Advanced Melting Technology & Quality Features
Proprietary Melting Processes
FUSHUN SPECIAL STEEL’s proprietary melting technology enables precise control over alloy chemistry, microstructure, cleanliness, and performance characteristics through two advanced processes:
Electric Furnace + VAR (AOD+VAR)
Vacuum refining delivers exceptional surface finish and creates pure, inclusion-free alloys through controlled atmospheric processing.
Vacuum Induction + VAR (VIM+VAR)
Ensures virtually inclusion-free alloys to meet the most stringent micro-cleanliness requirements for critical applications.
Premium Quality Features
Superior Surface Finish
Specifically engineered for applications demanding extremely fine surface finishes with exceptional uniformity.
