    HEYE Special Steel Co., Ltd is the first to achieve industrialization in domestic.Spray forming technology is atomizing the molten metal or alloy in an inert atmosphere into small solid, semi-solid or liquid melt jet, then spraying directly onto the cold substrate surface, droplet deposition on the surface adhesion, accumulation, spreading, fusion, consolidation and the formation of deposited blank. Because of inert gas atomization and droplet deposition rapid solidification, the billets is with low oxygen content, the high density, homogeneous and fine microstructure, and the carbide distribution of the large cross section  steel bar has been improved greatly.

    Spray steel product advantages : 1) cost-effective, performance meets or exceeds the powder steel , the price is much lower than steel powder ; 2) suitable for multi- variety, small batch-production, high-quality, fast delivery.3) green .
