Introduction
Grade 301 is a cheaper alternative to the traditional high-nickel austenitic stainless steels such as grade 304. Grade 301L stainless steel is a low carbon steel which is ideal for improved ductility and when heavy sections are to be welded. Unlike welds in grade 301, grade 301L does not need to be annealed for maximum corrosion resistance.
