17-7PH Stainless Hlau Bar (UNS S17700, AMS 5644)

Peb cov khoom tshwj xeeb 17-7 PH (AMS 5644) muaj lub npe haum ntau dua hauv kev lag luam-'King of Spring Steel'. Nws qhov tshwj xeeb tshaj plaws tsis yog nws 'hardness', tab sis lub peev xwm los hloov pauv ntawm 'zoo heev formability' thiab 'ultra-siab elasticity' los ntawm kev kho cua sov sib txawv 'cov lis dej num,' ua tiav qhov kev xav tau ua ke. Qhov no ua rau koj muaj kev ywj pheej tsim ntau dua li cov ntaub ntawv nrog cov khoom ruaj khov.

Xaiv AMS 5644 stainless hlau tsis yog tsuas yog tau txais ib qho khoom kim heev; nws yog hais txog kev xaiv cov txheej txheem tsim khoom rau cov khoom siv elastic zoo, ua kom zoo los ntawm kev sim nruj hauv kev lag luam aerospace. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov ntawv thov xws li aero- lub cav ntim cov nplhaib, qhov tseeb ntawm cov khoom siv kho mob, satellite kav hlau txais xov xa cov tshuab, thiab siab - zaus teb diaphragms thiab hauv qab. Peb tsis yog tus xa khoom xwb; peb cia siab tias yuav yog koj "cov khoom siv thiab cov txheej txheem kev koom tes" hauv kev txhim kho siab -kev ua tau zoo elastic Cheebtsam.

Raws li kev soj ntsuam cov khoom siv thiab peb cov qauv Tshuag uas twb muaj lawm, peb tuaj yeem sau ua "17-7 PH Heat Treatment Process Guide" rau koj siv. Ib qho qauv me me hauv xeev A tuaj yeem yuav khoom los ntawm koj los yog muab rau koj ua khoom plig; koj tuaj yeem siv nws rau kev xeem txheej txheem. Tsis tas li ntawd, peb yuav muab koj lub rooj sib tham video piav qhia txog cov ntaub ntawv zoo sib xws ntawm cov roj tswj lub caij nplooj ntoos hlav rau qee lub cav qauv (uas tau muab cais tawm), nyob ntawm qhov xwm txheej.

"Lub khawv koob ntawm 17-7 PH (UNS S17700) nyob rau hauv nws peb-kauj ruam kev kho cua sov txheej txheem, uas txawv nws los ntawm lwm yam PH steels (xws li 17-4 PH).

• 'Mos Khoom Qab Zib' Lub Xeev: Txoj Cai A (Kev daws teeb meem kho mob)

Nyob rau theem no, nws yog mos heev, nrog ib tug hardness ntawm tsuas yog ib ncig ntawm HRC 20. Nws tuaj yeem yooj yim undergo complex txias dov, txias kos duab, thiab stamping rau ntau yam duab ntawm springs, diaphragms, thiab bellows. Qhov no yog qhov yuav tsum tau ua ua ntej rau kev tsim cov khoom siv elastic; ntau lub siab - cov ntaub ntawv muaj zog yog qhov nyuaj dhau los ntawm qhov pib thiab tsis tuaj yeem ua rau cov duab nyuaj.

• 'Shaped' Lub Xeev: Cov xwm txheej TH1050" (Nruab nrab Conditioning)

Tom qab A-lub xeev molding, koj yuav tsum tau muab tso rau hauv lub qhov cub 760℃tshav kub kho rau 90 feeb, ces cua- txias nws mus rau hauv qab 15℃. Cov kauj ruam no hu ua 'conditioning'. Nws hloov pauv qee qhov austenite hauv cov khoom siv rau hauv martensite thaum ua kom tiav cov duab thiab muab kev txhawb zog rau thawj zaug, npaj nws rau qhov kawg ntxiv dag zog. Cov kauj ruam no ua kom ntseeg tau tias qhov tseeb molding yuav tsis raug cuam tshuam rau hauv cov khoom kawg.

• 'Lub Caij Nplooj Ntoos Hlav' Lub Xeev: Lub Sij Hawm CH900 (Lub Xeev Ua Ntej Ua Ntej Ua Ntej)

Finally, age it at 480°C for 1 hour. After this step, the yield strength of the material will instantly jump to >1240 MPa, dhau los ua - cov khoom siv caij nplooj ntoos hlav saum toj kawg nkaus nrog cov kev txwv siab heev thiab muaj zog heev rau kev so.

"Cov tuav peb muab nruj me ntsis ua raws li 17-7PH AMS 5644 aerospace cov ntaub ntawv tshwj xeeb, uas yog nruj dua li cov lag luam-qib ASTM A693, kom ntseeg tau tias muaj siab dawb huv thiab ua haujlwm zoo ntawm cov ntaub ntawv."

Cov ntaub ntawv no xav kom peb nkag siab zoo txog AMS 5644 tus qauv tsim khoom. Tsuas yog nrog kev nkag siab tob txog tus qauv tuaj yeem tsim cov ntaub ntawv, thiab peb kuj yuav tsum tau coj peb cov neeg siv khoom yuav ua li cas thiaj li tau txais cov ntaub ntawv tsim nyog.

1. Cov Lus Qhia Txog Kev Muag Khoom:

"Kuv pom zoo kom koj qhia meej meej rau koj cov duab kos: '17-7 PH, UNS S17700, AMS 5644 tus qauv, thawj qhov kev xa khoom yog Tus Txheej Txheem A (lub xeev daws teeb meem)'. Qhov no yuav pab koj ua tiav thaum tau txais.

2. Cov ntsiab lus tseem ceeb rau kev ua thiab kev kho cua sov:

"Yog tias koj yuav cov ntaub ntawv raw thiab ua rau koj tus kheej, ntawm no yog peb lub tswv yim tseem ceeb. Ntau tus neeg tsim khoom tau raug kev poob vim qhov no:

Kev tsim yuav tsum ua kom tiav hauv Cov Cai A! Tsis txhob sov- kho ua ntej tsim, vim qhov no yuav ua rau tawg.

Tom qab 'TH1050' kev kho mob, xyuas kom txias kom qis dua 15℃(zoo dua hauv dej khov); kev hloov dua siab tshiab yuav tsis tiav, thiab lub zog kawg yuav tsis txaus.

Rau 'CH900', qhov kub thiab txias yuav tsum yog qhov tseeb, thiab lub sijhawm txaus. Peb pom zoo kom siv lub cub tawg nrog cua ncig thiab lub ntsuas kub tswj. Peb tuaj yeem muab cov txheej txheem kho cua sov uas tau lees paub. "

3. Muab ob npaug rau Kev Ntsuam Xyuas Zoo:

"Peb muab daim ntawv qhia ua tiav AMS 5644-raws li Cov Khoom Siv Tshaj Tawm (MTR). Txhawm rau kom cov khoom kawg qhov zoo, peb ua cov kev tshuaj xyuas zoo, suav nrog cov tsos, tshuaj muaj pes tsawg leeg, kuaj hardness, thiab dimensional tolerances. Rau koj, ob kauj ruam yog qhov tseem ceeb:

Cov khoom xa tuaj PMI (Spectroscopic) Kev Tshawb Fawb nrawm: Ua kom pom tseeb ntawm kev ntsuas cov ntsiab lus ntawm txhuas (Al). Aluminium tsis txaus yog qhov ua rau lub zog tsis txaus.
