In recent years, ZEICIN has quickly established a firm foothold in the highly competitive markets of Japan and Europe. With independently developed technology, exceptional manufacturing processes, and an unwavering commitment to quality. Here are five key secrets behind ZEICIN Steel’s success:
Processes Secret 1: Revolutionized Production Process for HSS and Martensitic Stainless Steel
Steel series adopts the most advanced smelting and refining technologies available to improve the purity and performance of ZEICIN’S high-speed steels (HSS). The core process includes:
EAF + LF + VD + RS ESR
(Electric Arc Furnace + Ladle Furnace + Vacuum Degassing + Rapid Solidification Electro Slag Remelting)
This accommodates succession, withdrawal and universal radial results in a uniform structure of the steel, excellent wear resistance, red hardness, and toughness, outperforming both domestic alternatives and imported materials from Japan and Europe.
Perhaps one of the greatest benefits of ZEICIN HSS:
A smaller percentage of carbides and better dispersion for stronger, harder steel.

Secret 2: Exclusive RS-ESR (Rapid Solidification Electro Slag Remelting) Technology

In China, ZEICIN’S independent innovation RS-ESR is the most advanced metallurgic technology, which provides the following advantages:
Finer Carbide Structure: The rapid solidification process reduces carbide grain size, improving toughness, hardness, and wear resistance.
Reduced Segregation: It refines the carbide network and ensures even alloy element distribution.
This innovative technology is one of the core advantages allowing Zeicin to outperform even top-tier global competitors.
Secret 3: Working Principle and Advantages of RS-ESR
The RS-ESR process relies on rapid cooling and shallow molten pools, which significantly inhibit the growth of carbides:
Fast Cooling Prevents Grain Growth: Carbides solidify before they can grow too large, resulting in a denser and more uniform steel structure.
This leads to extremely high material performance, ideal for demanding applications like aerospace, automotive, toolmaking, and precision engineering.
Secret 4: Improved Steel Ingot Quality and Forging Ratio
ZEICIN then extends steel making further by improving quality of the ingot and internal structure when a forging is made:
Higher Forging Ratio: Enhances internal density and structural integrity.
Smaller, Even Carbide Distribution: Achieves a uniform distribution grade of Level 4, exceeding many imported steel products.
ZEICIIN high speed steel ingots offer the advantageous of superior forgeability and strength, so that the materials is suitable for high precision tooling and machinery.

Secret 5: Premium Raw Materials and Superior Smelting Methods
Unlike many competitors who rely on recycled scrap, Zeicin insists on premium, high-cost raw materials:
High Alloy Element Content: Incorporating W, Cr, Mo, V, Si, Mn, Co, and cold-rolled sheet steel close to pure iron — with low carbon, low impurity, and high purity.
Electric Arc Furnace Advantage: Zeicin uses EAF smelting, which offers greater material purity than Intermediate Frequency Furnace (IFF) processes used by other manufacturers.
This meticulous selection of raw materials, combined with advanced smelting, results in exceptionally pure and high-performance steel.
Spray Forming: The Future of High-Speed Steel

Zeicin also adopts spray forming, a next-generation powder metallurgy technology with key advantages:
No Macrosegregation: Eliminates large-scale segregation of alloy elements for improved consistency.
Superior Microstructure: Finer carbide distribution enhances strength and wear resistance.
Exceptional Strength and Toughness: After heat treatment, properties significantly surpass conventional ESR steel.
Near-Powder Steel Performance: Service life and durability approach powder metallurgy steel levels.
In spray forming, molten metal is atomized into fine droplets, rapidly cooled, and accumulated layer-by-layer to form a dense, high-performance deposit.
Conclusion: Zeicin Steel — Not Just Following the Standard, But Setting It
ZEICIN commitment to technical innovation and quality leadership has made it a trusted name in the high-end steel industry. With exclusive technologies like RS-ESR and spray forming, along with a strict raw material strategy, ZEICIN continues to exceed global expectations.
By constantly pushing the boundaries of Chinese manufacturing quality.
