Material Notes:
AK Steel NITRONIC® 19D is a stainless steel with a mixed ferrite and austenite structure. This alloy provides high yield strength (65 ksi minimum {448 MPa}), good drawing and welding characteristics, excellent chloride stress corrosion cracking resistance, and high cyclic oxidation resistance up to 1800°F (982°C). It also exhibits high ductility (super plasticity) at high temperatures (1800°F {982°C}). Compared to similar duplex stainless alloys such as 2205, NITRONIC 19D Stainless Steel is more economical but less corrosion resistant due to lower alloy content (particularly molybdenum). Inclusion in ASTM A 240 has been granted and the alloy is listed in the A 240-97a publication dated March 1998.Information provided by AK Steel
