HIC

HIC

(OP)
What are the chances of a normal SA516-70N plate passing a NACE HIC test per NACE TM0284.

Please share your experience or thoughts.

Thank You.

RE: HIC

Quite low chance of passing unless the steelmaer takes the propper precautions in ladle practices and casting.

Dear grampi1

Thank you.

RE: HIC

To add to grampi1's comment, again quite low if the purchaser has not included the HIC requirements to the manufacturer.  

RE: HIC

You might want to look at the Tuf 37 plate from American Alloy Steel.   Lukens Steel use to make it for them, but they are gone, and I don't know the mill that supplies them at the present time.   
We use this plate for all our specs that call for HIC materials due to process H2.

RE: HIC

unclesyd,

FYI, the Coatesville, PA steel plate rolling facility that was formerly known as Lukens Steel still exits, it is now part of ArcelorMittal Steel.  Probably the same source for AAS, since there is not much plate rolling capacity in North America.

RE: HIC

You might want to look at NACE MR0175/ISO 15156 Part 2 Clause 8.5 and NACE Report 8X194. Both documents provide some informal guidance on chemistry criteria that might typically be provided by end users to increase the likelihood of the steel being able to pass the HIC tests.

Having said that, as far as NACE MR0175/ISO 15156 is concerned, if HIC resistance is required, then the steel must be tested. It does not allow you to use manufacturing process and chemistry limits as an alternative to testing if HIC resistance is required for your application.
