DIN EN 10083-2 hardened and tempered steel 35NiCr18 Round bar, Flat bar, Plate 1.5846 forgings, ESR, hot forging, Hot rolling, Heat treatment
TECHNICAL DATA SHEET - DIN 35NiCr18
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 - heat treatment / QT
