Processing Technique

Intermediate frequency furnace smelting high-quality steel scrap and mix chromium based on requirement.

Constant temperature casting process ensuring the quality, no solid nonmetallic impurity, no pore, no mal-roundness etc. Annealing process changing the internal organizational structure, lowering the breakage, and improving the performance.

After the Pre-furnace test, semi-finished products and finished products inspection was done by advanced spectrometer and durometer imported from Germany.
