Chromium (Cr) increases toughness and wear resistance of steel. It improves the tendency of stain-resistance and corrosion. In fact, 14% chromium or higher puts steel in the stainless category. read more

The turbine is always located after combustion chamber and the temperature which the first stage of turbine blades is able to resist is a proof of high technology engine. Those blades are exposed over to 2000ºC; the melting point of steel is around 1100ºC, and nickel can go much further up to 1700ºC. read more

In Kaplan, propeller or Pelton units, the area of greatest concern is the hub or blade flange. Solutions to the material selection concerns. There are three primary solutions to concerns regarding material selection when specifying manufacture of new or replacement turbine runners for hydroelectric projects. read more
