Alloy steel chain
Alloy steel chain is often used because of their strength, durability, abrasion resistance and ability to conform to the shape of the loads on which they are used. In addition, these slings are able to lift hot materials.
Grade 80 heat-treated alloy steel chain for applications such as slings, lifting assemblies, and load binding. Alloy steel chain is made by the electric welding or gas welding process. The material shall be heat treated which includes quenching and tempering. Material’s composition shall conform to the chemical requirements for carbon, phosphorous, sulfur, nickel, chromium, and molybdenum. The material shall conform to the mechanical property requirements for breaking force and elongation and to the dimensional requirements for the appropriate size chain. All chain shall be tested to at least the proof load.

Grade 30 chain comes with a zinc plating to offer some corrosion resistance. It is a light-duty chain yet is suitable in many applications for general industry,.farming and homeowners.
Grade 43 ( High Test) galvanized chain to offer great corrosion resistance. It is about 50% stronger than Grade 30 chain and is suitable in many applications for general industry, farming and homeowners.
