So, how does the F844 washer compare to domestic washers of the same grade? Like 100HV 140HV
ASTM F844 refers to standard carbon steel flat washers, which are equivalent to the Q235 steel specified in national standards. Domestic washer grades such as 100HV and 140HV refer to hardness levels; HV100 corresponds to softer steel, while HV140 indicates a higher degree of hardness. Therefore, if F844 is to be used as a reference, domestic Q235 gaskets with a similar hardness can be chosen. .
