Specificatioin GB/T 20410 Steels for Turbine Mechanical Parts at high tmperature 45Cr1MoVA Stock Available Round bar, 45Cr1MoVA Flat bar and bolts and nuts
TECHNICAL DATASHEET - GB 45Cr1MoVA
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.
Bars are usually supplied bright in the annealed condition, or bright annealing specially.
Final heat treatment - Quenched and tempered.
Service temperature: 480 ℃ Max.
Stock Available: Round bar diam. 20 ~ 350mm
