New knowledge from development of high alloy steels and alloys for WWER-440 and WWER-1000 light water reactors
Description
The solution is described of technology problems concerning steels 08Kh18N10T and 10Kh11N10T3R and alloy KhN35VT for WWER type reactors. For steel 08Kh18N10T deoxidation, aluminium was suggested to be replaced by calcium alloys, which improves the Ti carbonitride inclusion number by one degree. The occurrence of macrostructure defects in rods from steel 10Kh11N20T3R was limited by electroslag remelting of ingots and by a forming process modification. In order that the specified parameters of alloy KhN35VT should be attained, it is necessary: 1. to complete the technological process by remelting in a vacuum arc furnace; 2. to exclude forming operations with a low degree of deformation in which a circumferential coarse grain strip appears; 3. to reduce the dissolution annealing temperature to 960 degC.
