TECHNICAL DATA SHEET - Grade 75Cr1
MATERIAL CATEGORY - Cold work alloy tool steel for Saw blade processing
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
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, discs, shaft
Round bar / Wire rod (Diameter): 5.5mm to 600mm
Square bar / Flat bar: 3mm to 600mm
Plate / Sheet steel / Steel strip: 2mm to 600mm
