In industries where strength and reliability are paramount, G80 link chains have become a staple for heavy-duty applications. Whether used in construction, lifting, or marine operations, these chains provide the necessary durability to withstand challenging environments. When it comes to purchasing G80 link chains, understanding the specifications, materials, procurement channels, and price factors is essential for making an informed decision. This guide will explore these critical aspects of buying G80 link chains to ensure that businesses get the best quality and value.
Grade 80 High Test Welded Steel Chain is a type of chain that is made from high-quality steel and is specifically designed for use in heavy-duty applications where high strength and durability are required.
The "grade 80" designation refers to the minimum breaking strength of the chain, which is 80.000 pounds per square inch (PSI). This means that the chain is capable of supporting heavy loads without breaking or deforming under stress.
The "high test" designation indicates that the chain has undergone a specific heat treatment process that increases its strength and toughness. This process involves heating the steel to a high temperature and then quenching it in water or oil to harden the metal.
