- The maximum load to be lifted by the apparatus;
- The shape of the load to be lifted;
- The size of the sling and leg assembly required to appropriately lift the load;
- The overall length from the link to the hook;
- The associated components such as links and hooks;
Would you use grade 70 chain for lifting purposes?
Carbon Grade 70 chain is a “heat treated” carbon steel chain that has no alloying elements added to the steel. This chain will elongate before breaking but does not have the properties needed for overhead lifting; therefore, Grade 70 chain is not intended for overhead lifting.Feb 20, 2020

Are chains made of stainless steel?
In addition to carbon steel, manufacturers also employ stainless steel to produce chains with greater corrosion resistance. In particular, they often use 304 and 316 stainless steel grades, which exhibit a higher carbon content than other stainless steel alloys and, therefore, higher tensile strength.Mar 10, 2020
What is stainless steel jewelry made of?
Stainless steel contains at least 10% chromium and, depending on the grade of the stainless steel, it may include smaller percentages of nickel, molybdenum, titanium, niobium and other metals.
What kind of metal are chains made of?
Typical materials used are steel, aluminum and brass, although silver, gold or platinum chain is regularly used by jewelers.
How can you tell a 70 grade chain?
Grade 70 industrial chains typically come in a gold chromate finish for easy identification – as well as protection from abrasion and scratches. Grade 70 chain is also usually embossed with a number 7, 70, or 700 on each link. Grade 70 has a working load limitworking load limitWorking Load Limit (WLL) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor (SF).https://en.wikipedia.org › wiki › Working_load_limitWorking load limit - Wikipedia available between 3,150 to 15,800 lbs.Jun 29, 2020
How strong is G70 chain?
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.Jan 20, 2021
