Semih Metals, Istanbul, Turkey, is a well-known manufacturer and supplier of Titanium Grade 11 forgings, providing high-quality titanium components with improved corrosion resistance in harsh environments. Using advanced forging technology and rigorous quality control, Semih Metals guarantees that every Grade 11 titanium forging meets international standards and customer requirements. Used in industries like chemical processing, marine, power generation, and desalination, the company delivers long-lasting, dependable forgings that offer strength, toughness, and superior resistance to reducing and acidic environments.
Titanium Grade 11 forgings consist of commercially pure titanium alloyed with a small percentage of palladium (0.12–0.25%), which provides extreme resistance to crevice corrosion, pitting, and stress corrosion cracking. Such forgings have tensile strengths of 240 to 350 MPa and yield strengths of approximately 170 MPa, with elongation to 24%. The process improves mechanical properties through grain refinement of the structure, increased toughness without compromising the enhanced corrosion resistance inherent in Grade 11 titanium. It also possesses excellent formability and weldability for complex and critical parts.
