The company currently owns production equipment such as vacuum melting, electroslag remelting, forging and hot rolling (outsourced), solution treatment, machining, cold drawing, cold rolling (outsourced), and polishing. Our own laboratory can complete the testing of alloy chemical composition, mechanical properties, and flaw detection.

We can independently produce high-performance alloy materials such as nickel-based superalloys, cobalt-based superalloys, precision alloys, and special stainless steels. Products: forgings, billets, coils, bars, slabs/sheets, etc.
