ALLOY STEEL DATA SHEET - Grade 1.7735
MECHANICAL PROPERTIES - HOT WORKING, HEAT TREATMENT AND HARDNESS
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
