Reduction of overall maintenance costs for critical equipment has been the need of the hour with many high temperature applications. The service conditions seen in many high-temperature applications are extremely aggressive. The life for a high-temperature component is often relatively short compared to applications at ‘normal’ temperatures. Replacement of high-temperature components is therefore often necessary during expensive planned maintenance breaks. Unplanned maintenance breaks that are required when a component failure occurs are increasingly costly to implement. Specially designed high temperature grades can increase the service life of many components and improve the overall productivity of the equipment.
