How strong is a grade 43 chain?

Grade 43 high test chain is extremely strong and durable as it is made of welded steel and has a maximum working load limit of 20,000 lbs. and a minimum breaking load of 60,600 lbs.

Is Grade 43 chain dot approved?

Grade 43 Chain

This grade's higher strength allows it to accommodate DOT specifications for use as tie-downs in the trucking industry. While it cannot be used in overhead lifting applications like Grade 30 and 40, it is appropriate for securing logging loads for on-road transport and vehicle towing.

What grade chain is strongest?

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.

What is the highest grade lifting chain?

Grade 120 is a high-performance alloy chain that generally characterised by its bright colour and square shape. The ultra-premium high strength chain is designed specifically for the rigorous requirements of overhead lifting and has approximately 50% higher strength compared to Grade 80.

What does Grade 43 chain mean?

Grade 43 chain (G43 of G-4) is designed for use in load binding, towing, logging, and other applications requiring high strength. It is made from carbon steel and is available in bright galvanized or zinc-plated finishes. Grade 43 chain is proof tested and should NOT be used in overhead lifting.

What Are the Different Grades of Chain?

What is the difference between Grade 70 and 43 chain?

Also known as “Transport Chain,” Grade 70 chain is most commonly used for tie down and load securement applications for trucking and other cargo. While Grade 30 and 43 chain can also be used for load securement, Grade 70 chain provides a stronger, more durable option with a much higher strength-to-weight ratio.

What is the difference between Grade 43 and Grade 70?

Grade 70. Made from a higher strength, heat-treated carbon steel that has a load rating approximately 20 percent higher than Grade 43. The gold chromate finish makes it easy for DOT officials to recognize. Typically used by truckers, loggers, and highway crews for load securement and towing.

How much strength does it take to break chains?

Minimum Ultimate Tensile Strength: For single-strand chain, equal to or greater than 12,500 × (pitch in inches)2 pounds. The minimum tensile strength or breaking strength of a multiple-strand chain is equal to that of a single-strand chain multiplied by the number of strands.

Is Grade 43 chain good?

Carbon steel chains, like Grade 30, 43, and 70, cannot handle the stress/Newtons required for tasks such as overhead lifting. Meanwhile, alloy steel chains – like Grade 80 and higher – can handle that kind of tensile force and thus are recommended for any heavy-duty lifting.

What is grade 40 chain?

High Test Grade 40 offers higher strength and greater resistance to wear, creating working load limits that exceed those of general utility steel chain. High Test is primarily used in agriculture and construction where greater working loads are experienced. Available in hot galvanized or self-colored finishes.

What grade is trucker chain?

Grade 70 chain was specifically designed for the transportation industry. Grade 70 Chain typically has a 20% higher working load limit than High Test Chain or Grade 43 Chain. G70 chains are also referred to as Transport Chain, System 7, or Spectrum 7.

How do I tell what grade my chain is?

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!

What is grade 50 chain?

Grade 50 is the only stainless steel chain rated for overhead lifting and will resist pitting and most kinds of corrosion. Type 316L stainless steel. Never exceed working load limits, which are based on gradual pull & not shock loads.

Which grade is better 43 and 53?

53 grade cement offers higher strength and durability compared to 43 grade cement. It is suitable for structural projects that require greater load-bearing capacity, such as bridges, high-rise buildings, heavy infrastructure and industrial construction.

What is the difference between grade 33 and grade 43?

Recommended Use: 43-grade cement is widely used in various construction projects where moderate to high strength is required. It is suitable for residential buildings, commercial structures, and other applications where a higher strength is desired compared to 33-grade cement.

Which is stronger grade 70 or 80?

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.

Which grade chain is hardest to cut?

Grades 70, 80, and 100 are among the hardest and toughest available. Here's the kicker, though. We're talking chain that costs $10 to $22 per foot; it's likely to be more valuable than what you're chaining down, a fact that might not be lost on an enterprising thief, who might just make off with the chain itself!

What is grade 43 steel?

Grade 43 is an old number for structural steel acc. BS. It is now called S275. Tensile strength 410-560 Mpa. Yield 275 Mpa (for tk up to 16mm)

What is grade 100 chain?

Grade 100 Chain is a Premium quality high strength alloy steel. Grade 100 Chain has a 20 percent increase in working load limit as compared to a similar size chain in Grade 80. This allows you to reduce the size of the chain depending on the working load needed.

What is the strongest material for chains?

Silver, gold, steel, and titanium are the strongest materials that can last a very long time when properly taken care of. If you're looking for a necklace that will withstand the test of time, one of these materials is your best bet.

What size chain do I need to tie down my tractor?

Typically, grade 70 chain is the standard for tie down chain. Other chain grades such as 80, 100, and 120 can also be used, but aren't as popular.
