Co-based alloys have played an important role in oil drilling for many years. They are mostly used for resisting wear and corrosion in various forms, including castings, weld overlays, and wrought sheets and bars. These alloys typically contain Cr, W and/or Mo. Most of them contain relatively high C content in order to increase hardness for wear resistance but at the expense of corrosion resistance. The alloying elements must be properly balanced to satisfy the requirements of both corrosion and wear resistance for a given application in oil drilling. The issue of sulfide stress corrosion cracking has not been well studied for these alloys since they are mostly used in conditions that are not subject to such cracking. However, this needs to be clarified. This paper examines the effects of the alloying elements of the Co-based alloys on the microstructure and their performance in laboratory tests as well as various applications in oil drilling. Both traditional and recently developed alloys are included. The test results of sulfide stress corrosion cracking of these alloys are also presented and discussed.

A for fitness-for-service evaluation was conducted in simulated seawater injection conditions for three levels of dissolved oxygen (30, 50, and 100 ppb) to assess the effect of upsets in control of the deaeration. Four materials were studied:  austenitic UNS S31603, duplex UNS S39274, and two nickel base alloys

In a 1998 study, costs for corrosion in USA were estimated to be about 276 billion US-$.  One way to reduce this gigantic amount of money is to use modern stainless steels and nickel alloys with excellent resistance to various forms of corrosion in corrosive environments like seawater, brines, oil and sour gas wells.
