MATERIAL DATA SHEET - W-Nr 1.2002
MATERIAL CATEGORY - Cold work alloy tool steel
Air hammer tools
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 softened condition.
Final heat treatment - heat treatment / QT
MATERIAL SPECIFICATIONS - EN ISO 4957: 2000 , DIN 17350
Round bar / flat bar / plate / tube / forge piece
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft
