Aisi 430

Abstract An electrochemical potentiokinetic reactivation (EPR) test has been developed for quantifying the degree of sensitization of ferritic stainless steels (SSs). This test is applicable to AISI 430, 430 Ti, 430 Nb, 434, 444, and 446. The test is conducted at 30 C in a deaerated 3 to 5 N H2SO4 solution. A test specimen is first passivated at + 400 mVSCE for 2 to 10 min, depending on the grade of SS, and then subjected to a reactivation step where the potential is decreased at a rate of 100 to 250 mV/min toward the open circuit potential (OCP) to determine whether a reactivation peak occurs. Results of the EPR test agree well with those of the Cu-CuSO4-50% H2SO4 immersion test.

Magnetic Applications

Abstract MAGIVAL MG2 is a free machining ferritic stainless steel grade with the same high machinability and corrosion resistance as type 430F, but offering a higher magnetic permeability and lower coercive force than MG1 (Alloy Digest SS-1159, October 2013). Magival is a group of easily workable ferritic stainless steels developed for magnetic applications where high permeability and low coercive force are required. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on corrosion resistance as well as forming, heat treating, and joining.
