ALLOY TOOL STEEL DATASHEET - DIN 200CrMn8
MATERIAL CATEGORY - Cold work alloy tool steel
TYPICAL APPLICATIONS
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.
Cutting tools
Mechanical parts
Air hammer tools
Piercing tools
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 softened condition.
Final heat treatment - heat treatment / QT
