Applicability and limitations
Official GB/T38809-2020 cover PDF1, PDF5 Table 2 and footnote a/b, heat-analysis mass fractions wt%. ; Product-analysis tolerances follow Table 3 and GB/T222 separately; they are not added to the default heat-analysis range. ; Steel-bar application, steelmaking, delivery condition, specimen heat treatment and mechanical requirements must be confirmed separately; This does not automatically establish a cold-heading product or supply guarantee.
