Part Two Medium Manganese Steels: NOTE 9—Although some material may be formed after galvanizing, in general the zinc coating on the articles covered by this speci? Visual inspection of the coating shall be made for compliance with the requirements. Last previous q386 A — 01a.

Purchasers desiring a guarantee of heavier coatings than the minimum thicknesses shown herein should use the special requirements see 4. If the lot is found to 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. 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.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Astn, some articles may have a coating grade at or close to the minimum requirement shown in Table 1. Introduction to Total Materia Integrator 7 th March Within seconds it is also possible for you to find related detailed material property data or search equivalent materials starting from the Total Materia standard list.

In the case of orders in SI units, such shall be stated to the galvanizer when the order is placed. By mutual agreement, the galvanizer is not prohibited from submitting the lot remaining after sorting and removing nonconforming articles without replacement of the nonconforming articles.

Practice A provides guidance on steel selection and discusses the effects of various elements in steel compositions for example, siliconthat in? This standard is subject to revision at any time by the responsible technical committee a836 must be reviewed every? 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. 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.

The galvanizer has only limited control over this condition.

If the lot is found to be nonconforming by the new sample, the galvanizer has the right to sort the lot for conforming articles by individual test, to re-galvanize nonconforming articles, or to renovate the nonconforming articles in accordance with 6. 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.

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 aztm higher requirements with consistency.

A specimen must be evaluated for each steel category and material thickness within the requirements for each specimen of the test article. This shall be achieved by an in-plant inspection program designed to maintain the coating s386 Coatings shall asrm to the requirements of Speci? The specifying of tests for adhesion and embrittlement shall be subject to mutual agreement between the galvanizer and purchaser.
