TYPES OF CHAIN GRADES
Industrial chains consist of linked segments of durable metal, such as stainless steel, galvanized steel, and brass. They are available in a wide range of sizes and strengths to lift and transport materials across a diverse set of applications.

The tensile strength of the base material—i.e., the ultimate breaking strength—determines the rating and grade given to the particular chain. The greater the breaking strength, the higher the grade, and vice versa. The grade indicated for a chain helps industry professionals identify the types of applications for which it is appropriate. For example, the strength of galvanized chains relies on the amount of carbon present in the metal as grade 30 chain has less carbon, it is weaker than grade 40 chain and suitable for service duty applications rather than heavy-duty applications.

Dry G80 chain, which has a high percentage of 97% iron in its alloy composition, is one of the most widely used grades of steel chain. This grade is produced from steel chain with medium carbon percentage, but its mechanical characteristics have been improved by performing a precise heat treatment. This heat hardening process causes higher continuity and, as a result, higher abrasion and tensile resistance in the chain steel crystals. The most commonly used size of this grade of chains is 6 mm to 24 mm, which is used in the manufacture of chain slings and also lifting connections. G80 grade chain must be produced and manufactured according to DIN 818 standard. G80 grade chain is available in polished type, black steel color, hot galvanized, cold galvanized, PVC coated, or plastic, etc. The lowest safety factor f:s of G80 chain should be 4 times its SWL and its Proof Test is 2.5 times SWL.
G80 grade chains are produced through forging operations and are made by cutting steel wires and then welding the points of connection of the grains of this chain. The contro

Industrial Stainless Steel Chain
