I could not find pressure-temperature rating of A-182 Gr. F11 Cl.1 in ASME B16.5-2013ed. May i used pressure-temperature rating of A-182 Gr.F11 Cl.2. Thanks.

It's not a listed material in B16.5, see table 1A. Unless you can bring it under B16.5 para 5.1(d), the short answer is no; you cant use B16.5 tabulated values for F11 Cl.2 instead.
Please note that the current B16.5 edition is 2017.
