MATERIAL DATASHEET - GB 18Cr1Mo1VTiB

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.
Stock Available: Round bar diam. 20 ~ 300mm
