HOT DIP GALVANIZING GRADE 10.9 FASTENERS

Components with a tensile strength exceeding 1040Mpa (10.9) may be susceptible to Hydrogen Embrittlement (HE) and/or Stress Corrosion Cracking (SCC).The key element to these phenomena is hydrogen. In the case of HE, hydrogen can be infused into bolt steel during acid cleaning and be trapped by the galvanizing layer. This risk can be eliminated by mechanical cleaning prior to HDG. In the case of SCC hydrogen is induced from localised corrosion (normally white or other rust) at the site of damage to the zinc coating. This combined with tensioning, could trigger SCC at the most stressed areas of the bolt, resulting in a delayed brittle fracture. There are a multitude of possibilities that could cause this, such as the bolt being on the upper hardness limit for 10.9 resulting in a tensile strength exceeding 1170Mpa.Extreme caution should be exercised when ordering, storing and using any grade 10.9 HDG bolt and nut.

factors to consider:• Engineering design. Could a lower strength, larger bolt be used on the project?• Are HDG bolts necessary, or could an alternative corrosion protection be used?• Bolt assemblies should be ordered, not separate components.• A clear work instruction, relative to packaging, storage and use of the bolt assemblies must exist.• Acceptable lubrication, should be used during the assembly of all high strength HDG bolts and nuts.• Torque tools, should be calibrated daily. Lubrication that will be used, as well as environmental factors should be tak-

en into account regularly, to determine the correct torque to be used, to achieve the desired tension.
