Application:
R4S is a grade of mooring chain. It is used to offshore facilities, and marine construction projects. According to different strength, mooring chains can be mainly divided into 5 grades: R3, R3S, R4, R4S, R5. Previously, there is grade ORQ, but it is replaced by grade U3. The minimum diameter of mooring chain is φ30mm, in China, the min.dia. about φ50mm. For Grade R4S, its strength higher than R3, R3S, R4 lower than R5. Tensile strength of this grade greater or equal to 960Mpa.
