Appropriate conversion of hardness 304L
Appropriate conversion of hardness 304L
(OP)
Is ASTM E140 Table 3 (high nickel alloy) the appropriate table for converting microhardness to Rockwell for 304L stainless steel?

RE: Appropriate conversion of hardness 304L
Or has it been worked to some higher hardness?
And what scales are you trying to convert between?

I have never found the tables to be great for that, but you could use the Ni alloy table in a pinch.
I had better luck converting from Superficial Rockwell scales.
For annealed material it is tougher because you usually can't use Superficial Rockwell.
Isn't there a table marked Austenitic Steels? That might be closer for annealed products.

I will not accept conversion (ASTM E140) from microhardness to macrohardness. If I must do it I will use a reference block of similar composition in a similar condition.
