Hydrogen Embrittlement Testing
Hydrogen Embrittlement Testing is preformed in accordance with ASTM-F-519. CMS does sell these speciallized test bars in a set of five. Typical processing involves plating 4 of the sample, the last sample is unplated but still subjected to the relief process. Typical relief process is 350F for 3 hours. The unplated sample is tensile tested for ultimate strength. The four plated samples are held at 75% of the strength recorded on the tensile tested sample. The samples are held for 200 hours in order to certify relief process has difussed hydrogen from structure.
