Tuang: ①. Ngurangi wates ndhuwur kanthi karbon 0,011%, saéngga 0,04% Mangan Tambahan. Kanggo ZG 200 ~ 400 mangan nganti 1.00%, sing isih ana papat kelas Mangan Tinggi nganti 1.20%.
②. Jumlah total unsur ora bakal ngluwihi 1,00%. Yen panuku ora mbutuhake, unsur residu bisa uga ora dianalisis.
③. Nalika tungku asam digunakake kanggo ngasilake pemotong, isi s lan p bakal disepakati karo loro pihak.
