Ntsiab nta
1. Siab zog thiab hardness: 17-4 PH tuaj yeem ua tiav lub zog thiab tawv heev los ntawm kev kho nag lossis daus, ua rau nws tsim nyog rau cov ntawv thov uas xav tau lub zog siab.
2. Zoo Corrosion Resistance: Txawm hais tias tsis zoo li corrosion-resistant li austenitic stainless hlau zoo li 304 thiab 316, nws tseem muaj qhov zoo corrosion kuj nyob rau hauv feem ntau ib puag ncig.
3. Zoo Weldability: Nws tuaj yeem welded siv ntau yam txheej txheem vuam. Kev kho cua sov tom qab vuam yog pom zoo kom ua tiav cov khoom zoo.
4. Zoo Machinability: Nws muaj cov machinability zoo nyob rau hauv cov kev daws teeb meem-kho thiab tuaj yeem txhim kho cov cuab yeej cuab tam tom qab kev kho cua sov.
Tom qab tsim nyog los nag lossis cua kub kho, 17-4 PH stainless hlau tuaj yeem ua tiav cov khoom siv hauv qab no:
Tensile zogUa haujlwm siab: 930-1310 MPa (135-190 ksi)
Yield zogUa haujlwm siab: 725-1100 MPa (105-160 ksi)
Elongation: 10-20%
Kev txo qis ntawm cheeb tsamYog ': 40-60%
Hardness: HRC 28-38
