Extended temperature range for usage of Nord-Lock steel washers
We are glad to inform that our steel washers have now been approved for temperatures down to -50°C. Nord-Lock washers have for long time been used in cold climate applications and now we have obtained official tests results specifying the lower limit of the temperature range.
The Swedish independent test institute Swerea Kimab has, after extended testing, concluded that mechanical properties of the Nord-Lock steel washers are the same at -50°C as at room temperature.
The performance of our steel washers at low temperatures has also been verified by TÜV according to DEF STAN 00-35 Part 3, Issue 4, which is a vibration test at temperatures down to -46°C (-50°F).
