There are typically production sampling plans to insure that whatever remains in their explanation control along the means. Most foundries will certainly have the means of screening steel samples directly for H2 web content and that would be done before any mechanical testing. There still is worth to going to the initiative of tensile screening or sprucing up and sectioning if absolutely nothing more as a means of verifying you can manage the uniformity of your mold and mildew media, heating system tune, and regarding making use of scrap steel, I 'd say forget that unless you have an extremely reliable source of details regarding the don't think all wheels are 356, because that is not always so.
