DIN EN 10083-2 hardened and tempered steel 1.5864 Round bar, flat bar, plate 1.5864 stock available, Melting, ESR & VAR technique, Heat treated, cold drawn rod
MATERIAL DATA SHEET - 1.5864
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.
Final heat treatment - quenched and tempered.
