Stainless steel sealed chamber cover copper forging successful
China this product is double the maximum tonnage of ingots of about 17 tons, the heaviest forgings rough about 11 tons, forging such a large size in the country's nuclear forging the first time. In order to ensure the success of forging, China double from second half of 2009 began to study the thermal processing of steel materials and process performance, by contrast, and high temperature performance of thermoplastic and other series of tests to develop a rational process, strict control of the heating rate, heating temperature , holding time, ensure the temperature uniformity of ingot and forging temperature of each fire times. After 8 days before and after forging, three copper ingot 4 precipitation hardening martensitic stainless steel forgings forging success, marking the Chinese nuclear power with a special stainless steel double production capacity and on forging a new level.
The first two sets of domestic nuclear power sealed chamber and seal chamber cover forging factory in forging hydraulic press forging a successful workshop. Batch of forgings is the largest domestic production of copper precipitation hardening martensitic stainless steel forgings, forged its success, marking these products can replace imports to achieve localization.
