GH4169 (Inconel 718) Txias -Tube Txheej Txheem Qhia
GH4169 (Inconel 718) Txias -Tube Txheej Txheem Qhia
The production of GH4169 (Inconel 718) cold-drawn tubing involves multiple cold drawing passes, intermediate annealing (950-1050℃), and high-strength precipitation hardening (aging treatment) to achieve high strength (>1000 MPa) thiab nruj tolerances. Vim nws ua hauj lwm - hardening zog, nquag annealing yuav tsum tau rov qab ductility, thiab meej lubrication yog tsim nyog.
Puas yog Inconel 718 nyuaj rau tshuab?
Cov npib tsib xee no -raws li superalloy yog ib yam khoom siv nyob rau hauv kev lag luam aerospace, muaj lub zog zoo heev thiab kub ua hauj lwm -tab sis cov khoom no ua rau nws nyuaj heev rau tshuab. Inconel 718 yog nquag ua hauj lwm ceev ceev, ua kom kub siab heev ntawm lub cuab yeej -workpiece interface, yog li ua kom ceev cov cuab yeej hnav.

Peb GH4169 txias-txoj raj txheej txheem ntws
Theem 1: Nqus Induction Melting + Vacuum Arc Remelting (VAR) Dual Nqus Melting
Qhov zoo ntawm peb precision tubing originates los ntawm lub cub tawg. Peb ntiav ob lub Nqus Induction Melting (VIM) thiab Nqus Arc Remelting (VAR) cov txheej txheem los xyuas kom meej ib qho ultra-tu microstructure. Qhov no tshem tawm cov uas tsis yog -hlau suav nrog, uas yog cov ntsiab lus pib rau kev qaug zog tawg.
Theem 2: Precision Multi-Drawing thiab Stress Relief
Peb siv qhov tshwj xeeb ntab mandrel thiab txwv tus ntoo khaub lig-sectional thinning (15-22% ib kos). Cov txheej txheem tswj hwm no tswj cov txheej txheem tawv tawv ntawm cov nickel-chromium matrix, tiv thaiv "txiv kab ntxwv tev" cov nyhuv thiab ua kom lub ntsej muag du.
Theem 3: Nqus Bright Annealing (BA)
Txhawm rau daws qhov teeb meem "internal scale", txhua lub raj muaj qhov ci ntsa iab hauv cov ntshiab hydrogen los yog lub tshuab nqus tsev siab. Qhov no ua kom muaj daim iav-zoo li sab hauv txoj kab uas hla (ID), tseem ceeb heev rau kev thauj khoom siab - cov kua dej ntshiab huv hauv aerospace roj kab.
