Influence of Final Tempering Temperature on Side-Grooved Super-High Energy Charpy Specimens of 9310 Steel (Second Phase)
During Fiscal Year (FY) 2022, a study was conducted at NIST to identify the optimal combination of heat treatment (specifically, final tempering temperature) and side-groove depth for super high energy reference Charpy specimens of 9310 steel. During FY23, a second phase of this investigation took place, wherein two additional values of the final tempering temperature were tested, while keeping the side-groove depth at the value previously established (0.9 mm/side, corresponding to 18 % of the original thickness). In consideration of the overall activities performed, final recommendations concerning the final tempering temperature and the side-groove depth are formulated for future NIST reference specimens of super-high energy level, manufactured from 9310 steel.
