Or there is any other better option to join these two parts?

$\begingroup$ the part will rotate at around 1000 rpm, so there might be chances to lose. $\endgroup$– Rushikesh HandoreCommented Jan 12, 2023 at 11:22

solder generally will not work on stainless steel (it can't stick because of the oxide that forms on the surface of the steel). You can weld it instead, using welding wire or rod specifically compounded to work with stainless. If the join between the two parts is threaded, you can lock them together using a type of glue called thread locker which is effective yet allows the parts to be torqued apart at some later time if necessary.
