1.4568 Stainless hlau yog dab tsi?

1.4568 stainless hlau, feem ntau hu ua 631 lossis 17-7PH (UNS S17700), yog ib nrab -austenitic nag lossis daus- cov hlau tsis muaj zog. Nws yog lub npe hu rau nws lub peev xwm tshwj xeeb los tsim nyob rau hauv ib qho muag muag, zawm mob thiab tom qab ntawd kub hnyiab tau- kho kom ua tiav lub zog thiab hardness, nrog rau kev ua haujlwm zoo corrosion. Qhov no ua rau nws zoo tagnrho rau aerospace springs, high-stress fasteners, thiab cov cuab yeej kho mob.

 

Cov nag lossis daus no ntau yam - qib hardening yog tus qauv raws li cov txheej txheem thoob ntiaj teb tseem ceeb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4568 / 17-7PH

Siab zog nrog zoo Ductility:Muaj peev xwm ua tau lub zog tensile tshaj 1200 MPa tom qab nag lossis daus hardening thaum khaws cov khoom siv tau zoo.

Zoo Fatigue thiab Caij nplooj ntoos hlav Properties:Dav siv rau cov springs, diaphragms, thiab lwm yam khoom uas xav tau kev qaug zog thiab elastic zog.

Zoo Corrosion Resistance:Piv rau Hom 304 stainless hlau, ua rau nws tsim nyog rau daim ntawv thov uas yuav tsum tau muaj zog thiab nruab nrab corrosion kuj.

 

Cov ntawv thov tseem ceeb:

Aerospace:Bellows, springs, fasteners, thiab structural Cheebtsam.

Kev kho mob:Cov cuab yeej phais, orthopedic implants, thiab cov cuab yeej kho hniav.

Kev ua tshuaj lom neeg:Valve qhov chaw thiab cov twj tso kua mis xav tau lub zog thiab corrosion kuj.

Cov cuab yeej Precision:Cov khoom tseem ceeb uas yuav tsum tau muaj qhov ruaj khov thiab lub zog siab.

 

Dab tsi yog qhov kev kho cua sov ua ntu zus rau 17-7PH (1.4568)?
Cov kev kho mob tshaj plaws yog covTIAB SA 1050mob. Ua ntej, cov khoom siv yogtshuaj khontawm 1040 ° C thiab txias sai heev (Cov Cai A). Nws yog cestxiaslos ntawm cua sov mus rau 760 ° C, tuav, thiab txias rau chav sov li ntawm 1 teev. Thaum kawg, nws yogmuaj hnub nyoog tawvntawm 565 ° C rau 90 feeb. Cov kab ke no hloov cov qauv austenitic mus rau martensitic thiab tom qab ntawd precipitates hardening theem, ua tiav lub zog siab. Cov cua txias sib txawv thiab kev laus kub ua kom muaj zog ntau ntau.

 

17-7PH piv rau 17-4PH li cas ntawm cov khoom thiab kev siv?
Ob leeg yog nag lossis daus- qib hardening, tab sis 17-7PH yog ib nrab austenitic thaum 17-4PH yog martensitic. 17-7PH feem ntau muaj qhov zoo dua formability nyob rau hauv lub annealed mob thiab muaj peev xwm ua tau ntau zog ntau zog (tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov caij nplooj ntoos hlav) nrog zoo heev qaug zog tiv thaiv. 17-4PH feem ntau yog zoo dua rau kev siv lub caij nplooj ntoos hlav qhov chaw. 17-7PH yog qhov zoo dua rau cov ntu nyias thiab tsim cov khoom xws li cov springs thiab hauv qab.
