Grade 43 Chain Breaking Strength

Grade 43 chains are also referred to as High Test Chains or Tow Chains. Beaver Grade 80 T Lifting Chain Beaver Grade 80 T Chain manufactured from heat treated alloy steel and is ideal for heavy duty lifting applications.

What Are The Differences In Industrial Chain Grades

National Association of Chain Manufacturers The chain grade is based on the nominal stress in the link at the design breaking force strength.

Grade 43 chain breaking strength. The grade numbers commonly used to denote the strength of chain are numerically one-hundredth or one-tenth of the strength of the wire expressed in megapascals MPa. Grade 43 chain is embossed using a 43 or a G4. 814 Grade 70 chain shall be embossed at least with 7 70 or 700.

It is not rated safe for overhead lifting. Grade 43 has a working load limit ranging between 2600 to 13000 lbs. An excellent choice for ground tackle Grade 43 chain is about 35 stronger than conventional BBB chain which allows you to save weight without sacrificing anchoring security.

All three chain grades can be supplied. In practice by a trifle less than 4. 38 G4 has a working strength of 5400 pounds.

Grade 70 Transport Chain is also called Grade 70 Truckers Chain as its common in securing loads for over-the-road hauling. So a G3 or G30 chain is made from a wire with a minimum breaking strength of 300 megapascals or 300 Newtons per square millimeter. One of the safety measures implemented was to place chain in Grades based on the ultimate breaking strength of that chain.

Grade 43 High Test chain is manufactured from high-carbon steel formed and electrically butt-welded to the shapes and sizes shown. Also called Grade 43 High Test Chain or Grade 43 Tow Chain this is common in the towing and logging industries. 812 516 84 mm and larger Grade 30 chain shall be embossed at least with 3 30 or 300.

This light-weight higher carbon steel chain is significantly stronger than Grade 30 meaning that a lighter chain can often do. 813 Grade 43 chain shall be embossed at least with 4 43 or 430. However it is not approved for overhead lifting applications.

13 44115 43 CHAINS CHAINS GENERAL INFORMATION. Grade 70 is not for overhead lifting. Larger and smaller links are available but these are the three sizes that you will encounter in most marine chandlery stores.

A high-strength light-weight carbon steel chain designed for load binding applications. All other Grade 30 43 70 80 and 100 chains shall be embossed at intervals no greater than 3 ft. 13 The chain grade is based on the nominal stress in the link at the design breaking force strength.

It is used in barrier chains light construction as well as the marine industry. This true high tensile is not the same as high test. Grade 43 chain is the next strongest grade of chain of which can be used for slightly more heavy-duty applications than Grade 30.

516 G4 has a working strength of 3900 pounds. Grade 43 Chain. 123 Grade 70 Transport chain.

This number is what we see today G30 G43 G70 G80 G100 and the common chain grades. P7 GRADE 70 Transport Tie Down or Binding Chain. Chains Grade 80 and above are considered to be ok for overhead lifting.

Doubling the size of a chain theoretically multiplies its strength by 4. These chains are not recommended to be used for overhead lifting. Grade 70 is made with the same 1022 steel as grade 43 high test but it is then heat treated which makes it stronger still.

Medium tensile chain is G4 or G40 tensile strength of 400 MPa. Grade 30 Grade 43 Grade 70 Grade 80 Grade 100 Grade 120 Tie Down Load Securement Printed Wall Charts Available - Call Toll-Free for details 8663922829 or Contact Us. 122 Grade 43 High test chain.

It meets Australian standards AS 2321 Short-Link Chain for Lifting Purposes. It is high strength. Made from a higher strength heat-treated carbon steel that has a load rating approximately 20 percent higher than Grade 43.

Grade 40 High Test Chain. P4 GRADE 43 High Test Chain. The number after each letter is Nmm 2.

It is calculated by taking the minimum breaking force load and dividing by two times the nominal cross sectional area of the link Another words the higher the grade the stronger the chain. High tensile chain is that made of steel with a tensile strength much above 500 MPa. High Test Chain is used in industry mines quarries oil fields lumber camps and by original equipment manufacturers.

And a breaking strength of 16200 pounds. In the United States and some other regions this is commonly branded as high test which is not the same as high tensile. Grade 30 chains possess less carbon and are an effective service duty chain.

This type is also referred to as grade M in Australia. Typically used for container securement logging farming towing marine applications and as general purpose utility chain. All grade 70 from Peerless is stamped P7 on every link.

TESTED AND COMMERCIAL CHAIN. In the hot-dip process this chain is specially shot-peened before galvanizing to create long-lasting protection against corrosion. And a breaking strength of 11700 pounds.
