The study found that To determine the microstructure The size of the grain size is no different test pieces in 2101 and 2205, even longer. The percentage of chromium deficiency increases with temperature and time increased test piece 316L percent chromium deficiency caused little. The chromium deficiency that affects the mechanical properties of hardness is no difference in grade 316 L, but the hardness grade in 2101 and 2205 to increase the hardness slightly lower.
