29.09.2010You should make sure why cadmium is being requested. It is a restricted substance for many applications and is being replaced for fastener usage by many end users with many different coatings. ASTM A 325 usually is specified plain or zinc coated (hot dipped galvanized, mechanical galvanized, inorganic Zn).

This type of cadmium plating has a phosphate supplementary colorization and is usually employed as a paint base. Cadmium plating classifications are divided into 1, 2, and 3, based on the thickness of the coating. For example, class 1 is a coating of 0.0005 in., class 2 is 0.0003 in., and class 3 is rated at 0.0002 in. Cadmium Plating Expertise

Zinc nickel coatings work in almost an identical way to cadmium in that it provides a sacrificial coating to protect against corrosion and is applied via electroplating. Zinc is the sacrificial element within the coating, but on its own it is too active and corrodes too easily. This is why between 12 and 16% nickel is added in order to slow the

25.11.2019Stainless steel is an iron alloy composed primarily of iron and chromium. The chromium in the material reacts with oxygen on the surface to create an oxidized "passive layer", which prevents corrosion and rust. While all stainless steels have at least 10.5% chromium content, alloys with higher percentages demonstrate greater corrosion resistance. Stainless
