Outokumpu, a global stainless steel producer, has received a first order for its newly introduced LDX 2404 duplex steel from Börger, a German-based company. Börger will use the stainless steel to build tanks for biogas production. The steel will be manufactured at Outokumpu’s facility in Avesta, Sweden.
The LDX 2404 steel has been chosen by Börger as it is cost-effective and has outstanding mechanical properties. It also has exceptional corrosion resistance. The steel will decrease the plate thickness by approximately 25% and consequently will reduce the total weight. These properties makes the LDX 2404 steel more ideal for building biogas tanks.
The LDX 2404 has been manufactured at the company’s Avesta-based Research Centre. The product was introduced in 2010 end and is part of the duplex series. The duplex steel grade is suitable for application in tanks, pressure vessels and desalination facilities. It has high nitrogen and chrome content and less nickel than traditional steel grades.
The biogas tanks will be constructed using a new method of bolting instead of welding. The benefits of bolted tanks are decrease in thickness and low construction time.
