"Is Nickel Strike allowed before Cadmium plating heat treated bearing steel?"December 15, 2020
Q. Have problems with adhesion of cadmium plating over 52100 steel (1% C, 1.5% Cr). Advice from experts in the field suggest a Nickel strike which yields positive results. Because of the Cr content, can we classify the 52100 as being corrosion resistant and/or passive whereby Nickel striking would be permissible IAW AMS2400 [affil. link to spec at Techstreet] and AMS2401 [affil. link to spec at Techstreet] ? Have run across articles stating that 52100 steel is corrosion resistant.Marc A Pelissier

AMS2400 [affil. link to spec at Techstreet] refers to 'corrosion-resistant steel or similarly passive materials' in allowing a nickel strike.
Depending on who you talk to, 'corrosion resistant' steel has approximately 10.5% or approximately 11% chromium content.
At 1.5% chromium, it might be an uphill battle trying to convince someone that 521200 was a corrosion resistant steel.
