Method for producing a bellows and / or bellows |
| abstract |
The invention relates to a method for producing a bellows austenitic stainless steel with increased compressive and fatigue strength, wherein a single or multi-layer sleeve is formed by hydraulic deformation to a bellows. To improve in particular the pressure resistance and fatigue strength is provided that the bellows is cleaned after the forming and that subsequently the bellows an environment with carbon and / or nitrogen atoms at temperatures between 100 ° C and 400 ° C, preferably 200 ° C to 320 ° C is exposed, whereby by diffusing carbon and / or nitrogen atoms hardening of the bellows takes place. A bladder made of austenitic stainless steel with one or more layers thus produced is characterized in that the surface layer is hardened to a depth of hardening of at least 5% of the wall thickness by incorporation of carbon and / or nitrogen atoms. |
