Iraeta (Jining) High-tech Equipment Technology Co., Ltd. is a wholly-owned subsidiary of Iraeta Energy Equipment Co., Ltd., which was reorganized from the original Qilu Special Steel Group in December 2020.


The history of Iraeta (Jining) Company can be traced back to 1985. It mainly produces high-strength industrial materials, including alloy steel, military steel, tool steel, gear steel, bearing steel, roll steel, stainless steel and more than 300 categories Brands of high-quality special steel forgings and forging products. These products have been used in national key projects such as the National Aerospace Launcher, the Olympic Torch Lifter, the Three Gorges large-scale start gate, the manufacture of large aircraft molds, high-speed EMUs, and large and heavy coal shearers.


At present, the company has formed a complete production and processing system integrating fast forging, precision forging, heat treatment, finishing, and physical and chemical inspection. And it has become a supporting service backbone enterprise in the domestic locomotive, machinery, tooling, automobile, shipbuilding, petrochemical, aerospace, nuclear power, wind power, military and other industries.


Forging products: carbon tool and die steel, alloy tool and die steel, carbon structural steel, alloy structural steel, bearing steel, gear steel, spring steel, stainless steel, heat-resistant steel, high-speed steel, high-temperature alloy, titanium alloy, Non-magnetic drill collar.

Note: The DIN, EN, ASTM, JIS and other standard products can be customized according to requirements.
