Grade 80

Grade 80 chain is a high-strength alloy steel chain known for its exceptional strength-to-weight ratio and durability. It is widely used in heavy-duty lifting, rigging, and overhead lifting applications. Here are some key characteristics of grade 80 chain:
Material Composition: Grade 80 chain is made from a special alloy steel that undergoes a heat treatment process, which enhances its strength and toughness. The specific chemical composition may vary depending on the manufacturer, but it typically includes chromium, molybdenum, and other alloying elements.
Strength: Grade 80 chain offers a significantly higher working load limit (WLL) or maximum load capacity compared to lower-grade chains such as Grade 30 or Grade 43. Its high tensile strength allows it to handle heavy loads and provide increased safety and reliability.
Finish: Grade 80 chain is commonly finished with a protective coating, such as a yellow chromate or gold zinc plating, to improve corrosion resistance. This coating helps prevent rust and extends the chain's lifespan, especially when used in outdoor or harsh environments.
Markings: Grade 80 chains are typically marked with "Grade 80" or "G80" along the chain links for easy identification and compliance with industry standards.
Versatility: Grade 80 chains are versatile and find application in various industries, including construction, manufacturing, and transportation. They are commonly used in overhead lifting, slings, towing, and heavy-duty rigging operations.
Standard Compliance: Grade 80 chains are manufactured to meet stringent industry standards, such as ASTM (American Society for Testing and Materials) and NACM (National Association of Chain Manufacturers). These standards ensure that the chain meets specific quality, strength, and performance requirements.
Safety Considerations: It is crucial to handle and use grade 80 chains in accordance with proper safety practices and guidelines. Regular inspections and maintenance are essential to ensure the chain's integrity and performance. Additionally, it is important to ensure that the chain is not overloaded beyond its rated capacity to maintain safety.
Grade 80 chains are preferred in applications that require high strength, durability, and resistance to wear and impact. When selecting grade 80 chains, it is important to consider factors such as load requirements, environmental conditions, and compliance with applicable industry standards to ensure optimal performance and safety.
