Smelting method of C-276 hastelloy

The invention provides a smelting method of C-276 hastelloy. The smelting method comprises the following technical steps of step 1, rolling for the first time; step 2, annealing for the first time; step 3, rolling for the second time; step 4, annealing for the second time; step 5, rolling for the third time; step 6, annealing for the third time. Through the cold rolling process, the organization structure of a material can be fully crushed, the material annealing process is debugged through continuous heat treatment, it can be ensured that the performance of the material meets the requirement, and after the first rolling process, the second rolling process and the third rolling process, the surface of a casting blank is cleaned through a stainless steel brush. Then the casting blank is immersed in a mixed acid solution to be subjected to acid pickling, so that an oxide layer on the surface of the casting is cleaned, and the toughness and strength of the C-276 hastelloy are further improved. 本发明提供了一种C-276哈氏合金的
