17-4PH Stainless Hlau Bar

17-4 PH stainless hlau (630) yog chromium-tooj ​​liab nag lossis daus hardening stainless hlau cov ntaub ntawv siv rau cov ntawv thov uas yuav tsum tau muaj zog thiab ib nrab ntawm corrosion kuj. Lub zog siab yog tswj kom txog li 600 degrees Fahrenheit (316 degrees Celsius).

 

General Properties

Stainless hlau Alloy 17-4 PH yog nag lossis daus hardening martensitic stainless hlau nrog Cu thiab Nb / Cb ntxiv. Cov qib sib xyaw ua ke siab zog, hardness (txog 572℃F / 300 degree), thiab corrosion kuj.

Cov khoom siv kho tshuab tuaj yeem ua kom zoo nrog kev kho cua sov. Lub zog muaj zog heev txog li 1100-1300 MPa (160-190 ksi) tuaj yeem ua tiav.

Cov qib yuav tsum tsis txhob siv ntawm qhov kub siab tshaj 572℃F (300 degree) lossis qhov kub qis heev. Nws muaj kev tiv thaiv txaus rau atmospheric corrosion los yog hauv cov kua qaub diluted los yog ntsev qhov twg nws corrosion kuj yog sib npaug rau Alloy 304 lossis 430.
