Sandvik supplies steam chests produced by powder metallurgically based hot isostatic pressing (PM HIP). The steam chest is a cylindrical part of a turbine with extremely complex geometry including internal cavities.
The conventional way of producing this type of component is to cast, forge, machine, weld and machine again, with the risk of having porosity or segregated parts in the center of the product.
Reduced machining costs
The PM HIP technology makes it possible to achieve equal properties in all parts of the product, almost independently of the product size. It also avoids excessive and costly material loss resulting from machining. By designing the can close to the finished size, including internal cavities, the machining cost of the part is kept to a minimum.
