About material hardness
(OP)
Dear Friends ,
i am referring few ASTM standards for material acceptance. so few questions here.
For ASTM A216 material : why does hardness is not given for material acceptance?
Same for ASTM A 182 : Hardness is not given for 316 and F51 Grade.
Same for ASTM B 564 standard : Hardness is not given .
Any specific reason for not giving hardness for acceptance criteria?

RE: About material hardness
Because hardness is not needed for these carbon steel grades. There is no specific heat treatment that requires hardness testing to verify compliance.
Again, not needed for acceptance as above.
Not needed, as above.
