Grade 30 Chain Strength

With galvanized chain it basically boils down to how much carbon is in the steel.

Grade 30 chain strength. Grade 30 is a multipurpose economical chain. Grade 30 chain is embossed using a 3 30 or 300. It is not safe for overhead lifting. Grade is intended to indicate the strength and tolerance of welded steel chains.

To ensure that alloy chain consistently meets this requirement astm requires the use of certain alloying elements in the manufacturing of the steel for alloy steel chain. Grade refers to the tensile strength of the metal. Grade 30 chain is a general purpose carbon steel chain for farm industrial and home applications such as log chain cargo lashing pipeline hanging tailgate guard rail tow and switch chain. Chain coil is a great addition to any shop garage ranch or job site.

The higher the grade the greater the break strength. Grade 30 proof coil chain is a heavy duty high strength welded steel chain. Grade 30 chain is a general purpose chain often used in industrial and agricultural applications. G30 300 newton square millimeter 43 511 pound force per square inch.

Grade 30 is an excellent all purpose commercial quality chain. We also added information on the grade 30 chain and grade 43 chain. Grade 30 is an excellent all purpose commercial quality chain. It can be used for load securement but is of less strength than grade 43 chain.

Grade 30 aka proof coil has less carbon and is good. Grade 30 zinc plated steel proof coil chain grade 30 proof coil chain is a heavy duty grade 30 proof coil chain is a heavy duty high strength welded steel chain. The grade number used by manufacturers is an indicator toward the ultimate break strength of chain. Used in a variety of industries and jobs including light construction agricultural applications and the marine industry.

From securing a load to hauling equipment or machinery this 35 ft. Astm states that alloy chain shall be able to elongate a minimum of 20 before fracture 7 3 5. Other grades are determined by manufacturers. Grades 100 80 70 43 and 30 are specified by the national association of chain manufacturers nacm.

Typical chain uses grade 30. The heavy duty chain comes stored in a convenient bucket for transport or storage. Also known as grade 30 proof coil chain it s used in a variety of industries and jobs including light construction barrier chains and in the marine industry. General purpose economical chain.

It is designed for use in towing binding logging and other applications requiring high strength chain. This grade 30 proof coil chain is ideal for general purpose hauling and binding.
