304 0.08 2.00 1.00 18.0 - 20.0 8.0 - 11.0 - - Standard 18/8 austenitic grade. Very good fabrication characteristics with high corrosion resistance.
304 L 0.030 2.00 1.00 18.0 - 20.0 8.0 - 12.0 - - Good resistance to intergranular corrosion for heavy section welding and high temperature applications.
316 0.080 2.00 1.00 16.0 - 18.0 10.0 - 14.0 2.0 - 3.0 - Higher resistance than 304 to general corrosion and pitting.
316 L 0.030 2.00 1.00 16.0 - 18.0 10.0 - 14.0 2.0 - 3.0 - Good resistance to intergranular corrosion for heavy section welding and high temperature applications.
316 Ti 0.080 2.00 1.00 16.0 - 18.0 10.0 - 14.0 2.0 - 3.0 N 0.10 Ti5x(C+N)-0.70 Titanium stabilised 18/8 steel for high temperature applications.
321 0.080 2.00 1.00 17.0 - 19.0 9.0 - 12.0 - Ti5x(C+N)-0.70 Titanium stabilised grade resists intergranular corrosion. For high temperature applications.
Ferritic                
430 0.12 1.00 1.00 16.0 - 18.0 - - - Good combination of corrosion resistance and formability. Non hardenable, used for cold headed fasteners.
430 F 0.12 1.25 1.00 16.0 - 18.0 - - S 0.25min Free machining version of 430.
Martensitic                
410 0.15 1.00 1.00 11.5 - 13.5 - - - Hardenable to achieve best strength and corrosion resistance.
416 0.15 1.25 1.00 12.0 - 14.0 - - S 0.15min Free machining hardenable grade. Corrosion resistance not as good as for 410.
420 0.16 - 0.25 1.00 1.00 12.0 - 14.0 - - - Higher carbon content than 410 gives higher hardness for cutlery, knife blades, dies and surgical instruments.
431 0.20 1.00 1.00 15.0 - 17.0 1.25 - 2.50 - - High strength, excellent toughness and corrosion resistance similar to that of 304. Used for pump shafts, bolts and valve components.
