig.
The specifying of tests for adhesion and embrittlement shall be subject to mutual agreement between the galvanizer and purchaser. If the lot is found aa386 be nonconforming by the new sample, the galvanizer has the right to sort the lot for conforming articles by individual test, to re-galvanize non-conforming articles, or to renovate the nonconforming articles in accordance with 6.
The galvanizer shall afford the inspector all reasonable facilities to satisfy him that the zinc coating is being furnished in accordance with this speci?
NOTE 4—The coating thickness grades in Table 1 represent the minimum value obtainable with a high level of con?
For each specimen as a36 in 3. The zinc coating on threaded components of articles galvanized under this speci? The thickness thus determined is a point value. The adhesion shall be considered inadequate if the coating?
