Abstract

The invention discloses an SA105 material flange for a fast neutron reactor nuclear power station. The carbon steel flange comprises the following chemical components: 0.15-0.28wt% of carbon, 0.12-0.30wt% of silicon, 0.75-1.35wt% of manganese, less than or equal to 0.015wt% of phosphorus, less than or equal to 0.003wt% of sulfur, less than or equal to 0.15wt% of copper, 0.20-0.40wt% of nickel, less than or equal to 0.12wt% of molybdenum, 0.05-0.08wt% of vanadium and the balance iron, wherein the total content of copper, nickel, chromium, molybdenum and vanadium does not exceed 1.00%, and the total content of chromium and molybdenum elements does not exceed 0.32%. The invention also discloses a manufacturing method of the SA105 material flange for the fast neutron reactor nuclear power station. The manufacturing method comprises the following steps of smelting raw materials; forging; carrying out heat treatment; testing the performance; machining; carrying out nondestructive testing; and obtaining a finished product. By adopting the method, the chemical components are precisely controlled, so that the content of the chemical components powerfully meets the performance requirement. The nuclear power carbon steel flange and a forge piece have relatively high requirements on mechanical property uniformity. The uniformity of the chemical components is controlled, component segregation is avoided, and the material performance stability is improved.

Description

technical field [0001] The invention relates to the technical field of carbon steel forging, in particular to a flange made of SA105 used in a fast neutron reactor nuclear power plant and a manufacturing method thereof. Background technique [0002] In the construction and development of nuclear power plants, the second-generation nuclear power plants and the third-generation nuclear power plants have been experienced. The nuclear power plants under construction are basically the third-generation pressurized water reactor nuclear power plants, and their safety performance is significantly higher than that of the second-generation and second-generation + nuclear power plants. At present, most of the nuclear power plant flanges and forgings undertaken by our company are pressurized water reactor models. We have many years of production experience and the manufacturing process is mature and stable. Generally, pressurized water reactors use 3% to 4% enriched uranium 235 as raw m...
