I suppose there are 2 types of Nickel Alloys, Solid solution strengthened and Precipitation Hardened alloys.

Inconel 601 falls under Solid solution strengthened and supplied in  Solution Annealed Heat Treated condition.

ASTM A 380 is pickling and passivation standard for stainless steel.

it is better to contact the Manufacturer regarding Pickling and passivation to remove corrosion deposits.

Thanks & Regards

Dear Harenath,

       Due to improper storage, the thermowell of Inconel 601 got corroded. For these items can we do pickling and passivation?

What is the conditions of material.
Is it heat treated normalised or something else.
