What is a grade 43?

Grade 43 chain, commonly called High Test, is manufactured to meet ASTM and NACM specifications. Typical uses include container securement, logging, towing, and marine industry. Grade 43 chain is available in many finishes and package configurations. It should not be used for overhead lifting.

Is Grade 43 chain good?

Grade 43 chains are used in more demanding applications. These include towing, construction, and trucking. They're often used interchangeably with grade 30 chains unless an application exceeds the grade 30 chains' working load limit.

Is grade 43 or 70 better?

Grade 70. Made from a higher strength, heat-treated carbon steel that has a load rating approximately 20 percent higher than Grade 43.

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 is the difference between Grade 43 and Grade 70 hooks?

Grade 70 chain is about 20 percent stronger than Grade 43. It is made from 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.

What is a Grade 43 hook?

Grade 43 hooks meet all DOT requirements for use with Grade 43 transport chain, which is widely used for securing loads on flatbed trailers. Slip hooks form a noose which tightens when a load is applied, while the latch ensures that the chain does not inadvertently slip out of the hook.

Which is stronger Grade 70 or grade 80 chains?

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.

How strong is Grade 43 chain?

Grade 43 chain is a steel chain that possess greater tensile strength than Proof Coil Chain. Grade 43 Chain typically has a 50% higher working load limit than Proof Coil or Grade 30 Chain. G43 chains are also referred to as High Test Chain, Grade 40, Spectrum 4 or System 4.

What is the best grade of chain?

About 25% stronger than the chain rating 80, the chain Grade 100 is the strongest chain on most chain suppliers' markets. G100 is made of similar strong, alloy steel and can be used in a variety of jobs and industries including overhead lifting slings, construction, manufacturing, and rigging!

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 GCSE grade 43?

Yes, a 4-3 means just missed a 4-4 on the higher paper. There was no hyphen or anything at all, it was literally written as '43' hence totally baffled! which seems to suggest as per @MrsacksonAvery that this is one old style grade C pass, and one old style D.

What is 43 and 53 grade?

The main difference between 43 and 53 grade cement is its compressive strength. 43 grade cement has a minimum compressive strength of 43 MPa, while 53 grade cement has a higher minimum compressive strength of 53 MPa after 28 days of curing.

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)

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 chain thickness is best?

How can you tell if a chain is 100 grade?

To help identify the grade and manufacturer all of our Grade 80 Chain is embossed with”L10”. The L is the chain manufacturer Laclede. The 10 identifies this as a Grade 100 Chain. On sizes 3/4", 7/8” and 1” grade 100 chain ) it will be embossed with P10 or P100.

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

Can bolt cutters cut grade 70 chain?

This chain is common in the US and can be identified by the term "Grade 70" and the typical gold color. The 5/16" size can BARELY be cut by 36" bolt cutters with a 180lb guy bouncing all his weight on the handle for about 20-30 seconds, including 1 or 2 chain repositions.

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.

What is the strongest chain made?

If you need maximum strength and low cost, then steel is the best option. If you need corrosion resistance and high strength, then stainless steel is the best option. Its as strong as steel but it costs a lot more. If light weight is important, but maximum strength isn't, then aluminum or plastic are good options.
