DIN6340 Washer/Hardened Steel Washer, M6-M30, Zinc plated/HDG

Standard:DIN6340

Description:

      If you are referring to hardened steel washers in the size range of M12 to M36 with zinc plating or hot-dip galvanizing (HDG), here is some general information about these options:

      1.Zinc Plated: Zinc plating involves applying a thin layer of zinc to the surface of the washer. This coating provides some degree of corrosion resistance and helps protect the underlying steel from rusting. Zinc-plated washers are commonly used in indoor or low-corrosion environments. They are not recommended for prolonged outdoor use or in highly corrosive environments.

      2.Hot-Dip Galvanized (HDG): Hot-dip galvanizing is a process in which the washer is fully immersed in a bath of molten zinc. This results in a thick and durable zinc coating that provides excellent corrosion resistance. HDG-coated washers are commonly used in outdoor applications, especially in construction, where they are exposed to harsh weather conditions, moisture, and corrosive elements. They offer superior protection against rust and have a longer lifespan compared to zinc-plated or plain finish washers.

      When selecting between zinc-plated and HDG-coated hardened steel washers, consider the environmental conditions and the level of corrosion protection required. HDG-coated washers offer superior protection against rust and are generally recommended for outdoor or corrosive environments. Zinc-plated washers are suitable for indoor or less demanding applications.

      It's important to note that the specific DIN standard for washers should be confirmed to ensure the accuracy of the information and to comply with the appropriate standards for your application.
