Material & Applications
Why Stainless Steel F304/F316: F304 provides general corrosion resistance for chemical and process service. F316 adds molybdenum for pitting and chloride resistance. The “L” grades (F304L/F316L) have lower carbon (≤0.03%) to prevent sensitization during welding, but have lower temperature limits and pressure ratings.
Typical applications: Chemical plants, pharmaceutical manufacturing, food & beverage, pulp & paper, marine, and any small-bore application requiring corrosion resistance. F316 for chloride environments. F304L/F316L for welded construction where sensitization is a concern.
