PM HIP is a widely applied manufacturing technology to produce thick walled and complex shaped duplex and super duplex stainless steel (DSS and SDSS) components for the petrochemical as well as the oil and gas industry. The PM HIP process offers the advantage of a fine grained microstructure which generates an increased resistance to HISC (Hydrogen Induced Stress Cracking) as well as higher...

Material used for steam piping of power plants is exposed to high temperatures and high pressures over long periods. As a consequence, forged Grade 91 alloy steel is commonly chosen to meet these demands. However, complicated structures such as a valve body need to be machined from large forged blocks. As a result, the machining time is long and the material weight is heavy. Therefore, by...

The exhaust valve spindle is one of the most challenging components in the marine two-stroke diesel engine. It has to withstand high mechanical loads, thermal cycling, surface temperatures beyond 700 $^{\circ}$C, and molten salt induced corrosion.
Powder metallurgy gives the opportunity of improving the component using materials not applicable by welding or forging. Therefore exhaust valve...
