Good stuff, I'm thinking the temperature might be a bit misleading. Dark straw is less than 500 deg (approx 475) as a temper color? Maybe a trick question David?? I would think 4140 would be a good material for those components but you mention corrosion which is why the stainless was mentioned. Corrosion could be from no seals on originals which you are obviously adding to yours..........
