DAMORPHE’s materials innovation platform with novel manufacturing and processing approaches have enabled tailoring of alloys with excellent physical properties, for example: strength, corrosion resistance, resistance to environmental assisted cracking (EAC) / hydrogen embrittlement (HE) at an attractive price point for O&G.
Corrosion Resistant Alloys
“Resistant to cracking”
Current offerings of corrosion resistant alloys (CRAs) for O&G, produced by conventional ingot metallurgy (IM) have yield strengths of 40ksi for Stainless Steels (SS) and 80-120ksi for Ni-alloys. Through unique processing, we have successfully augmented their strengths to 120ksi for SS and 240ksi for Ni-alloys with the same chemistry. Further enhancements have been achieved via grain boundary engineering (GBE) yielding 300ksi Ni-alloys. These technologies enable the design lighter-stronger products with a smaller footprint or thin-walled vessels of exceptional pressure ratings, where real estate is a concern.
Our proprietary CRAs are more resistant to general corrosion (due to abundance of low ΣCSL grain boundaries, courtesy of GBE), and less susceptible to EAC/HE or damage when compared to their coarse-grained commercial counterparts in both upstream and downstream extreme environments (i.e. environments rich in hydrogen sulfide (H2S) at high temperature, high pressure) common in O&G.
We are re-engineering in nuclear, chemical and high temperature carbon rich gaseous environments (metal dusting) by designing apposite nanostructures. This offers the possibility of not only enhancing their strength or ductility but also their corrosion, cracking and erosion resistance. Applications encompass Transportation, Space and Defense, among others.
