Benefits Of Forging Stainless Steel
Corrosion Resistance: Stainless steel is naturally corrosion-resistant due to the addition of chromium. The chromium reacts with the atmosphere to create a thin oxide layer on the surface, shielding it from the environment and reducing the risk of stress cracking, deformation, pitting, and other factors that would impact the structural integrity and lifespan of the forged components.
Improved Strength: The forging process creates a continuous grain flow throughout the component, which improves the mechanical properties of stainless steel and increases strength, fatigue resistance, and impact resistance in the forged component.
Improved Heat Resistance: Components designed for high-friction and high-heat applications made from stainless can withstand extreme temperatures without deforming or losing their structural integrity. Specialty stainless grades such as 17-4PH are particularly well-suited to applications that need to resist deformation under such conditions.
