-----Spring Steel blades are corroding
Q. Dear all,
My industry has been using blades made up of spring steel (0.75-0.85% C, 0.5-0.8% Mn, 0.4% max S, 0.4% max P, hardness 45 HRC) for a very long time for scraping purpose; but after changing the formulation of the material being scraped, the scraper blade is getting corroded very fast.
By the way, we manufacture soaps and detergents and including more solid materials like feldspar etc. has led to this increase in corrosion rate.
This has been a real bottle neck for our industry we would be highly obliged if anyone could provide us a solution to this problem.

A. Hi Apoorv. It sounds to me like electroless nickel plating or hard chrome plating these blades would be worthwhile.
Regards,
