MATERIAL STANDARDS DATASHEET - W-Nr 1.2210
MATERIAL CATEGORY - Cold work alloy tool steel
MATERIAL SPECIFICATIONS - EN ISO 4957: 2000, DIN 17350 (1980)
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
Black bar /Flat bar /Square bar
Bright - peeled + polishing /centerless grinding / peeled + slidabrading
Forged - ring /tube /pipe casing /discs /shaft
