K417G

Description

Ultra-pure melting technology with a clear understanding of impurity element damage mechanisms. Established thermodynamic and kinetic metallurgical principles for impurity removal in superalloy melts. Developed innovative crucible preparation technology. Aerospace-standard remelt slag reaches Grade Zero. Fewer inclusions, fewer metallurgical defects, superior creep life, and higher casting yield. Impurity control achieves the highest US standard. Creep life improved by 211%, micro-porosity reduced by 90%. Casting yield increased from 59% to 85%.
