Jiangyin Eternal Heavy Industry Co., Ltd. was established in 2008 and is recognized as a National High-Tech Enterprise and an Innovative Small and Medium-Sized Enterprise. The company specializes in manufacturing special steel forgings ,with products exported to over 80 countries and regions including the EU, the United States, Russia, South Africa, Mexico, Brazil, Chile, South Korea, Vietnam, Indonesia, and the Middle East.
Our special steel forgings are categorized by material into alloy steel forgings, mold/die steel forgings, and stainless steel forgings. By shape, we produce forging shafts, forging rolls, forging rings, forging sleeves, forging plates, and forged round bars. Our products are widely applied in petroleum machinery, engineering and mining machinery, metallurgical equipment, power equipment, steel mill rolling mills, cement rotary kilns, roll presses, ore crushers, papermaking rolls, and rubber and plastic rollers.
Cold rolling rolls must withstand high rolling pressures, thermal shock, and cyclic stresses, requiring excellent wear resistance, contact fatigue strength, fracture toughness, and thermal shock resistance. Below is a cross-reference of commonly used cold rolling roll steel grades:

The company produces various forging rolls widely used in steel mill rolling mills, copper and aluminum strip rolling mills, and other heavy industrial applications. Our forging process ensures dense internal structure, significantly improving material strength and enabling forged components to withstand larger loads. We have also developed advanced forging techniques such as the composite forging process combining "upsetting WHF method for elongation + upsetting FM method for elongation" to achieve forging looseness and porosity elimination, improving stress and inclusion distribution in the core of steel ingots.
Equipment / Capability | Specification |
|---|---|
Heat treatment furnaces | Tempering and quenching furnaces |
Vertical medium-frequency induction hardening machine | 6-meter |
Straightening press | 500 tons |
CNC lathes | Length range: 2 – 11 meters |
Gantry machining centers | Available |
The company's heat treatment capabilities include normalizing, quenching and tempering, surface quenching, and other thermal processing techniques. The heat treatment furnace, officially put into operation, marked a milestone in the company's technical upgrade, providing strong support for sustainable development and delivering better quality products and service guarantees to customers.
For cold rolling rolls, our heat treatment processes cover spheroidizing annealing (790–810°C), quenching (880–900°C with water, oil, or PAG quenchant cooling), and tempering, achieving surface hardness of 60–65 HRC with effective hardened layer depths of 6–15 mm. For mold steels and stainless steels, we apply tailored heat treatment protocols to achieve optimal combinations of hardness, toughness, and wear resistance according to specific application requirements.
In addition to forging and heat treatment, the company is equipped with comprehensive quality inspection equipment, including tensile testing machines and non-destructive testing (NDT) equipment. Complementary machining capabilities with CNC lathes (2–11 meters) and gantry machining centers enable us to provide finished or semi-finished forged components ready for customer assembly.
With over 20 years of machining experience, rich heat treatment expertise, complete production equipment, and strict quality control from raw material through to final inspection, Jiangyin Eternal Heavy Industry is your trusted partner for high-quality special steel forgings
