Is grade 70 chain good?
Grade 70. Grade 70 chain is about 20 percent stronger than Grade 43. It is made from a heat-treated carbon steel that is incredibly sturdy and durable. Grade 70 industrial chains typically come in a gold chromate finish for easy identification – as well as protection from abrasion and scratches.
Does grade 70 chain rust?
G70 chains are made from a higher strength, heat-treated carbon steel and have a load rating approximately 20 percent higher than Grade 43. The gold chromate coating offers them more resistance to rust and corrosion. These chains have become the most common grade of chain used on flatbeds.
What is G70 chain rated for?
The G70 designation signifies that a tow chain’s tensile strength is rated at 70. A tow chain may be marked with a 7, 70, or even 700 to signify the G70 grade.
What is the difference between grade 70 and grade 80 chain?
Grade 80, a heat-treated steel chain, differs from Grade 70 in that it’s known for its excellent strength to weight ratio; therefore, it can be safely used for overhead lifting. Additionally, it can be used as a towing, safety, and recovery chain.
Can you cut grade 70 chain with bolt cutters?
The Grade 70, 80 and 100 chains are impossible to cut with a bolt cutter.
How can you tell a 70 grade chain?
Just look for the “L” and then the number after it. Each number following the “L” corresponds with a grade of chain. On grade 70 this can also show that the chains are DOT approved! The “L” represents Laclede and our commitment to high quality chain products.
How do I know if my chain is 70?
Can grade 70 chain be cut?
The short answer is yes, you can get cut-resistant chain. There are also industrial high-strength welded steel chains that are through-hardened. The larger diameters of these chains, especially the 5/8-, ¾-, and 7/8-inch sizes, are extremely difficult to cut due to their girth and hardness.
What type of chain Cannot be cut?
Hexagonal links (or square or trapezoidal) make it impossible for bolt cutters to get a grip. Chain sold by the foot at the local hardware store performs lifting and towing well, but not theft resistance.

What is the hardest chain to cut?
the Pewag chain
By being the toughest chain, we mean the Pewag chain is the hardest chain to cut with bolt cutters. The biggest reason is the hardened steel chain is squared, so it will not allow bolt cutters to cut through it.
What is grade 70 chain?
Grade 70 chains, also known as transport chain or trucker’s chain, are designed as load securement. G70 chains are made from a higher strength, heat-treated carbon steel and have a load rating approximately 20 percent higher than Grade 43.
Which chain grade should I use for towing?
Working Load Limit (WLL) is the maximum weight that you ever want to put on the chain. For most 4x4s doing recovery, you should be using at least 3/8″ Grade 80 Alloy chain. Why? Because 4x4s are heavy! Think about your rig: First, the GVWR is a pretty good indicator of weight for a lot of off roaders.
What is a transport chain?
The electron transport chain is where most of the energy cells need to operate is generated. This “chain” is actually a series of protein complexes and electron carrier molecules within the inner membrane of cell mitochondria, also known as the cell’s powerhouse.
