Nta
Ntshiab Strengthening Mechanism
Cr (4.8–5.5%), Mo (1.2–1.5%), thiab V (0.8–1.2%) nyob rau hauv cov ntaub ntawv uas dispersed alloy carbides, uas inhibit dislocation txav thiab ncua softening thaum tempering.
Resistant rau Thermal Fatigue
Cov ntsiab lus nruab nrab carbon (0.35–0.42%) ua ke nrog silicon (0.8–1.2%) txhim kho tempering stability, slowing tawg pib thiab nthuav tawm thaum rov ua cua sov thiab txias.
Controllable Hardness Range Tom qab kho cua sov
Lub hardness tom qab quenching thiab tempering yog tswj nyob rau hauv qhov ntau ntawm 48-52 HRC, sib xws rau lub zog tensile Ntau dua los yog sib npaug rau 1300 MPa. Kev kho cov txheej txheem tuaj yeem ua raws li qhov kev ntxhov siab ntawm cov pwm.
Ntau yam ntawm Section Adaptability
Round tuav los ntawm 20-500 mm thiab daim hlau mus txog 400 mm tuab yog muaj. Ua ke nrog zoo hardenability, qhov sib txawv ntawm hardness faib ntawm sab hauv thiab nto ntawm loj -section workpieces yuav tswj tau.
Daim ntawv thov
Kev lag luam tuag Casting:Siv nyob rau hauv cov kab noj hniav thiab cores ntawm tuag-casting pwm rau txhuas thiab zinc alloys, bearing cov yaig ntawm molten hlau thiab cyclic thermal loads.
Kev lag luam forging:Siv rau hauv kub forging tuag thiab siab-cov kabmob qhov chaw, muab lub zog tsim nyog thiab ua haujlwm rau thermal tawg thaum lub sijhawm siab -kub yas deformation.
Kev lag luam Extrusion:Siv nyob rau hauv cov hlau extrusion tuag, tswj qhov tuag geometry nyob rau hauv tas li kub kub thiab siab kev nyuaj siab.
Pwm Manufacturing Industry:Siv nyob rau hauv cov pwm yas los yog cov yam ntxwv ntawm cov khoom uas yuav tsum tau tshav kub load kuj, bearing cov teebmeem ntawm localized kub nce thaum lub sij hawm tsim txheej txheem.
