As a result, Type 304L stainless steel is a sort after material for use in severely corrosive conditions. Weld annealing is only necessary in applications where stress loads are excessive.
Benefits of using 304L Stainless Steel
Low carbon content eliminates carbon precipitation in the welding process
Can be used in severe corrosive environments
Weld annealing only required in high stress applications
Very similar to Type 304
304 & 304L plate and pipes have similar properties and in certain cases are stocked with Dual Certification, where it is concluded that each item has properties and a composition which comply with both steel types. Grade 304H cannot be included in this equation due to the steel's higher carbon content which is intended for use in elevated temperature applications.
