410 stainless

Not as corrosion-resistant as the 18-8 variety but will drill through harder materials than the 18-8 screw. The same hardness gradient rule applies: material drilled should be a minimum of 10-20 rockwell hardness points less than the fastener
Heat Treatment:An ideal method of hardening 410 stainless screws is a bright hardening process,which typically involves a vacuum furnace, Another key factor affecting hardness is the chemistry of the fastener–most elements have maximum values but not minimums.This fact can contribute to hardness variance.
