Hydrogen cracking of grade T and grade 8 chain and components

This guidance gives advice to users of grade T and grade 8 chain and components on their susceptibility to hydrogen cracking. It is the only publicly available guidance which clearly identifies both the problem and the solution and is aimed at users of grade T and grade 8 chains across a range of sectors (particularly chemical and manufacturing).

Incidents reported to the Health and Safety Executive indicate that grade T and grade 8 chain and components are still being used in corrosive environments, despite advice from manufacturers.
