A basecoat is typically the first layer of paint or other coating material that serves as the base on which the top or finishing coat is applied. If a primer coat is required, the basecoat is applied over it.The basecoat type (water-based or solvent-based) depends on the type of top or finishing...
18/8 stainless steel is the most widely used and flexible austenitic form of stainless steel. The numbers 18/8 represent the composition of this steel; it is 18% chromium and 8% nickel, making it very resistant to corrosion and oxidation.18/8 stainless steel is also highly durable and easy to...
Chemical oxygen demand is the amount of oxygen needed to oxidize the organic matter present in water. Chemical oxygen demand testing is used to determine the amount of oxidation that will occur and the amount of organic matter in a water sample. Chemical oxygen demand testing is also used to...
Chloride stress corrosion cracking (Cl-SCC) is the most common type of environmentally-induced cracking of austenitic stainless steel. It has been the observed cause of metal failure in numerous scenarios.
