Yes, Grade 80 chain is significantly stronger than Grade 70 chain, made from alloy steel for higher tensile strength, making it suitable for heavy lifting and rigging, whereas Grade 70 (carbon steel) is primarily for transport and cargo tie-downs, not overhead lifting. The "80" indicates 800 N/mm² ultimate strength, while G70 is 700 N/mm², meaning G80 handles higher loads and stresses.
The biggest difference between grades of chain is that carbon steel chain—Grade 30, 43, and 70—is not recommended for overhead lifting, while alloy steel chain—Grade 80, 100, and 120—is recommended for use in sling assemblies and overhead lifting applications.
Grade 100 chains are the strongest among readily available chains. Their strength-to-weight ratio is about 25% higher than grade 80 chains'. Most of the time, a grade 80 will suffice. However, you may need a grade 100 if the chain's application is heavily concerned with the strength-to-weight ratio.
Inside Width: 0.57 in. Working Load Limit: 7,100 lbs. Weight (per ft.): 1.44 lbs. A higher strength heat treated alloy steel chain primarily used as a sling component for overhead lifting.
Are Grade 80 lifting chains safe to use for heavy lifting? Yes, Grade 80 chains are safe when used within their rated capacity. They are proof-tested, certified, and meet industry standards. Many professionals prefer them because they handle real-world lifting conditions better than the stiffer Grade 100 chains.
What Is the Strongest Necklace Chain Type?
This chain is designed for use as a tie down chain or lashing for transportation. Grade 70 chain has a gold chromate finish to help resist corrosion from continuous exposure to the elements and the rigors of highway use, such as road salts in the winter.
The grade as advertised by chain manufacturers is 1/10 of the actual ultimate strength, which means Grade 70 chain has an ultimate breaking strength of 700 N/mm (or 101,526 psi). Based on this, it makes sense that higher grade chains are going to be stronger and harder.
When it comes to overhead lifting applications, Grade 100 alloy chain is the top choice. Designed for superior strength, durability, and fatigue resistance, this high-performance lifting chain exceeds OSHA and ASME B30.
Thicker chains are sturdier and more durable compared to thinner chains that may break more easily. Thickness between 6-12mm offers a good amount of strength to the chain and also showcases its intricate design, while chains below 2mm may break more easily.
The Grade 80 standard for chain slings has a high strength-to-weight ratio – and is suitable for industrial applications that involve towing and recovery. Grade 80 standard is also commonly used for securing high-duty industrial loads in the flatbed trucking industry.
You can purchase grade 80 alloy chains in 9/32″ to 1″ diameters with a minimum breaking load of 190,800 lbs. and a maximum working load limit of up to 47,700 lbs. Each diameter is also available to be purchased in drums.
46,47,51,80 or 82 = 3/8 pitch .050 gauge. 42,48,54 or 81 = 3/8 pitch .058 gauge. 45,50 or 83 = 3/8 pitch .063 gauge. 69 = .404 pitch .058 gauge. 57,64 or 65 = 404 pitch .063 gauge.
Grade 80 (T) chain is designed for chain slings for industrial lifting applications. It is made from hardened and tempered alloy steel. It has a high resistance to impact and meets critical requirements of AS2321 “short link chain for lifting purposes”.
What's the strength difference between Grade 70 and 80? 3/8” Grade 70 has a working load of 6,600 Lbs with a 4:1 safety factor. 3/8” Grade 80 has a working load of 7,100 Lbs with a 4:1 safety factor. Yep, just a 7% gain in strength going from Grade 70 to 80.
Can I wear stainless steel jewellery to the beach, pool & in the shower? Yes, stainless steel is incredibly durable and waterproof. Unlike silver, it can't oxidise so it is safe to wear in the ocean, pool and shower.
Minimum Break Strength: 26,400 lbs. Working Load Limit: 8,800 lbs.
The case hardened security chain is hardened to 63 rc at 10% depth and 50 rc in the core, making it impossible to cut with bolt cutters or any other hand tool. No other chain on the market is made of stronger materials or has a more difficult design for criminals to defeat.
Cuban link chain is a type of jewellery chain characterized by interlocking, uniform, and oval links that create a thick, rope-like appearance. It is derived from the classic curb chain.
What chain style is strongest? Cuban link, Franco, and box chains are considered some of the strongest chain types. These styles feature tight links and dense structures that resist breakage and wear.
