15-5 PH stainless hlau yog martensitic nag lossis daus-hardening stainless hlau nrog kwv yees li 15% Chromium thiab 5% Nickel. Nws muaj lub zog siab, siab hardness, thiab zoo heev corrosion kuj. Lub zog tuaj yeem nce ntxiv los ntawm kev kho cua sov ib leeg. Piv rau 17-4 PH, nws muaj qhov zoo dua transverse toughness thiab ductility; zoo mechanical zog nyob rau hauv loj cross-section, thiab zoo forgeability. Nws yog yooj yim weldable. Nws tuaj yeem raug machined nyob rau hauv ib qho ntawm ob peb Thermal Conditions muaj rau qib no.
