Supporting Superalloys – A Unique Approach to Powder Metal Cleanliness

Post by:

Superalloys are nickel-based or cobalt-based alloys that are resistant to high temperatures, perform better, are corrosion and oxidation resistant, and last longer than other metals. Superalloy parts are traditionally produced from powdered metals (PM) using subtractive manufacturing techniques. These parts are most often used in heavy industry or in areas having a corrosive environment, as […]

As early as the 1930s, companies were researching the development of duplex grades of steel that were more resistant to cracking and corrosion, but it wasn’t until the 1960s and 1970s when improvement in refining techniques resulted in better product quality, that major progress was made. Since that time, the use of duplex stainless steels […]
