NB/T 20007.27-2013Stainless steel for pressurized water reactor nuclear power plants - Part 27: Cast elbows and inclined nozzles made from austenitic-ferritic stainless steel for reactor coolant piping (English PDF)

NB/T 20007.27-2013 is the English-translated version of 压水堆核电厂用不锈钢 第27部分：反应堆冷却剂管道用奥氏体-铁素体不锈钢铸造弯头和斜接管嘴.

NB/T 20007.27-2013 is Part 27 of the Chinese energy industry series on stainless steel for pressurized water reactor nuclear power plants, written for cast elbows and inclined nozzles of austenitic-ferritic stainless steel in reactor coolant piping.

Taking the two shapes together as castings, it covers their manufacture, their chemical composition, their properties and the examination of their structure. The components are those forming part of the coolant piping run inside the plant.

The standard is classified J15 in China and 77.140.80 internationally, which groups it with steel castings for pressure service. Composition is checked through the GB/T 223 series of chemical analysis methods for iron and steel. Issued on 8 June 2013, it has applied since 1 October 2013.
