BS EN 2516 specifies several chemical methods of passivation for corrosion resisting steels (austenitic, ferritic, martensitic and precipitation hardenable) and of decontamination for a nickel or cobalt-base alloys.
Adopting these methods can enable you to determine the corrosion-resistant properties in steel parts for optimal performance in aerospace applications.
Note: Passivation shall not be used on castings, welded or brazed parts, carburized or nitrided surfaces nor on parts with mating surfaces when entrapment of acids may occur.
BS EN 2516 on passivation of corrosion resisting steels and decontamination of nickel-base alloys is applicable to:
BS EN 2516 covers methods of passivation for corrosion resisting steels and of decontamination for nickel or cobalt-base alloys. It creates a standardized approach for manufacturers of steel and nickel base alloy to adhere to if they supply their metallic materials for use by the aerospace and defence industry.
By adopting BS EN 2516, manufacturers can demonstrate the reliability of their steels and nickel base alloy and build trust in its use throughout the aerospace supply chain.
With BS EN 2516, you can assess the corrosion resistant resistance characteristics of a part after such treatments as machining, forming, tumbling and shot peening by removing foreign metal contamination due to these operations. As a result, you can select the right materials for your applications for overall success of the end-application. BS EN 2516 can also support your product development and research initiatives.
