We need to procure SA312 TP 321 100 NB pipes. Customer asks for melting in electric furnace/vacuum furnace & refining by ESR/VAR. Quantum of material is miniature so we can not approach mill . We have to procure material from stockiest, test it & use if meets specification. Now we got TEST CERIFICATE from stockiest which doesn't mention about ESR/VAR.
Is there any way by which we can verify that material is refined by ESR/VAR. Pl. note that impurities like Sulphur, Phosphorus are meeting code limits of chemical composition.
