An issue with two other specifications, A789 and A790, which reference Table A1.1 in A480 for product analysis tolerances, brought to attention that the tolerance limits for W-containing grades dont address four grades in A240 that have higher W levels (S31266, S32808, S39274, and S44537). A closer look disclosed that Table A1.1 didnt address grades with higher Ni contents or at least one grade (S38815) with higher Si contents. This action adds the product analysis limits for W and Ni that now exist in Table 1 of A484 and adjusts the range of Si contents slightly.
