Have a look at the material specification and the purchase documents for the material that was ordered. The material spec will require some minimum extent of marking, while there are often a number of supplementary requirements that can be invoked and specified on the purchase order.

Your QC Manual should spell out what markings are required to be maintained on material. As far as from the supplier, I would think that the main thing to look for is the material type/grade, and heat number. The p.o. should match material type and size, and the heat number will be traceable to the MTR, where you will find again material type/grade, also chemical composition, and mechanical properties, when required. Again, depends on you manual, but a common recieving inspection practice is to have all paperwork (b.o.m., p.o., m.t.r.) on hand and physically verify all markings/requirements match each other. Hope I explained that o.k.
