Title: Electric heating fe-cr-al alloy
Inventor: NOZUMI GOROU
IPC: C22C38/28
Filed: 1985-03-20
Abstract: PURPOSE:To considerably prolong the life of the titled alloy at high temp. by lowering the C+N content in the composition of the alloy. CONSTITUTION:This electric heating alloy consists of, by weight, 17-21% Cr, 2-4% Al, <=1.5% Si, <=1.0% Mn, <=0.5% Ti, <=0.030% C+N and the balance Fe of further contains <=0.5% rare earth element. As the C content in an electric heating alloy at high temp. is increased, the penetration of O2 in the air into the alloy is increased, so the inside of the alloy is liable to cause abnormal oxidation. As the N content is increased, N bonds to Al which contributes largely to the oxidation resistance, forming AlN, so the effect of Al is reduced. When the C+N content is lowered, it is assumed that a synergistic effect by which abnormal oxidation and deterioration in the oxidation resistance are inhibited is produced to prolong the life. The life of the electric heating element having <=0.030% C+N content at 1,300 deg.C is improved about 2.5 times the life of a conventional alloy.
