Stainless Steel Specifications by Grade
304 - Chromium-Nickel austenitic alloy used in a wide range of applications.304L - Chromium-Nickel austenitic alloy used in a wide range of applications.
316L - Molybdenum bearing austenitic stainless steels which are more resistant to general corrosion and pitting/crevice corrosion.
317L - Molybdenum bearing austenitic stainless steels with increased resistance to chemical attack compared to standard chromium-nickel austenitic stainless steels.
317LMN - 317L + increased levels of moly and nitrogen for enhancing resistance to pitting and crevice corrosion.
304H - Modification of 304 in which the carbon content is controlled to a range of 0.04 – 0.10 to provide improved high temperature strength.
321/321H - A stabilized stainless steel which has excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F.
347/347H - Stabilized stainless steel which offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium precipitation range from 800 to 1500°F.
309/309S - Austenitic stainless steel used in applications where elevated temperatures are present.
310S - Austenitic stainless steel used in applications where elevated temperatures are present.
410 - Hardenable, straight-chromium stainless steel which combines superior wear resistance with excellent corrosion resistance.
2304 - A high chromium-low nickel-moly free duplex stainless steel exhibiting improved strength and stress corrosion resistance properties compared to 304/316 austenitic stainless steels.
2205 - A high chromium-nickel-moly duplex stainless steel providing high strength and superior resistance to general, local, and stress corrosion compared to 316L or 317L.
2507 - A chromium-nickel-moly super duplex stainless steel with exceptional strength and corrosion resistance in the chemical process, petrochemical, and seawater environments.
17-4PH - Martensitic stainless steel that is capable of precipitation hardening. This stainless steel has very high strength and hardness.
