17-4PH alloy yog cov hlau tsis xeb uas tau ua los ntawm cov hlau tsis xeb uas muaj tooj liab, niobium, thiab tantalum. Cov yam ntxwv: Tom qab kev kho cua sov, cov khoom ua kom pom cov khoom siv kho tshuab zoo dua, ua tiav lub zog compressive txog li 1100-1300 MPa (160-190 ksi). Qib no tsis haum rau kev siv ntawm qhov kub tshaj 300º C (572º F) lossis qhov kub qis heev. Nws qhia tau tias muaj kev tiv thaiv corrosion zoo hauv atmospheric thiab dilute acid lossis ntsev ib puag ncig, sib piv rau 304, thiab zoo dua li ferritic steel 430.

Cov Qib Kev Kho Mob Kub thiab Kev Sib Txawv ntawm Kev Ua Haujlwm: Qhov sib txawv ntawm17-4PHyog nws qhov yooj yim ntawm kev kho cov qib zog los ntawm kev hloov pauv hauv cov txheej txheem kho cua sov. Kev hloov pauv mus rau martensite thiab kev laus ua kom tawv yog txoj hauv kev tseem ceeb ntawm kev ua kom muaj zog. Cov qib kho cua sov feem ntau hauv kev ua lag luam suav nrog H1150D, H1150, H1025, thiab H900.Qee tus neeg siv khoom qhia tias xav tau cov khoom siv 17-4PH thaum lub sijhawm yuav khoom, uas yuav tsum tau kho cua sov. Vim tias qib kev kho cua sov sib txawv, cov xwm txheej siv sib txawv thiab cov kev xav tau cuam tshuam yuav tsum tau ua tib zoo sib txawv. Kev kho cua sov ntawm 17-4PH muaj ob kauj ruam: kev kho cov tshuaj thiab kev laus. Qhov kub ntawm kev kho cov tshuaj yog tib yam rau kev txias sai, thiab kev laus kho qhov kub thiab tus lej ntawm cov voj voog laus raws li lub zog xav tau.
Cov ntawv thov:
Vim nws cov khoom siv kho tshuab zoo heev thiab tiv taus xeb, 17-4PH siv dav hauv kev lag luam xws li petrochemicals, nuclear fais fab, aerospace, tub rog, marine, automotive, thiab kev kho mob. Yav tom ntej, nws xav tias yuav muaj kev lag luam zoo ib yam li duplex steel.
