How does Forging Affect Grain Structure?
The important impliion about grain flow is that some mechanical properties vary with respect to orientation relative to grain flow. This fact is one of the major advantages of forging . This variation in mechanical properties can be exploited so that the actual product has superior properties in a critical direction relative to those expected from the alloy composition itself.

Why is Stainless Steel Corrosion Resistant? - Industrial …
Stainless steel is known for its corrosion resistance in many environments in which carbon and low alloy tool steels would corrode. The corrosion resistance is a result of a very thin (about 5 nanometers) oxide layer on the steel’s surface. This oxide layer is referred
