![]() Three conditions must be met in sufficient amount over a period of time for failure to result. Hydrogen Embrittlement requires three conditions to occur: (1) Material Susceptibility (2) Tensile Stress (3) Hydrogen. To install, choose optional mounting hardware: standard J-bolts or Dent breakaway compliant bolts. Hydrogen Embrittlement (HE) causes permanent loss of ductility in a metal or alloy over a period of time and can lead to catastrophic failures. 3' diameter smooth lamp post, 3-bolt surface mount, includes 2' x 4' electrical access door, black finish. Business Opportunity with DLA Land & Maritime.Introduction to the Clean Hardware Abatement Project.Dent Breakaway Industries is a international breakaway bolt. The Defense Logistics Agency (DLA) included presentations on the transition away from Hexavalent Chromium and Cadmium plating. If you are looking for a breakaway bolt retailer in Buckeye, AZ we have great news for you. On June 2022, Industrial Fasteners Institute (IFI) hosted a webinar on Hexavalent Chromium and Cadmium Abatement. Hexavalent Chromium and Cadmium Abatement LHE Zn-Ni has superior corrosion protection and coating integrity over a wider range of thicknesses. Range of Coating Effectiveness for LHE Zn-Ni vs LHE Cadmium. It recommended updating NAS (National Aerospace Standards) fastener specifications so that LHE Zn-Ni coated fasteners could be made available to the The report concluded that LHE Zn-Ni plating was an upgrade over cadmium hexavalent chromium plated fasteners. Zn-Ni fasteners showed better results for maximum run-on and breakaway torque.Established fastener torque values would not need to be changed for LHE Zn-Ni.Mechanical and corrosion performance was better for LHE Zn-Ni.Eze-Erect Franklin Industries Sign Post System, breakaway, u-channel post system. (by The Triplex Group) -directional, breakaway bolt, 5 different diameters, user specific length. ![]() Testing included Class 1-3 Type II plating. Dent Breakaway Bolt Omin Dent Breakaway Industries, Inc. LHE Zn-Ni Corrosion Testing and Implications for Fasteners. In February 2022, the Ogden Air Logistics Center (USAF) released a report titled breakaway sign and luminaire supports for conformance with current AASHTO specifications. The results were highly positive, with some members stating that LHE Zn-Ni is a drop in replacement for cadmium in high strength steel landing gear ![]() The Zn-Ni compositions considered were from 5-15%, and brighteners and other additives were removed to make the plating porous (dull).īoeing reported positive results with plans for future testing.įurther testing was conducted reported in 2011 in collaboration with ES3, Boeing, and USAF. In 2003, Boeing began work to develop a LHE (Low Hydrogen Embrittlement) Zn-Ni Plating as an environmental alternative to cadmium. Helps Prevent Wind Failures At Fuse Plate As Existing Products Now Experience. Zinc plating has been considered as an alternative, but its performance characteristics are below cadmium plating. Omni-Directional for Breakaway Sign Posts. The military and aerospace community has been in search of an alternative to cadmium plating since the 1970s.ĭue to the industry's need for a stringently tested safe drop-in replacement, progress has been slow. Unfortunately, cadmium plating is still commonly used in military and aerospace applications, including fasteners. RoHS and REACH lists cadmium as a restricted substance (100 ppm) and known human Suggested replacements have included trivalent Hexavalent chromium is carcinogenic and is restricted under RoHS and REACH Historically fasteners used in the aerospace industry have been cadmium plated with hexavalent chromium due to its excellent corrosion resistance, low thickness, and freedom from stick-slip.
