DATA SHEET - ALLOY TOOL STEEL DIN X45NiCrMo4 / W-Nr 1.2767
MATERIAL CATEGORY:  Cold work alloy tool steel 
Cold work die includes cold punching mould, wire-drawing die, drawing die, coining die, thread rolling die, cold heading die, cold extrusion die, Based on the working condition, cold work die should have the high hardness, strength, abrasion resistance, toughness, hardenability, quenching degree, and other processing property. This kind of alloy tool steel belongs to  high carbon alloy steel (carbon mass fraction is over 0.80%), Chromium is key element of alloy with mass fraction below 5% generally. 
MATERIAL SPECIFICATIONS  
 EN ISO 4957: 2000 , DIN 17350 (1980)
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 = SA condition.
Final heat treatment - heat treatment /  spheroidizing annealing
AVAILABLE SHAPES  
Black bar /Flat bar /Square bar 
Bright - peeled + polishing /centerless grinding / peeled + slidabrading
Forged - ring /tube /pipe casing /discs /shaft

HEAT TREATTMENT PRACTICE 
The preheating of measuring and cutting tool steel is spheroidizing annealing, final heat treatment is quenching + low temperature tempering and hardness after heat treatment can reach 60~65HRC. When heat treat tool steel grades consideration should be given to hardening temperature, including ratio of heating, cooling and soaking times which will differ due to factors such as the shape and size of each chemical component. Other considerations during heat treatment include the type of furnace, quenching medium and work piece transfer facilities.
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
