Final answer:
E308-16 is the correct stainless steel electrode, used for welding 304 stainless steel with 18% chromium and 8% nickel, indicating its flux composition and current type.
Step-by-step explanation:
The stainless steel electrode in the options provided is E308-16. This designation refers to an electrode that is commonly used for welding 304 stainless steel, which contains 18% chromium and 8% nickel. The –308” refers to the type of stainless steel alloy, and the –16” indicates the electrode’s flux composition and current type which in this case means it has a lime-titania coating and is used with DC reverse polarity or AC current.
