Hot Rolled Steel Coil Rust Prevention Tests - Elsmar Cove

We process Hot Rolled steel coils for many different uses and applications. One common practice is pickling of the coil to clean the steel of hot roll scale and dirt. Some customers request that the steel be oiled after pickling to prevent surface rust.

We are looking at using a different pickling oil as rust prevention and have had some good preliminary trials using a hand application as a means to compare the shelf lives of the current oil vs. the new oil. I'd like to see what kind of results the 2 oils would get in a salt spray cabinet, but it has been years since I've been around these types of test environments and specs. I recall a FORD specification that was for Phos & Oil coating on steel when I dealt with Metal Stampings but can't recall the specification number or the performance criteria for it. I believe the pass/fail criteria was either 24 or 48 hours in a salt spray cabinet with no red rust.

Would there be anyone out there in the Cove who can help me connect these dots or suggest other possible alternatives that we could test these items to?

Thanks in advance for any help.

Keep in mind that the criteria you've cited (24-48 hours) is purely outside the scope of the two standards cited by rsimano. As an example, ASTM B117-11 only prescribes a method - it does not tell you how long you should test for or how to interpret the results, and makes a point of explicitly stating this in the text (See sec. 1.2 and 3.2).
