316 & 316L Stainless Steel

Properties of 316 & 316L Stainless Steel

316 stainless steel is a molybdenum-bearing austenitic material that exhibits various beneficial qualities, including:

  • Strength
  • Creep resistance
  • Rugged toughness
  • Excellent mechanical properties
  • Corrosion resistance (especially in low temperature applications) 

Additionally, the molybdenum content within 316 stainless steel provides for an increased resistance to pitting and crevice corrosion within marine environments, and when exposed to high-chloride chemicals and acids. 316L stainless steel is a low-carbon variation, with a maximum carbon content of 0.03%. This minimizes harmful carbide precipitation caused by welding, allowing for 316L's use in as-welded condition (with no post-weld annealing) in corrosive applications.

316 Stainless Steel Hardness 

Annealed 316 stainless steel has a Brinell scale hardness of 149, and Rockwell hardness of B80. 316 stainless steel materials cannot be hardened via heat treatment.

Heat Treating 316 Stainless Steel

316 stainless steel can be annealed by heating the material to 1900-2100°F (1038-1149°C) for 60 minutes per inch of thickness and cooling/quenching rapidly. A final annealing temperature of 1950°F will imbue the greatest corrosion resistance. Neither 316 nor 316L stainless steel can be hardened via heat treating.

316 Stainless Steel Machinability 

Like all austenitic grades, 316 and 316L stainless steel work harden rapidly; because of this, heavy positive feeds should be considered. To prevent glazing, rigidly supported tools with the heaviest possible cut should be used. The machining 316/316L stainless steel creates a rough, stringy swarf.
