Chemical Composition4.1 The material shall conform to the requirements as tochemical composition specified in Table 1.4.2 The manufacturer shall furnish an analysis of eachshipment showing the percentage of each element specified.5. Size5.1 The grade is available

7、in sizes as listed in Table 2.NOTE 1The sizes listed in Table 2 are typical as shipped from themanufacturers plant. Ferrovanadium has a friability code number of “1”.It is a tough material, susceptible to little, if any, breakage during shipmentor handling.6. Chemical Analysis6.1 The chemical analys
