Summary for pickling and oiling Discussion
Pickling and oiling is the focus keyphrase here, and the thread asks what the process is, why it may be recommended for hot rolled steel before black zinc plating, how to specify it, whether standards exist, and whether it can be tested. The excerpt does not include a technical answer, but it shows the practical concern: a plater suggested pickle-and-oil for hot rolled alloy steel, while the questioner was unsure why cold drawn material might not need it. A later poster, Chris VanHeusden, specifically asks whether an ISO, ANSI, or GM standard exists for pickle and oil of steel. Because no replies are shown, the page mainly documents the need for a basic explanation and a standard designation rather than providing a resolved procedure. The safest takeaway is that the thread is seeking authoritative guidance on the treatment and its specification, not confirming a single accepted standard in the excerpt provided.
Q. I am just beginning to become familiar with finishing processes (electroplate black zinc to be specific). The material I am interested in having plated can be one of the following: hot rolled & heat treated alloy steel, or cold drawn & annealed alloy steel. A plater recommended that I specify a pickle and oil process for the hot rolled material before proceeding with the electroplate zinc.
1. What exactly is involved with the pickle and oil process?
2. Why is it recommended (or necessary) for hot rolled and not cold drawn material?
3. What is the correct designation for specifying this type of treatment? Are there any standards for this process?
4. Can a part be tested to determine whether or not it has undergone this treatment?
I know these may seem like elementary level questions to an experienced plater, but I’ve had difficulty finding a basic explanation of the pickle & oil process and the need for it.
Thanks in advance for your help,

Q. I am wondering if there is a standard out there for pickle and oil of steel. I am trying to find either an ISO or ANSI or GM standard. Thank you.
