2. Galvanic series - Wikipedia

   en.wikipedia.org/wiki/Galvanic_series

   The galvanic series (or electropotential series) determines the nobility of metals and semi-metals.When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion.

3. Water turbine - Wikipedia

   en.wikipedia.org/wiki/Water_turbine

   The most common material used in Kaplan Turbine blades are stainless steel alloys (SS). The martensitic stainless steel alloys have high strength that allow thinner sections than standard carbon steel; reduced mass enhances the hydrodynamic flow conditions and efficiency of the water turbine.

4. SAE 316L stainless steel - Wikipedia

   en.wikipedia.org/wiki/SAE_316L_stainless_steel

   SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), up to 2% manganese [ 1 ] , with ...

5. Sandblasting - Wikipedia

   en.wikipedia.org/wiki/Sandblasting

   A wheel machine is a high-power, high-efficiency blasting operation with recyclable abrasive (typically steel or stainless-steel shot, cut wire, grit, or similarly sized pellets). Specialized wheel blast machines propel plastic abrasive in a cryogenic chamber and is usually used for deflashing plastic and rubber components.

6. Heavy metal (elements) - Wikipedia

   en.wikipedia.org/wiki/Heavy_metal_(elements)

   Heavy metals are metallic elements with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context and has been argued should not be used.
