1021M vs 1022
(OP)
For a fastener, is there an advantage to using 1021M or 1022 steel, or are they basically the same material? What does the 'M' suffix signify?

RE: 1021M vs 1022
Alloy Mn conc (mass percent)
----- ----------------------
1021 0.60 to 0.90
1022 0.70 to 1.00
I assume the M means "modified", though that is by no means certain.
It is almost certain that either alloy will provide the same basic properties for a fastener.
