15-5 PHNyog martensitic nag lossis daus- hardening stainless hlau ua nyob ib ncig ntawm ib qho teeb meem tshwj xeeb: 17-4PH poob toughness los ntawm cov thickness ntawm cov seem hnyav. Yog tias koj tab tom yuav 15-5PH yeeb nkab lossis phaj, daim duab kos yuav luag paub meej tias nws yog vim qhov pom kev nyuaj siab ntau txoj kev, lossis vim Saudi Aramco lossis ADNOC cov ntaub ntawv tshwj xeeb tau txiav txim siab tawm qib uas tsis tuaj yeem tuav nws cov khoom hla hla ntu ntu tuab.
Nplooj ntawv no suav nrog qib twg tiag tiag, qhov kev qhia tshwj xeeb siv rau daim ntawv twg, qhov kev laus li cas koj xaiv hloov pauv lub zog thiab kev pheej hmoo tawg, thiab qhov twg qhov zoo dua 17-4PH nres tiag tiag.
15-5PH yog dab tsi, thiab yog vim li cas nws tshwm sim txhua
15-5PH tau sau npe ua UNS S15500, xaiv hom XM-12 hauv ASTM A564, thiab paub hauv Tebchaws Europe li 1.4545 (X5CrNiCuNb15-5). Qhov sib xyaw ua ke hloov pauv piv rau 17-4PH yog me me thiab txhob txwm tshaj tawm: chromium poob rau 14.0-15.5%, npib tsib xee nce mus rau 3.5-5.5%, nrog tooj liab 2.50-4.50% thiab niobium + tantalum 0.15-0.45% ua lub zog.
Carbon nyob ntawm 0.07% siab tshaj plaws. Qhov ceev yog hais txog 7.78 g / cm³ thiab qib yog sib nqus nyob rau hauv txhua yam mob. Cov chromium thiab npib tsib xee yog tag nrho zaj dab neeg - hloov qhov sib npaug mus rau npib tsib xee suppresses khaws cia delta ferrite, ua 15-5PH ib delta-ferrite-tswj version ntawm 17-4PH.
Yeeb Nkab, Phaj, Bar: Sib piv cov khoom daim ntawv mus rau txoj cai Specification
Qhov no yog qhov feem ntau ntawm cov ntaub ntawv luam tawm 15-5PH tau txais nws tsis raug, thiab qhov twg qhov yuam kev raug nqi koj qhov kev txiav txim tsis lees paub.
Vim li cas Bar Specification tsis npog phaj
AMS 5659 yog qhov tseeb rau puag ncig bar, hlau, forgings, rings thiab extrusion - nws tsis npog tiaj tus - cov khoom dov. Daim ntawv, sawb thiab phaj yog them los ntawmTIAB SA 5862. Seamless thiab welded tubing yog muab rauASTM A511 Cov Lus Qhia Tshwj Xeeb, nrog AMS 5659 thov los ntawm kev pom zoo lossis rau cov neeg siv khoom tshwj xeeb. Lub qhov rais chemistry zoo ib yam, tab sis cov kev xeem yuav tsum tau ua, cov qauv kev taw qhia thiab cov ntaub ntawv sib txawv.

Yuav Ua Li Cas Kev Kub Kub Kub Teeb Lub Zog, Toughness thiab Cracking Risk
15-5PH yog muab rau hauv Qhov A, ib qho kev daws teeb meem- kho lub xeev mos txaus rau lub tshuab. Cov khoom kawg yog los ntawm ib theem qis-kub aging. Xaiv qhov kub ntawm kev laus yog qhov kev txiav txim siab tshaj plaws hauv qhov kev qhia tshwj xeeb.
H900 rau H1150 ntaiv

