What is Alloy Chain?
Alloy Chain, also known as “alloy steel chain”, is a type of heavy-duty steel chain welded from high-strength alloy steel, known for its exceptional strength and durability. Most alloy chains are suitable for applications with high safety requirements, such as Grade 80 or Grade 100 chains used for overhead lifting. They can also be used as G70 (transport chains) or for fabricating alloy chain slings to facilitate the transportation or bundling of heavy-duty goods.
With over 25 years of experience in alloy chain production, Tuohai possesses multiple patented technologies and advanced production lines. We offer comprehensive customization services, including sizing, materials, surface treatments, etc. Our alloy chains surpass international standards in performance and ensure long-term safety in various applications.

Made from 20Mn2 or 25MnV, this low-carbon alloy steel chain offers high strength and is commonly used as a transport chain.
G80 chains typically use 20Mn2 or 30CrMnTi and undergo heat treatment, resulting in extremely high strength and wear resistance.
G100 chains, made from alloys like 42CrMo or 30CrMnTi, boast higher strength, working loads, and wear resistance compared to G80 chains.
SS304 alloy chain featuring good corrosion resistance and relatively low cost, suitable for light-duty lifting applications.
SS316 alloy chains offer excellent corrosion resistance and mechanical properties, suitable for medium-strength lifting applications.
SS316L chains exhibit higher weldability and corrosion resistance, often used in marine or chemical environments, and food or medical equipment applications.
Alloy Chain By Surface Treatment
Tuohai can provide various surface treatments for Alloy Steel Chains aimed at enhancing their corrosion resistance, wear resistance, aesthetics, or other special functionalities.

The main difference between Alloy Chains and Carbon Steel Chains lies in their material composition.
Alloy chains contain various metallic elements such as Mn, Ni, Cr, etc., which enhance their wear resistance, corrosion resistance, and strength. They are widely used in applications requiring heavy-duty loads and high safety standards, especially in marine environments.
On the other hand, Carbon Steel is composed of iron and carbon. The carbon content determines the strength and toughness of carbon steel chains. However, they generally have lower corrosion resistance and often require additional coatings or anti-corrosion treatments to improve durability.
Alloy Chains can be made from various alloy steels. Some commonly used materials include:
- 20Mn2: Carbon steel alloy primarily used for manufacturing high-strength chains.
- 30Mn2: Carbon steel alloy with good strength and wear resistance.
- 35Mn: Medium carbon manganese steel, used not only for chains but also for various fittings.
- 40Mn: Medium carbon manganese steel with good strength and wear resistance.
- 40Cr: Chromium steel alloy, often used for chains requiring high strength and wear resistance.
- 42CrMo: Chromium-molybdenum alloy steel with excellent strength and toughness, suitable for heavy-duty and high-wear environments.
- 50Mn: Medium carbon manganese steel commonly used for high-strength chains.
- 65Mn: Spring steel with high strength and hardness, suitable for chains requiring elasticity.
- 20CrMnTi: Chromium manganese titanium alloy steel used for wear-resistant and high-strength chains.
- 25MnV: Medium carbon manganese vanadium alloy steel is typically used for chains requiring certain strength and wear resistance.
- Additionally, stainless steel, being an important branch of alloy steel, can also be used for making alloy chains, with grades such as 304 or 316 being common.
The maximum load capacity of Alloy Chain depends on factors such as material, size, grade, and manufacturing processes.
Generally, alloy chains made of 42CrMo material have the highest load capacity for a given size and grade.
However, the load capacity of alloy chains is not solely determined by the material, it also depends on precise chemical composition, heat treatment, and the chain’s structural shape.
We can provide Alloy Chains according to various standards, including European standards such as BS EN 818-2-1996 + A1-2008, BS EN 818-4 1996+A1 2008, and DIN 5687-1-1996, or American standards such as ASME B30.9-2021, among others.
Certainly, we can provide custom alloy chains in various non-standard sizes.
