It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Our Zinc coating is carried out according to: Please first verify your email before subscribing to alerts. High aastm steels tensile strength greater than MPa shall not be electroplated. If these heat treatments are not required, the purchaser shall specify in the ordering asm their exception 5.

As the voice of the U. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The baking treatment shall be done before the application of the supplementary treatments and within 4 h of removal from the last process.

NOTE 4—The dimensional tolerance of most threaded articles, such as nuts, bolts, screws, and similar fasteners with complementary threads, normally does not permit the application of a coating thickness much greater than 8.

Guide B provides a default plan if one is not speci? For corrosion resistance requirements, see Table 2. SC 4 very severe. If heavier coatings are required, allowance for the deposit buildup aztm be made during the manufacture of the threaded articles. 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 black layer has also additional target —prevention of light reflection from the part and is used for optical parts.

It does not cover zinc-coated wire or sheets. Zinc coating with colorless RoHS compliance passivation.

ASTM B – 07 Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel

Corrosion Resistance Requirements Types. The coating shall not be stained or discolored. Zinc 70 with colorful chromate passivation. The type of passivation is determined according to the required characteristics, and is divided into groups: Iron metals rust relative quickly, even in a non-corrosive environment. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

The coating is made according to demand, where the distribution is as follows: The procedure is known as sampling inspection. The test must yield a numeric value and certain statistical requirements must be b6633.

ASTM B – Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel

This guide provides for two plans: Due to the n633 of forging or casting separate test specimens, hot-rolled steel specimens may be used to represent forged and cast steel articles. Olive green passivation is a chromate passivation in a green hue that gives excellent corrosion resistance ability hours in a salt asmt test and is a good base for paint. Go to main content. The type of passivation is determined according to the required characteristics, and is divided into groups:.

As a result of large-scale and long-range tests conducted by ASTM and other organizations, there is excellent information on the corrosion behavior of zinc and zinc coatings. Your Alert Profile lists the documents that will be monitored.

For these reasons a?

The rust not only harms the aesthetically smooth look, but also its mechanic needs. The sampling plan used for the inspection of the quality coated article shall be agreed upon between the purchaser and producer. Colorful chromate passivation gives corrosion resistance ability of 96 hours according to ASTM B until white spots-intended to parts used in a high corrosive environment —outdoor.

A Iron or steel with zinc electroplate.

Zinc Coating

Zinc plated components vary from one industry to another. Zinc coating with colorful RoHS compliance passivation. The electrical resistance of this green layer passivation is very high because it is thick in relative to other passivations. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

These methods would include BBand B The purchaser retains the right to perform any of the inspections and tests set forth in this speci? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Responsibility for Inspection S1. The designer and engineer must take into account several considerations to stay at the forefront of the finish potential.

Olive green and Black passivation is thick and has high electrical resistance. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
