Manufacturer & product notes- Manufacturer: Wuhan Jiangnan Anchor Chain Co., LTD (JNAC), established 1987, specialized in marine anchor chain production and outfitting products.
- Anchor chain types: stud link and studless link — stud link chains offer greater strength and resistance to twisting when stacked.
- Steel grade explanation: graded anchor chain steel divided into M2 (no heat treatment) and M3 (heat treated) where higher grade gives higher tensile strength and may allow reduced link size for same strength.
