#80 Chain For Lifting Vs Environmental Resistance

Among professional #80 Chain Manufacturers, one of the recurring challenges is ensuring that the #80 Chain can deliver reliable performance in environments with elevated temperatures. Heat is often an overlooked factor in industrial design, yet in real operations such as steel processing, glass production, or high-temperature conveyor systems, chains are exposed to continuous thermal stress. At Maigao, we understand these realities and focus our engineering on durability under such conditions.

Why Heat Resistance Is Critical

Now that you are considering different types of industrial roller chains, it’s important to understand why high-temperature performance matters. Steel, the more common material for chains, begins to lose its tensile strength when exposed to elevated heat for long durations. This can cause problems such as:

Accelerated elongation caused by material softening

Premature surface wear due to degraded lubrication

Deformation or cracking if cooling and heating cycles repeat frequently

According to published lifting and rigging standards, Grade 80 chain—commonly used for heavy lifting—retains its structural integrity in environments up to 200–400 °C, depending on heat treatment and protective coatings. This makes it one of the more trusted chain categories in demanding sectors like foundries or hot-rolling mills.

Maigao’s Engineering Approach

Here we are going to show how Maigao, as one of the established #80 Chain Manufacturers, addresses the risks posed by heat exposure with a multi-layered production strategy:

Material Selection – We use carefully chosen alloy steels known for their resistance to thermal weakening. These steels maintain hardness while avoiding brittleness.

Advanced Heat Treatment – Each batch of our #80 Chain undergoes controlled carburizing and quenching processes, tailored to balance toughness with high-temperature performance.

Surface Protection – Options such as nickel plating or specialized oxide coatings are applied to reduce scaling, rust, and oxidation at elevated temperatures.

Lubrication Solutions – We work with lubricants formulated to remain stable in high-heat environments, preventing metal-to-metal contact.

Real-World Applications

To learn more about practical uses, let’s look at industries where the #80 Chain is directly exposed to heat:

Steel mills – Chains drive rollers in hot sections where radiant heat is intense. Maigao chains show reduced elongation, ensuring smoother operation.

Cement plants – Kiln conveyors operate continuously in elevated heat. Our chains maintain service life despite abrasive dust and temperature.

Automotive foundries – Heat-treated parts require material handling under sustained high temperatures. Maigao chains reduce downtime by resisting thermal fatigue.

Maintenance Practices for High-Heat Chains

Even the ideal chain design requires proper handling. Here are guidelines we recommend to customers:

Schedule inspections for discoloration, scaling, or cracking.

Use high-temperature lubricants with appropriate viscosity.

Allow for controlled cooling cycles to avoid thermal shock.

Replace sprockets and chains together to maintain fit and alignment.

By following these practices, customers extend the lifespan of their #80 Chains significantly.

Maigao’s Commitment to Long-Term Reliability

At Maigao, our mission is not only to manufacture #80 Chains but also to provide dependable solutions for industries where performance under stress is critical. By combining metallurgy expertise, precision manufacturing, and practical application insights, we help businesses maintain productivity even in harsh operating environments.

Now that you have a clearer picture of how heat affects chain performance, you can evaluate whether your current equipment needs an upgrade. If your operations involve exposure to high temperatures, Maigao’s #80 Chains are designed to offer both safety and durability.
