ALLOY STEEL DATA SHEET - Grade 1.7735
MATERIAL CATEGORY - hardened and tempered steel 
PRODUCT DESCRIPTION
The alloy is usually produced by BEF / 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 - heat treatment / QT
