Durable Valve Castings in Stainless Steel

As a typical high-silicon austenitic stainless steel, the core performance of CF10 stems from its precise composition ratio. 19% chromium, by virtue of its electrochemical passivation property, forms a dense Cr₂O₃ oxide film 5-10nm thick on the surface, resisting corrosion from Cl⁻, SO₄²⁻, etc. 10% nickel forms a stable austenite lattice, enhances the dislocation energy, and enables the material to maintain good toughness at 100-300℃, with an impact absorption energy of 120-150J. The oxide film is strengthened with 3% to 4% silicon elements, forming a self-healing composite passivation layer. Through solid solution strengthening, the yield strength is increased to over 300MPa, achieving a dual breakthrough in corrosion resistance and mechanical properties. ​ The high silicon content is its performance highlight. It not only combines with oxygen to form a SiO₂ protective film, further enhancing oxidation resistance, but also works in synergy with chromium and nickel to optimize mechani…
