17-4 PH Round Stainless Hlau Bar (UNS S17400 / AMS 5622)
Hom martensitic nag lossis daus hardening stainless hlau no feem ntau siv nyob rau hauv aircraft cav mounts, tsaws iav Cheebtsam, phais cov cuab yeej, orthopedic cov cuab yeej (tsis yog{0}}implantable), thiab kho hniav xyaum. Nws nta yooj yim "ib qho- nyem hardening," zoo corrosion kuj, thiab lub zog zoo heev - rau - qhov hnyav piv.
Ntawm no, kuv xav qhia ob hom 17-4 PH Round Stainless Steel Bars uas peb nquag muab. Ib qho yog nyob rau hauv A temper, uas yog tsim rau machining vim nws tsis tshua muaj hardness nyob rau hauv cov tshuaj -kho lub xeev thiab zoo heev machinability, zoo li dawb-txiav steel. Qhov no yog ib qho laj thawj tseem ceeb rau nws txoj kev siv dav. Lwm hom yog nyob rau hauv H900 temper, qhov twg machining yog txwv. Thov nco ntsoov tias yog tias koj yuav H900 tempered stainless hlau tuav, muab lawv qhov hardness thiab brittleness, peb tsuas tuaj yeem ua cov haujlwm ua haujlwm tsawg xws li kev sib tsoo thiab EDM. Tej kev ua haujlwm xws li tig, milling, thiab drilling yog nruj me ntsis txwv tsis pub; txwv tsis pub, lub cuab yeej yuav nti, lossis cov khoom yuav tawg.
Specifications thiab Industry Standards
Daim ntawv thov kom meej (RFQ) rau 17-4 PH Round Stainless Steel Bar yog ib nrab ntawm kev sib ntaus sib tua. Peb yuav lees paub cov lus teb kawg rau cov lus nug hauv qab no nrog koj nyob rau theem pib:
1. Koj Cov Khoom Siv Khoom Zoo thiab Qib:
Bar Khoom Standard: ASTM A564 (General Standard) los yog AMS 5643 (Aerospace Standard, Stricter) los yog lwm yam.
Unified Qib: UNS S17400.
Hom Hom: "17-4PH (UNS S17400), Mob H900, Ua raws li tus qauv ASTM A564."
2. Specifications thiab Conditions (Lifeline Clauses):
Koj tuaj yeem pom qhov koj xav tau hauv peb cov khoom muag tsis tu ncua. Peb feem ntau Tshuag tuav los ntawm Ф4mm mus rau Ф600mm. Txawm li cas los xij, tej zaum yuav muaj cov xwm txheej uas cov khoom tsis tshua muaj thiab tsis muaj cov khoom muaj rau kev txiav txim. Piv txwv li, aerospace bars ntawm AMS 5643 / AMS 5622 xav tau kev cai xaj pib los ntawm theem metallurgical. 2. Koj yuav tsum tau tham txog txoj kab uas hla, ntev, thiab kam rau ua nrog peb (H11 yog ib qho kev siv siab ua siab ntev).
Tus me nyuam qhov xwm txheej: Yuav tsum tau teev nyob rau hauv cov ntawv loj, piv txwv li: Cov xwm txheej A (Kev daws teeb meem) lossis Cov Txheej Txheem H900 (hnub nyoog).
3. Cov Lus Qhia Tshwj Xeeb (Ntxiv raws li xav tau):
Tsis yog-Kev kuaj kev puas tsuaj: Rau qhov tseem ceeb rotating Cheebtsam (xws li twj tso kua mis), 100% ultrasonic kuaj (UT) yuav tsum tau.
Mechanical Property Guarantee: Qhov ntsuas qhov muaj zog ntawm qhov muaj zog hauv H900 tus neeg mob tuaj yeem teev nyob rau hauv daim ntawv pov thawj zoo.

Peb muab peb qhov kev xa khoom siv ntau tshaj plaws: Qhov A (bar stock condition rau tom qab machining; softer, machinable), H900 (feem ntau siv siab - lub zog muaj zog; ua ntej- tshav kub- kho cov tuav tiav, lossis cov xwm txheej A tuav thiab machined thiab hnub nyoog ntawm koj tus kheej), thiab 50 lub zog zoo dua corrosion, sib npaug H1. Cov no muaj rau koj xaiv.
Cov ntsiab lus tseem ceeb rau kev yuav khoom:Koj yuav tsum qhia meej meej qhov kev xa khoom ntawm cov khoom yuav khoom. Puas yog "Ib yam mob" uas koj yuav ua thiab ua kom sov- kho koj tus kheej, lossis koj puas xav kom tus neeg muag khoom muab cov khoom tiav hauv "H900 condition"? Tus nqi, kev siv, thiab kev ua haujlwm ntawm ob qhov sib txawv heev.
Kev soj ntsuam zoo
- Cov ntaub ntawv tshuaj xyuas:
Peb yuav muab Daim Ntawv Qhia Txog Cov Khoom Siv (MTR): Qhov no yuav tsum suav nrog cov tshuaj muaj pes tsawg leeg thiab ntsuas cov khoom siv kho tshuab rau lub siab sib xws.
- Kev tshuaj xyuas lub cev: Peb qhov kev tshuaj xyuas feem ntau muaj cov kauj ruam hauv qab no:
1. Dimensions thiab Appearance: Tshawb xyuas lub cheeb ntawm 17-4 PH Stainless Steel Bar thiab xyuas cov kab nrib pleb thiab folds ntawm qhov chaw.
2. Chemical Composition Verification (PMI): Qhov no yog qhov tseem ceeb tshaj plaws thiab muaj txiaj ntsig zoo ntawm - txoj kev kuaj qhov chaw. Siv lub spectrometer portable los tsom xyuas cov ntsiab lus ntawm chromium (Cr), tooj liab (Cu), thiab niobium (Nb).
Cr: Xyuas kom nws siab dua 16% los lav nws yog stainless hlau.
Cu: Qhov tseem ceeb! Yuav tsum muaj ntau dua lossis sib npaug li 3.2%. Cov ntsiab lus tooj liab tsis txaus yog ib qho ua rau tsis muaj zog. Ntau yam pheej yig "lwm txoj kev" txo cov ntsiab lus tooj liab.
Nb: Kev nyeem ntawv yuav tsum tau muab; Qhov no yog cov yam ntxwv ntawm 17-4 PH.
3. Kev Ntsuam Xyuas Hardness (Fastest thiab Zoo Tshaj Plaws):
Yog kev yuav khoom hauv npau taws A: Ntsuas HRB lossis HRC; Nws yuav tsum tsawg dua los yog sib npaug rau HRC 32. Cov hardness ntau dhau qhia tias tsis txaus annealing, ua rau kev ua haujlwm nyuaj.
Yog yuav H900 temper: Ntsuas HRC; nws yuav tsum nyob rau hauv qhov ntau ntawm 40-48. Qhov no yog cov pov thawj ncaj qha ntawm kev lees txais lub zog.
Yog tias xav tau daim ntawv pov thawj kev xeem, nws yuav tsum tau tham ua ntej. Thib peb-kev kuaj xyuas cov khoom yuav raug npaj. Peb yuav xa cov qauv mus kuaj, thiab daim ntawv tshaj tawm feem ntau yuav xa tuaj rau koj nrog rau cov khoom.
Tiv tauj peb kom paub ntau ntxiv.
