Grade 43

Grade 43 chain is a specific grade of chain commonly used for various applications that require moderate strength and durability. Here are some key characteristics of grade 43 chain:
Material Composition: Grade 43 chain is typically made from low-carbon steel, which provides a balance between strength and affordability. The exact chemical composition may vary slightly depending on the manufacturer.
Strength: Grade 43 chain has a higher working load limit (WLL) or maximum load capacity compared to lower-grade chains such as Grade 30 chain. It is designed to withstand moderate loads and is suitable for applications that require a higher level of strength.
Finish: Grade 43 chain is commonly available in a self-colored or bright finish, without any additional protective coating or galvanization. Regular maintenance is necessary to prevent corrosion and rusting.
Versatility: Grade 43 chain is versatile and can be used in various applications, including towing, logging, and general-purpose lifting and securing. It is often used in transportation, agriculture, and utility industries.
Weldability: Grade 43 chain can be welded using appropriate welding techniques. However, it is important to follow welding guidelines and ensure proper welding procedures to maintain the chain's strength and integrity.
Standard Compliance: Grade 43 chain may conform to industry standards and specifications such as ASTM (American Society for Testing and Materials) or NACM (National Association of Chain Manufacturers). These standards ensure that the chain meets specific quality and performance requirements.
It is worth noting that the specifications and characteristics of grade 43 chain may vary depending on the manufacturer and the specific industry or region. It is recommended to refer to the manufacturer's specifications and guidelines for detailed information on grade 43 chain and its recommended applications.
