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
Round bar / flat bar / hollow bar / forgings / tube
Bright - peeled + polishing /centerless grinding / peeled + slidabrading
Forged - ring /tube /pipe casing /discs /shaft
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.
PRODUCT PROFILE & DIMENSIONS
Round bar / Wire rod (Diameter): 5.5mm to 500mm
Square bar / Flat bar: 3mm to 600mm
Plate / Sheet steel / Steel strip: 0.1mm to 300mm
Width: 8mm to 1200mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
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
