Chain conveyors used in wet, corrosive, and heavy-duty applications typically use chain made from which material?

In applications where wet, corrosive, and heavy-duty conditions are present, chain conveyors often utilize manganese steel for several reasons. Manganese steel is known for its exceptional toughness and high resistance to wear and impact, which are crucial for heavy-duty applications where the chain experiences significant mechanical stress.

Additionally, manganese steel exhibits great strength and hardness as well as the ability to work-harden, meaning its surface becomes harder over time under constant stress. This characteristic is particularly beneficial in environments where chains are subjected to heavy loads and abrasive materials, as it prolongs the service life of the chain.

While stainless steel is also resistant to corrosion and is often used in some conveyor applications, it may not possess the same level of toughness and impact resistance as manganese steel, making it less ideal for extremely heavy-duty situations. Plastic composites and aluminum alloys are more suited for lighter applications due to their weight and material limitations under heavy loads and extreme wear conditions. Thus, manganese steel is the preferred choice for chain conveyors in tough environments.
