| Abstract: | pieces of stainless steel heavy forgings used for the reactor core and the argon decay vessel in China Experimental Fast Breeder Project have been developed, the largest one of which is 1370/1190×2110mm. The nonmetallic inclusions( nitride inclusive) are in the grade of 0.5-1.0. Austenitic grain size is grained to grade 5. σ 0.2 >160Mpa at 550℃. The defects ≥2mm were not found during ultrasonic test. All the products are qualified during the acceptance and delivered as well. |
