17-4PH ANNEALED STAINLESS STEEL

Alloy 17-4 yog chromium-tooj ​​liab nag lossis daus hardening stainless hlau uas yog siv rau daim ntaub ntawv uas yuav tsum tau muaj zog thiab ib tug nruab nrab ntawm corrosion kuj. Nws yog ib qho ntawm feem ntau siv los nag lossis daus hardening qib, raws li nws muaj zog hardness txog li 572 ° F thaum pom zoo corrosion kuj nyob rau hauv tag nrho cov tshav kub kho mob. Alloy 17-4 muaj peev xwm tiv taus atmospheric corrosion los yog diluted acid ntsev qhov twg nws corrosion kuj yog sib npaug rau Alloy 304 los yog 430. Alloy 17-4 tuaj yeem kho cua sov rau ntau qhov kub kom tsim tau ntau yam khoom. Nws cov khoom siv kho tshuab tuaj yeem ua kom zoo nrog kev kho cua sov qhov twg muaj zog heev tawm los mus txog 180 ksi tuaj yeem ua tiav. Alloy 17-4 yuav tsum tsis txhob siv ntawm qhov kub siab tshaj 572 ° F lossis ntawm qhov kub qis heev.

17-4 Stainless hlau
Qhov no martensitic nag lossis daus hardening stainless hlau muaj kev sib xyaw ua ke ntawm siab hardness thiab lub zog tom qab tsim kho cua sov. Nws kuj muaj qhov zoo sib xws corrosion thiab kub tsis kam rau qib 304. Ob lo lus "Type 630" thiab "17-4PH" hais txog tib qib.
