Welding and machining have conflicting material requirements, with the Sulphur, Selenium or Lead additions that make steels easy to machine creating major headaches when welding. E316L will give you the corrosion resistance you're looking for, but will be difficult to machine because it work hardens so readily. If you can, stress relieve after welding (or in between machining attempts) to return the steel to its fully austenitic condition.</div>
<div dir="ltr">As an alternative to weld deposition, you could look at plating processes to clad the exposed steel. Electroless Nickel?</div>
