Many of us are familiar with examples where a particular alloy was correctly selected for a certain component, yet it corroded or failed mechanically prematurely because of improper fabrication or field installation. Most can appreciate that duplex stainless steel alloys require somewhat modified fabrication procedures compared to standard austenitic alloys. However, there are significant differences in the proper fabrication procedures within the duplex family - lean duplex grades are different than standard duplex which are different than superduplex stainless steels. Sometimes with the same alloy, differences in fabrication procedures for one end use may need to be modified for another end use. For example, fabrication of 316L for an application in the food industry would not be fabricated identically to 316L for a sulphuric acid tank nor for a structural application in a bridge. It is important that not only the fabricators are aware of what constitutes good fabrication, but also designers, specifiers and end users.
The Nickel Institute provides many different tools to help in proper fabrication of different nickel-containing materials. We offer Publications on stainless steels, nickel-base alloys and copper-nickel alloys. There are a few publications also on less common materials. Often understanding the properties of the particular material is the first step to understanding how it behaves in various hot and cold forming or joining operations. Otherwise, feel free to contact us.
This section of the website will be expanded in due course. In the meantime, have a look at our related Publications, our Knowledge Base tools, and our related Nickel Magazine stories.
