Specificatioin GB/T 20410 Steels 2Cr11Mo1VNbN Turbine Mechanical Parts at high tmperature Stock Available Round bar, Flat bar 2Cr11Mo1VNbN bolts, nuts
MATERIAL DATASHEET - GB 2Cr11Mo1VNbN
MATERIAL CATEGORY - Steels for Turbine bolts and nuts at high tmperature
PRODUCT DESCRIPTION
The alloy is usually produced by EAF + VD + LF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the annealed condition, or bright annealing specially.
Final heat treatment - Quenched and tempered.
Working Temperature: 570 ℃ Max.
