Q: Isaw on the website that you produce Belleville spring washers. Are you also able to produce these in TZM? We are looking for Belleville spring washers which can withstand high temperatures to 500 degrees Celsius.
A: Unfortunately, we can’t produce Belleville washers in TZM or other refractory metals,but we can produce them in Inconel. Inconel 600 and 625 offer excellent high temperature resistance to close to 1000°C. In addition, Inconel washers are highly corrosion resistant to many acids including sulfuric and hydrochloric acid.
