“Originally, we had specified a chrome plating in our cylinder cap for mounting our gas injection valve, but it could not always stay tight as there were high requirements for chrome surface quality,” said Per Brandt, manager at MAN Diesel & Turbo. “We tried unsuccessfully with different solutions. Fortunately, someone had heard about Expanite's surface hardening, and although stainless steel is usually softer than chrome surface, it turned out to be the solution. A design change coupled with Expanite's hardening technology solved our challenge.
“In cooperation with Expanite we relatively quickly found a hardening that made our surface resistant against scratches and corrosion. The solution passed our test in service where the system remained sealed and tight.”
According to Expanite, its surface hardening technology makes stainless steel extremely wear and corrosion resistant.
Expanite is a Danish growth company established in 2010.
Expanite has already established service centers in Denmark, Germany, the U.S. and China.
