ODIL has a complete famliy of all of our stainless steal grades. Our Stainless Steel Comparator offers a brief description of all of our stainless steel grades.

Ferritic, or nonhardenable stainless steels, are classified in the 400 series, usually with 10% to 20% chromium content, and are normally specified due to superior corrosion resistance and resistance to scaling at elevated temperatures.

Martensitic , or hardenable stainless steels, are classified in the 400 series, usually with 11.5% chromium up to 18% chromium, with higher levels of carbon than ferritics, and are capable of being heat treated to a wide range of hardness and strength levels.

Austenitic, or nonmagnetic stainless steels, are classified in the 200 and 300 series, with 16% to 30% chromium and 2% to 20% nickel for enhanced surface quality, formability and increased corrosion and wear resistance, and are nonhardenable by heat treating.

Precipitation Hardening stainless steels, or hardenable chromium-nickel alloys, are classified as martensitic or semi-austenitic. They develop their high strength and hardness through a variety of heat treatments. They are used in aircraft parts and commonly viewed as bar alloys, but are also available in flat roll products with a very high strength-to-weight ratio.

Duplex alloy stainless steels contain a mixture of austenite and ferrite in their structure, and exhibit characteristics of both phases with higher strength and ductility. Nitrogen is added to the second generation duplex alloys and provides strength and improved weld ability.
