Lifting chains are typically made of medium to high carbon alloy steel or carbon structural steel to ensure good hardenability and quenching properties. These include: - 20Mn2, 20MnV: Commonly used for carburizing and quenching chains. - 25MnV, 23MnNiMoCr54: High-strength alloy steels with good hardenability. - 55SiMn, 60Si2Mn: Silicon manganese spring steels with high strength and good elasticity. - 65Mn: Manganese steel with relatively good hardenability.
