Forged Alloy Steel And Carbon Steel Ring can be manufactured as per customers' drawings. And our technologists also can design the drawings for customers.
Quality first is our principle. Our national level II lab can control the quality chemical composition inspection, mechanical properties inspection,hardness inspection.
Product Introduction
Our forged alloy steel and carbon steel rings are engineered to meet precise customer specifications, as we are fully equipped to manufacture them in strict accordance with your technical drawings. Additionally, to provide comprehensive support throughout the design and development process, our experienced technical team offers customized design services, developing drawings tailored to your specific application needs and functional requirements.
Quality is the foundational principle guiding every step of our production process. This commitment is rigorously upheld by our in-house National Level II laboratory, which enables systematic and thorough quality control. Through advanced testing procedures, including detailed chemical composition inspection, precise mechanical properties evaluation, and accurate hardness inspection, we ensure that each ring consistently meets stringent industry standards and delivers exceptional performance, reliability, and longevity.

About Us
In addition, Henan Zhongyuan Heavy Forging Co., Ltd. (HHF) has built an in-depth understanding and rich experience of nearly twenty years in the field of heavy-duty forging by accumulating technical know-how since it was founded in 2006.
The factory's floor space totals about 150 mu (equal to about 100,000 square meters). Besides three extensive open-die forging production lines with 10,000-ton hydraulic presses as core equipment, two state-of-the-art die forging production lines also work, and they are accompanied by large-capacity CNC machining centres, the necessary heat treatment lines, and the top-ranking national class II laboratory. The annual production capacity is up to 50,000 tons of large open-die and dies forgings (including pieces that single weights are over 30 tons).
Approximately 500 people work for the company at the moment, among them, at least 50 people are the R&D team that concentrates on new technologies, materials, and new processes development. The R&D team is composed of senior engineers and technologists.
Among the quality management system supports are numerous certifications, including the American API Q1 standard, API 7-1 licensing for drill stabilizers and drill collars, CSSC system approval, and international recognition for example ISO 9001:2008 and ISO/TS 29001.
For years, the company has been supplying forged parts as the primary material to big companies at home as well as internationally. Different industries such as energy (wind, hydro, and thermal power), mining machines, shipbuilding, and heavy equipment are the company’s customers. Some big Chinese companies like CITIC Heavy Industries, China First Heavy Industries, Taiyuan Heavy Industry, Goldwind, and Envision Energy are the customers, and there are also clients overseas, like Joy Global, Komatsu, and Caterpillar.
Company exportation of these products continues and it goes beyond 20 countries and regions. The major buyers are Germany, the USA, Australia, India, Russia, Brazil, South Africa, South Korea, and Japan.
HHF takes it as its mission to promote the image of Chinese manufacturing, and always follows the quality policy of "strive for perfection, manufacture high-quality machinery, pursue excellence, and create a first-class brand", so that the company's product quality is steadily improved. The main products have become well-known brands of oil drilling tools and large precision forgings.
According to the physical and chemical laboratory construction of National Grade 2 standards, can meet the tensile test, minus 80 degrees Celsius temperature impact, chemical composition analysis,metallographic analysis, non-metallic inclusion analysis,gas content analysis,grain size analysis and nagnetic induction intensity,no magnet magnetic induction gradient and intergranular corrosion test.
Adherence to National Grade 2 Standards is a declaration of our technical seriousness. It means our laboratory environment controls (temperature, humidity, cleanliness), equipment calibration and maintenance, technician training and certification, testing procedures, and data recording/reporting all follow a nationally recognized, auditable framework. This rigor ensures the accuracy, repeatability, and traceability of every test result we produce.
For our global clients, this in-house capability translates into tangible benefits: reduced lead times for quality certification, complete transparency into material properties, collaborative problem-solving based on hard data, and the absolute confidence that comes from knowing their components are validated by a laboratory whose standards are as high as their own. It is this foundational commitment to verified excellence that allows HHF to stand behind its promise of quality, driving performance and building trust in every product we deliver to the global market.
Our Exhibition
AIMEX - Asia Pacific's International Mining Exhibition
We are proud to have participated in AIMEX, Asia Pacific's premier mining exhibition, in 2019. Our team attended the event in Australia, seizing the valuable opportunity to connect with industry leaders, showcase our heavy forging capabilities, and engage in in-depth discussions with numerous customers and partners.
Event Details:
Show: AIMEX 2019
Date: 2019
Location: Sydney, Australia
Our Participation:
While we did not have a dedicated booth that year, our commercial and technical team was actively on the ground. Our visit focused on strengthening relationships with existing partners, exploring new opportunities, and gaining firsthand insights into the latest trends and demands of the Asia-Pacific mining market. The event served as a critical platform for direct engagement with key industry players.
This experience underlines our commitment to the global mining sector and our proactive approach to understanding and serving our customers' needs in one of the world's most important mining regions.
