ALLOY TOOL STEEL - DIN 85CrMo7
MATERIAL CATEGORY - Alloy steel
Alloy tool steel is widely used to produce the cutting tool, cold/heat distortion mould and measuring implements,
and further to manufacture the piston, valve, valve seat of fuel pump of diesel engine.
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
EN ISO 4957: 2000 , DIN 17350 (1980)
Black bar / Flat bar / Square bar
Bright - peeled + polishing, centerless grinding
Forged - ring /tube /pipe casing /discs /shaft