Tus nqi yog qhov tsawg kawg nkaus teev rau AMS 5659 / ASTM. Raws li kev laus kub nce, lub zog poob thiab elongation, toughness thiab SCC kuj nce. Ntev -lub sijhawm ua haujlwm kub yuav tsum nyob ntawm lossis qis dua li 315℃.
Qhov xwm txheej A yog lub xeev Machining, tsis yog Lub Xeev Kev Pabcuam
Mob A yog untempered martensitic nrog tsawg puas toughness thiab tsis zoo SCC kuj; nws yuav tsum tsis txhob yog ib feem ntawm qhov kawg mob. Npaj cov kab ke raws li: lub tshuab ntxhib hauv qhov xwm txheej A, hnub nyoog, tshuab tiav. Kev hloov pauv yog kwv yees li 0.05% rau H900 thiab 0.10% rau H1150.
15-5PH yeeb nkab: Qhov ntau thiab tsawg, Kev xa khoom thiab kev txwv
15-5PH tubing yog tsim los rau ASTM A511 hauv ob qho tib si seamless thiab welded-thiab-txoj kev, los ntawm qhov ntsuas me me txog li 500 hli OD, phab ntsa 1-25 hli nyob ntawm txoj kab uas hla; txoj kab uas hla loj dua yog ua -kom xaj. Yuav luag tag nrho cov tubing yog nkag rau hauv Hom A thiab hnub nyoog tom qab tsim. Nws yog hlau nplaum nyob rau hauv txhua yam mob, yog li MPI ua haujlwm ncaj qha rau ntawm qhov chaw tiav.
15-5PH Phaj: Thickness Range thiab Flat Rolled Supply
Phaj thiab daim ntawv mus rau AMS 5862 tuaj txog hauv Kev Kho Mob A ntawm kwv yees li 38 HRC qhov siab tshaj plaws, los ntawm cov ntawv nyias ~ 0.5 hli txog rau phaj ~ 100 hli, dav txog ~ 1500 hli thiab ntev txog 6000 hli, txiav - mus rau - qhov loj me muaj. Phaj yog hla- dov los ntawm ntu tuab - raws nraim qhov twg delta-ferrite stringers daim ntawv hauv 17-4PH - yog li rau ib feem ntawm nws cov tuab, cov khoom sib hloov txiav txim siab ciaj sia.
Delta Ferrite thiab Transverse Toughness: Qhov Tiag Tiag Qhia Txog 15-5PH
Dab tsi Chromium thiab Nickel Ua hauv Martensitic Matrix
Nyob rau hauv ib tug martensitic stainless hlau, chromium stabilizes ferrite thiab npib tsib xee stabilizes austenite. 17-4PH's chromium- nplua nuj tshuav txhawb delta ferrite stringers ua raws li cov kev taw qhia ua hauj lwm - tawg- pib qhov chaw nyob rau hauv -thick.
15-5PH txo qis chromium rau 14.0-15.5% thiab nce npib tsib xee rau 3.5-5.5%, ua kom muaj cov qauv isotropic ntau dua. VAR/ESR remelting tshem tawm sulfide inclusions. Tshaj tawm transverse Charpy qhov tseem ceeb rau 15-5PH khiav roughly 30-50% saum toj 17-4PH ntawm qhov sib npaug.
Qhov Zoo Tshaj Plaws ploj mus
- Daim ntawv nyias thiab zoo hlau:ceev solidification tawm me ntsis chav rau delta ferrite; cov qib yog nyob ze rau kev sib hloov thiab 17-4PH yog pheej yig dua.
- Ntshiab longitudinal load ntawm ib tug me me seem:qhov txiaj ntsig transverse tsis muaj cov ntaub ntawv thauj khoom los ua.
- Kev pabcuam kub:15-5PH yog lub siab- lub zog alloy ntawm ambient thiab nruab nrab siab kub, tsis yog kub-resisting alloy (≈315℃qab nthab).
- Los ntawm corrosion:15-5PH ua tau zoo ntawm 304 qib thiab meej meej zoo dua 400-series martensitic qib, tab sis nws tsis yog hloov pauv rau 316 lossis qib duplex hauv high-chloride lossis muaj zog oxidising acid.

FAQ
Q1: Puas yog 15-5PH yeeb nkab muaj zog dua 316L yeeb nkab?
Yog lawm, los ntawm qhov dav dav - 15-5PH H1025 tawm los yog li 1000 MPa piv rau ~ 170–310 MPa rau 316L. Tab sis 316L yeej ntawm formability thiab tsis zoo corrosion nyob rau hauv ntau yam xov xwm; 15-5PH yog xaiv qhov twg lub zog- rau qhov hnyav thiab hardness tseem ceeb.
Q2: Kuv puas tuaj yeem hloov 17-4PH rau 15-5PH yeeb nkab?
Tsuas yog tias tus qauv tsim tsis tso siab rau kev hloov pauv lossis luv luv -transverse toughness lossis loj -section uniformity. 17-4PH tuaj yeem nqa delta-ferrite uas ua rau cov lus qhia tsis muaj zog. Yog tias daim duab hu tawm 15-5PH, tsis txhob sib pauv yam tsis muaj kev kos npe kos npe rau engineering-tawm - lub npe qib tsis yog tag nrho cov lus qhia.
Q3: Lub tshav kub twg- kho mob tiv thaiv chloride kev nyuaj siab corrosion zoo tshaj?
H1150, tshaj - laus laus, muab qhov siab tshaj plaws SCC qhov pib kev nyuaj siab thiab yog kev taw qhia- ywj siab vim tsis muaj ferrite stringers. H900 yog qhov rhiab tshaj plaws.
Q4: Dab tsi tus qauv npog 15-5PH yeeb nkab?
Cov yeeb nkab / raj feem ntau muab rau ASTM A511 (seamless mechanical tubing) lossis aerospace spec AMS 5659 / AMS 5862, lossis rau cov neeg siv khoom tshwj xeeb; Phaj yog ASTM A693 (XM-12), bar ASTM A564, forgings ASTM A705.
Q5: Puas yog kev laus cuam tshuam cov yeeb nkab qhov ntev?
Tsawg kawg. Kev laus yog qhov qis -tej dej nag lossis daus, tsis yog theem hloov pauv, yog li kev hloov pauv me me. Cov txheej txheem kev coj ua yog tshuab rau hauv Cov Cai A thiab hnub nyoog kawg, uas yog vim li cas "Txoj Cai A + hnub nyoog rau H1025" yog ib txoj hauv kev muab khoom ntau.
