High Resistance marine d-shackles from Petersen Hi-MOD are manufactured in the UK from European material.
The term ‘high-resistance’ refers to the very high strength of the special stainless steel used to manufacture these shackles. The grade is called 17-4PH where the ‘PH’ indicates that the material is heat treated after forging to develop the optimum mechanical properties. This heat treatment is called ‘Precipitation Hardening’ in reference to the way small clusters of ultra strong crystals grow inside the material during the process.
