MATERIAL TECHNICAL DATA SHEET - W-Nr 1.6956
MATERIAL CATEGORY - hardened and tempered steel 
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 - Q + T.
