Grade 80 lifting chains are mainly used in various lifting operations,
such as factory hoisting, towing, port transportation, power installation lifting
, construction sites, and bridge construction. They are responsible for
bearing loads and lifting cargo.
Its material is usually high-quality alloy steel, commonly 20Mn2
manganese steel. This material has the following advantages:
High strength: It can withstand high tensile forces, ensuring it will not
break easily during lifting operations and thereby guaranteeing
operational safety.
Good wear resistance: After proper treatment, the surface hardness is
relatively high. This results in minimal wear during frequent use and friction
with other components, helping to extend the service life of the chain.
Excellent toughness: It has good toughness and is not easily
deformed under stress. When subjected to impact loads, it can
absorb energy through its own deformation, helping to prevent
sudden fracture.
High temperature resistance: After heat treatment, it offers good
resistance to high temperatures and can operate normally in
certain high-temperature environments, with its performance not
easily affected by temperature changes.
