The transition to cheaper and more environmentally friendly fuels is crucial to the future of the shipping industry, and MAN Energy Solutions is a major player in that market.<\/strong><\/em><\/p>\r\n\r\n MAN Energy Solution’s newest generation of gas driven engines already plays a key role in the sector’s fuel conversion from oil to alternative energy. When developing the engine, Expanite and MAN Energy Solutions collaborated in solving the installation of their gas injection valve in the engine. An important part of the solution came from Expanite – a surface hardening technology that makes stainless steel extremely wear and corrosion resistant.\r\n\r\n \r\n

Improved scratch and corrosion resistance<\/strong><\/em><\/h2>\r\n Per Brandt, manager at MAN Energy Solutions, says: \u201cOriginally, 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. 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.<\/em>\r\n\r\n 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 and in addition the solution was also easy and cost efficient to implement.\u00a0\u00bb<\/em>\r\n\r\n \r\n

A cheaper and greener solution<\/strong><\/em><\/h2>\r\n Expanite is a Danish growth company established in 2010 by three experts in materials and surface hardening from the Technical University of Denmark. In short, the technology is a gas-based treatment of the surface of stainless steel or titanium, so that corrosion resistance is improved, and the hardness is multiplied (eg up to 1200HV 0.05 in stainless steel). This eliminates wear and galling, and the lifespan of the parts is increased by a factor of ten. \u00ab\u00a0Expanite’s processes are significantly more environmentally friendly and sustainable as opposed to chrome baths,\u00a0\u00bb<\/em> Claus L\u00f8ndal, European Sales Director in Expanite, emphasizes. \u00ab\u00a0With Expanite, we have the opportunity to change the rules and extend the limits for what qualities you can expect from stainless steel. In addition, our solutions have the advantage that the equipment and processes can be easily implemented directly by our customers.\u00a0\u00bb<\/em>\r\n\r\n \r\n

Hardening of vital components will increase<\/strong><\/em><\/h2>\r\n It is expected to be a huge international market for Expanite, which technology is protected by patents. Expanite has already established service centers in Denmark, Germany, the US and China, and customers are today coming from automotive, medical, food and pumps & valves industry, but the demand for more resistant and durable stainless steel products is wide – also in the marine sector. \u00ab\u00a0We have had a very positive beginning with Expanite, and as the equipment is to deliver more and more and is pushed to the limits, the need for extra hardening of vital components will also increase,\u00a0\u00bb Per Brandt adds\r\n\r\n
