Stainless spring washers according to DIN 21 June 2016

Lesjöfors AB has launched a new range of Belleville spring washers according to DIN 6796, designed to work under high loads.

Available from Lesjöfors standard stock, the new stainless steel range includes six dimensions from 4mm – 12mm. The washers are made from EN 1.4568 (X 7 CrNiAl 17-7 / SS 2388) instead of regular stainless spring steel for better fatigue properties, and resistance to high operating temperature up to 350ºC. This material also enables spring properties to be retained for a longer time.
Lesjöfors says the new range is suitable for different types of threaded connections where long service intervals are required. Featuring excellent spring properties, as well as good corrosion resistance and fatigue properties, the washers are also suitable for use in demanding applications.
“Lesjöfors engineers have done a very good job with the development of this new range, which we anticipate will be used in many applications to come. Some possible areas of use are in the manufacture of trains, turbines, power plants and industrial machinery,” explains Mårten Glas, managing director at Lesjöfors Gas & Stock Springs.
