Closer examination of the holiday area from the coated specimens did not show any sign of corrosion on the exposed steel surface. The exposed holiday surface was fully protected and appeared unaffected due to immersion in the test solution, except that the machined surface had lost its glossy appearance due to a thin film build-up on the exposed steel surface. (W 262) (1)

Test solution = Solução de teste

The bulk 316 alloy shows the expected behaviour for this alloy in a chloride solution. (W 422) (2)

Chloride solution = Solução de cloreto

Loss of strength can occur as a consequence of fusion welding. The properties of the welded joint will be very dependent on the condition of the material (as cast, annealed, work hardened, solid solution hardened, precipitation hardened) before welding. (W 238) (3)

Solid solution = Solução sólida
