Specificatioin GB/T 20410 Steels for Turbine Mechanical Parts 2Cr12NiMo1W1V Stock Available Round bar, Flat bar 2Cr12NiMo1W1V bolts and nuts
MATERIAL DATASHEET - GB 2Cr12NiMo1W1V
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: 565 ℃ Max.
Stock Available: Round bar diam. 20 ~ 280mm
