G70 chains refer to chains that are made from a specific type of steel alloy called Grade 70 steel. These chains are commonly used in the transportation and towing industry, particularly for securing cargo on trucks and trailers. The "G70" designation indicates that the chain is made from a high-strength steel alloy with a specified minimum tensile strength.
Here are some key characteristics and uses of G70 chains:
Material: G70 chains are typically made from a heat-treated carbon steel alloy. This alloy provides the chain with high strength and durability.
Tensile Strength: Grade 70 steel has a minimum tensile strength of 70,000 pounds per square inch (psi). This high tensile strength makes G70 chains suitable for applications where strength and reliability are critical.
Gold Chromate Coating: G70 chains often have a gold chromate coating for corrosion resistance. This coating helps protect the chains from the effects of weather and environmental conditions.
Link Design: G70 chains are designed with specific links that are stamped with the grade, providing a visible indication of the chain's strength.
Transportation and Towing: G70 chains are commonly used in the transportation industry for securing loads on flatbed trailers. They are also used in towing applications, such as securing vehicles during transport.
Hooks and Attachments: G70 chains are typically equipped with hooks and attachments that are designed to meet industry standards for strength and safety. These hooks often have a specific design to prevent accidental detachment.
It's important to note that G70 chains are not suitable for use in overhead lifting applications. For lifting purposes, chains designed and designated for lifting (such as Grade 80 or Grade 100 chains) should be used to ensure safety and compliance with relevant standards and regulations.
