Material Notes:
AK Steel 13-4 SR Stainless Steel is a ductile weldable ferritic with 13% Cr and 3.75% Al. The high aluminum content results in a base alloy with high electrical resistivity. It is intended for use where electrical energy needs to be dissipated or heat is generated. Good oxidation resistance to 1800 °F (982 °C) permits applications at elevated temperatures. The alloy’s wet
corrosion resistance is comparable to ferritic alloys Type 409 or Type 430.Information provided by AK Steel.
