- Incorporating Zinc ToughTM Technology.
Zinc-ToughTM Technology
The Zinc-ToughTM Technology HA range of Grade 8 Master Links and Quad Assemblies provide superior protection from Hydrogen embrittlement and stress corrosion cracking - making them perfect for lifting operations in offshore environments.
Hydrogen embrittlement is the process by which metals such as steel become brittle and fracture under stress due to the introduction and subsequent diffusion of hydrogen into the metal - it can also be described as hydrogen assisted stress cracking and is particularly prevalent in the extreme conditions of the offshore environment where corrosion is a consistent threat. William Hackett and McKinnon Chain combined their technical knowledge and worked alongside a wide range of stakeholders, including several major oil and gas operators, to develop Zinc ToughTM Technology.
This unique manufacturing process delivers a master link with the tensile strength requirements to deliver a 5:1 safety factor with a hardness value as low as 34-36 HRC. The DNV charpy impact values are achieved at -40C, making the links ability to withstand a shock load at any operating temperature.
