  • Reducing Hydrogen Embrittlement Risk of Steel Bolting in Seawater Environment with Nickel-Cobalt Electroplating

    June 25th, 2018

    Among the several threats to bolting in marine environments, hydrogen embrittlement is one of the most dreaded. A form of environmentally assisted cracking (EAC), hydrogen embrittlement occurs when hydrogen penetrates a fastener’s base material, making i... READ MORE >>

  • Nickel-Cobalt Alloy Coating Protects Steel Fasteners from Hydrogen Embrittlement

    June 14th, 2018

    At the beginning of the year, Kathy Riggs Larsen of Materials Performance spoke with Doxsteel Corrosion specialists Omar Rosas and Oscar Garcia about the dangers of hydrogen embrittlement. A form of stress corrosion cracking (SCC), hydrogen embrittlement occur... READ MORE >>

  • How ASTM B994 Bolting Eliminates the Need for Metal Disintegration

    May 30th, 2018

    When fasteners seize, facilities require costly and time-consuming processes to free and replace them. Turnaround operations that are executed in days on unseized bolts end up taking weeks when replacing seized fasteners, leading to facility downtime that can ... READ MORE >>

  • How to Protect Your Bolts from High Temperature Environments and Liquid Metal Embrittlement

    May 30th, 2018

    Liquid metal embrittlement occurs when extreme high temperatures bring fastener coatings to their melting point. As the coating liquifies, it induces a loss in the bolt’s tensile ductility, causing it to become brittle and highly susceptible to fracture. Fas... READ MORE >>

  • We’re In: Why the Major Oil & Gas Companies are Adding New Bolting Vendors for the First Time in 20 Years

    April 12th, 2018

    In the past 20 years, no major companies in the oil & gas industry have added new bolting specifications to their Approved Manufacturer Listings (AML). Companies like Shell, Chevron, MRC Global, Anadarko, BHP Billiton, BASF, and Chemours have installed and rep... READ MORE >>

  • Why ASTM B994 is the World’s Best Bolting Solution

    March 6th, 2018

    With the industry in search of better methods to protect fasteners from failure, ASTM B994 offers a novel solution to corrosion resistance in bolting operations. Suggesting a Nickel-Cobalt alloy as the new practice for fastener electroplating, ASTM B994 is des... READ MORE >>

  • The Journey of a Fastener

    March 6th, 2018

    Many of the problems that challenge bolt reliability in the industry today come from a lack of knowledge and communication. Steel is formed by one company, purchased by another, sent to yet another for coating by uncontrolled processes, then shipped to sites i... READ MORE >>

  • Installation Recommendations for Optimum Performance

    March 6th, 2018

    Fasteners seize because oxide (red rust corrosion) accumulates in the thread engagement between the stud and the nut. When this occurs, removing the fastener from assembly usually requires cutting, torching, or grinding. In addition to ballooning a facilit... READ MORE >>

  • Case Study: ASTM B994 Nickel-Cobalt vs. Legacy PTFE Blue Bolts

    March 6th, 2018

    We recently received a report from one of our customers on the performance of our ASTM B994 Nickel-Cobalt bolting that perfectly illustrates both the toughness of our coating and the benefit of painting the exposed sections of the bolting after assembly. This ... READ MORE >>

  • The Dangers of Hot Bolting

    David Dunning is a Cornell University professor who is perhaps most famous for a paper he co-wrote about ignorance and over-confidence.

    The Dunning-Kruger effect refers to people who are novice or ignorant to things they do not know but believe they are expert
