Need Hard, Inexpensive, Corrosion Resistant Stainless Steel



March 20, 2019

Q. Here we are using stainless steel SS201 in the spin tube drive assemble in laundry machine. We are facing wear damage in the tube surface because of low hardness. So we need an alternate cost effective material with hardness 35-40 Hrc, and it should withstand salt spray of 500 hours. So please suggest a low cost material to satisfy our need.

A. Have you considered a hard coating such as electroless nickel? It has excellent corrosion resistance and its hardness is 48-52 Rc. With an adequate pre-treatment it can be applied over your actual SS parts.
