MST Corp (USA) provide manufacturing and services for critical machinery and parts used in the manufacture of pulp and paper, paper recycling and related continuous process industries. This typically involves the replacement or re-design of large capital parts that are not available ex-stock, and therefore require a more flexible approach to re-manufacture and selection of materials.
The above part highlights a common application for Ferralium® 255, agitator blades, that benefit from the exceptional erosion corrosion resistance of this metal – superior to most other metals. The image shows the original (OEM) parts on the left-hand side, supplied in Alloy 316 stainless steel, which would often be seen as a reasonably high-performance choice of material. However, in this case, the replacement frequency was much shorter than anticipated. When fabricating replacement parts, MST specified Ferralium® 255, which had given more than twice the operational lifetime at the time of writing. Although there is a difference in raw material costs for the agitator blades, the benefit of extended operating cycles and availability far outweighs this. Ferralium® 255 is able to provide the lowest ‘total cost of ownership’ for many applications through its combination of performance, cost and ready availability.
