1.4546 Stainless hlau yog dab tsi?

1.4546 stainless hlau, feem ntau hu ua XM-12 lossis 15-5PH (UNS S15500), yog martensitic nag lossis daus-hardening stainless hlau zoo ib yam li 17-4PH tab sis muaj cov sib txawv me ntsis los txhim kho toughness thiab transverse mechanical zog. Nws paub txog nws lub zog siab, zoo corrosion kuj piv rau Hom 304, thiab zoo heev toughness nyob rau hauv ob qho tib si longitudinal thiab transverse cov lus qhia, ua rau nws zoo tagnrho rau aerospace, tshuaj, thiab high-kev ua tau zoo engineering Cheebtsam.

 

Qhov siab no -lub zog nag lossis daus- qib hardening yog tus qauv raws li cov txheej txheem thoob ntiaj teb tseem ceeb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4546 / 15-5PH

High Strength nrog Zoo Toughness:Muab lub zog tensile tshaj 1300 MPa tom qab kev laus, nrog superior toughness thiab ductility piv rau ntau lwm yam siab -lub zog stainless hlau, tshwj xeeb tshaj yog nyob rau hauv lub transverse kev taw qhia.

Zoo Corrosion Resistance:Muab kev tiv thaiv corrosion zoo ib yam li Hom 304 stainless hlau, haum rau nruab nrab corrosive ib puag ncig.

Precipitation Hardening:Nws tuaj yeem raug siv rau hauv cov tshuaj -kho (softer) mob thiab tom qab ntawd muaj hnub nyoog mus rau lub zog siab nrog kev cuam tshuam tsawg heev.

 

Cov ntawv thov tseem ceeb:

Aerospace:Cov khoom siv hauv av tsaws, turbine blades, fasteners, thiab cov khoom siv uas xav tau lub zog siab - rau - qhov hnyav piv.

Tshuaj thiab Petrochemical:Valves, twj tso kua mis shafts, thiab fittings raug corrosive media.

Roj & Roj:Cov cuab yeej downhole, cov cuab yeej ntsuas, thiab siab -siab li qub.

Kev kho mob:Cov cuab yeej phais thiab orthopedic implants xav tau lub zog thiab biocompatibility.

 

Qhov txawv ntawm 15-5PH (1.4546) thiab 17-4PH (1.4542) yog dab tsi?
Ob leeg yog nag lossis daus- hardening martensitic stainless hlau, tab sis 15-5PH muaj chromium qis me ntsis (14–15.5% vs. 15-17.5%) thiab cov ntsiab lus ntau dua nickel. Qhov kev sib xyaw ua ke no, nrog rau kev siv lub tshuab nqus tsev feem ntau siv rau 15-5PH, ua rau cov hlau huv nrog tsawg dua, muab 15-5PH zoo dua transverse toughness thiab ductility. 15-5PH feem ntau yog xaiv rau kev siv aerospace thiab kev kho mob tseem ceeb uas cov khoom isotropic tseem ceeb.

 

15-5PH feem ntau yog kho li cas?
Cov txheej txheem kev kho cua sov suav nrogtshuaj khontawm 1038℃± 15 degree, ua raws li kev ua kom txias sai (cua sov lossis roj quench) kom ua tiav qhov xwm txheej A (mos, machinable xeev). Nws yog ceslausntawm qhov kub thiab txias (piv txwv li, 482℃rau H900, 621℃rau H1150) kom precipitate hardening theem thiab ua tiav qhov xav tau lub zog thiab toughness. Ob chav laus yog qee zaum siv los ua kom zoo dua qub thiab ua kom muaj kev ruaj ntseg.
