Abstract
Shapes having a high corrosion resistance at elevated temperature consist of by weight:- <TABS:0899970/II/1> or <TABS:0899970/II/2> The shapes are made by pressing and sintering according to known powder metallurgical methods. Examples are described in which pressures of 100 and 200 kg/sq. mm and 2 and 4 metric tons/sq. cm and temperatures of 1800-2000 DEG C. are used.
