Spirol Industries is expanding its range of Disc Springs with the addition of new stainless steel versions. Although stainless steel is not part of the DIN 2093 standard, all the disc springs produced by Spirol are said to be controlled to that exacting level.
Two types of stainless steel disc springs are now available. The new austenitic stainless steel version, X10CrNi18-8 (1.4310), is suitable for low-cycle applications and is available as a standard product. For high-cycle applications, Spirol now also offers precipitation hardened X7CrNiAl17-7 (1.4568) disc springs to special customer order. Both types have excellent corrosion resistance.
Disc springs (often referred to as Belleville washers) are conically shaped, washer-type components that are designed to be axially loaded. They can be continuously or intermittently statically loaded as well as dynamically subjected to continuous load cycling. They can be used singularly or in multiples - stacked parallel, in series or in combination.
