Heat treatment services for CNC machining
What is heat treatment of metal?
Metal heat treatment is a process method that places metal workpieces in a certain medium for heating, heat preservation and cooling, and controls their performance by changing the surface or internal organizational structure of metal materials.
Why do parts need heat treatment?
Which parts are suitable for heat treatment?
►Core function: high load, high wear environment
Transmission and power components
Gear/gear shaft : surface carburizing and quenching (HV 800-1200) to improve the wear resistance of the tooth surface, tempering treatment (such as 45 steel) to ensure the toughness of the heart.
Crankshaft/camshaft : induction hardening of journal surface (HRC 55-60), with low temperature tempering to reduce brittleness .
Bearing inner and outer rings : integral quenching + tempering (GCr15 steel), or nitriding treatment (such as aviation bearings) to improve the fatigue strength.
Wear and sealing parts
Brake disc/piston ring : laser surface quenching to form a hardened layer, reduce friction loss .
Mold cavity/punch : vacuum quenching (H13 steel) to avoid oxidation deformation, surface nitriding to extend the service life
►Precision structural parts: dimensional stability and lightweight requirements
Aerospace components
Landing gear/turbine blades : titanium alloy solution aging strengthening (TC4) to improve specific strength and creep resistance.
Aluminum alloy frame : T6 aging treatment (such as 7075 alloy), dimensional stability up to ±0.01mm.
Electronic and optical devices
5G base station shell : aluminum alloy anodizing + aging treatment, taking into account heat dissipation and corrosion resistance.
Precision guide rail : stress relief annealing to eliminate processing deformation, to ensure nanometer precision
►Special working condition parts: corrosion resistance and extreme environment adaptation
Chemical and Medical equipment
Stainless steel surgical instruments : vacuum solution treatment (316L) to ensure biocompatibility and sterile surface.
Pump valve seal : chromized treatment (such as 17-4PH steel), acid and alkali corrosion resistance life increased by 5 times 38.
Energy and Heavy Industry equipment
Wind power gearbox planetary frame : differential temperature quenching (34CrNiMo6 steel), withstand 10MW torque impact 16.
Nuclear bolt : boration treatment to enhance the anti-radiation performance, service life of more than 40 years
