MATERIAL DATASHEET - W-Nr 1.2369
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 /IFF 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 (peeling or centreless grinding) in the softened condition.
Final heat treatment - heat treatment / QT
