Carburized structural steel 1.8504 peeled round bar, flat bar, plate, cold drawn rod, ESR, hot forged, rolled, heat treated, cold finished
Official Test Certificate: issued by TUV - SGS - BV
TECHNICAL DATA SHEET - 1.8504
MATERIAL CATEGORY - Carburized structural 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.
Final heat treatment - quenched and tempered.
