301 stainless steel half hard 20 guage
by Snowman
(Chicago Il)
Why is it so hard to weld and grind smooth? Using 308 filler rod repairing the panels on the outside of a train. Train body is from Japan.
---------------------------------------------------
301 has more manganese that allows it to work harden.
Same stuff used in abrasion resistant steel.
reminds me of the old saying
"harder than Japanese arithmetic"
