Specification GB/T 20410 Steels 1Cr11MoNiW1VNbN Turbine Mechanical Parts, Stock Available Round bar 1Cr11MoNiW1VNbN Flat bar, Bolts, Nuts
MATERIAL DATASHEET - GB 1Cr11MoNiW1VNbN
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: 600 ℃ Max.
