[ASTM-B] This specification covers requirements for electrodeposited zinc coatings applied to iron or steel articles to protect them from corrosion. It does not cover zinc-coated wire or sheets. High strength steels (tensile strength greater than MPa) shall not be electroplated.

Dec 10,  · Zinc, a natural, healthy, and abundant element was first used in construction in 79 certifiedneighborhoodspecialist.com metal has a number of characteristics that make it a well-suited corrosion protective coating for iron and steel products. Zincsexcellent corrosion resistance in most environments accounts for its successful use as a protective coating on a variety of products and in many exposure conditions. Gives guidelines and recommendations regarding the general principles of design which are appropriate for articles to be zinc coated for corrosion protection and the level of corrosion resistance provided by zinc coatings applied to iron or steel articles, exposed to a variety of environments.

Designation: B – 98 e 1 Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel 1 This standard is issued under the fixed designation B ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. The basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard, BS () (European standard under development: pr EN ). To ensure the best quality and technical backup service, it is recommended that the work is processed by a member of the Galvanizers Association. Zinc Plating.

production is used in zinc coatings to protect steel from corrosion. Because zinc is an infinitely recyclable material, the level of recycling increases each year, and currently 80% of the zinc available for recycling is indeed reclaimed.

However, because of zinc’s excellent field performance as a. buy bs (): specification for hot dip galvanized coatings on iron and steel articles from sai global. resistance provided by zinc coatings applied to iron or steel articles, exposed to a variety of environments.

Initial protection is covered in relation to ⎯ available standard processes, ⎯ design considerations, and ⎯ environments for use. This part of ISO applies to zinc coatings applied by the following processes. Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless1 This standard is issued under the fixed designation A53/A53M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

This specification covers zinc coatings applied by the hot-dip process on iron and steel hardware. The hot-dip galvanizing process consists of parts being immersed in molten zinc for a sufficient time to allow a metallurgical reaction between iron from the steel surface and the molten zinc, resulting in the formation of Zn/Fe alloy layers bonding the coating to the steel surface.
