17-4PH Stainless hlau yog dab tsi?
17-4PH stainless hlau yog martensitic nag lossis daus- hardening stainless hlau, los yog 630 stainless hlau. Los ntawm kev ntxiv cov ntsiab lus xws li tooj liab (Cu) thiab niobium / columbium (Nb / Cb), thiab los ntawm kev kho cua sov (kev laus), theem tooj liab nplua nuj tuaj yeem ua rau nag lossis daus ntawm qhov kub qis (xws li 480-620 degree), txhim kho nws cov khoom siv kho tshuab. Nws lub zog tawm los tuaj yeem ncav cuag 1100-1300 MPa, thaum tseem muaj kev tiv thaiv corrosion tsis zoo. Nws yog ib qho yooj yim rau txheej txheem thiab tsim, thiab nws lub zog tuaj yeem ua tau zoo heev tom qab kev kho cua sov. Nws yog dav siv nyob rau hauv cov khoom tseem ceeb uas yuav tsum tau muaj zog thiab zoo corrosion kuj nyob rau hauv aerospace, petrochemical, marine engineering, twj thiab li qub, fasteners, thiab lwm yam lag luam.

FAQ
Kuv yuav xaiv qhov kev kho cua sov twg?
H900 yog tus qauv rau lub zog siab tshaj plaws; H1025 / H1075 / H1150 tuaj yeem siv rau kev sib npaug ntawm qhov toughness thiab corrosion kuj.
17-4PH bars tuaj yeem ua tau yooj yim?
Yog lawm, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj -annealed mob; machining tom qab kev laus yuav tsum tau optimized tooling.
Puas yog GNEE tuaj yeem muab cov kab loj loj?
Yog lawm, peb muab cov khoom tuav txog li 300 hli thiab tuaj yeem tsim qhov ntev ntev.
Koj puas muab cov ntawv pov thawj khoom siv (MTC)?
Yog lawm, EN10204 3.1 MTC yog muab rau txhua pawg.
