Taw qhia
Qhov kev thov rau cov khoom muaj zog, corrosion-resistant cov ntaub ntawv nyob rau hauv aerospace, marine, thiab tshuaj industries tau coj mus rau lub loj hlob muaj koob meej ntawmASTM A564 Hom 630 stainless hlau round bar, feem ntau hu ua17-4 PAB or UNS S17400. Qhov no nag lossis daus-hardening martensitic stainless hlau muab qhov zoo sib npaug ntawm lub zog, toughness, thiab corrosion kuj.
Hauv tsab xov xwm no, SAKY STEEL qhia txog cov yam ntxwv tseem ceeb, kev qhia tshwj xeeb, kev siv, thiab kev muaj peev xwm ntawm cov khoom siv17-4PH round bars, muab kev nkag siab rau engineers, buyers, thiab manufacturers thoob plaws industries.
ASTM A564 Hom 630 yog dab tsi17-4PH Stainless hlau?
ASTM A564 Hom 630yog tus qauv specification rau kub-thiab txias-tiav hnub nyoog-hardened stainless hlau tuav thiab cov duab, feem ntau hu ua17-4 nag lossis daus hardening stainless hlau. Cov hlau no yog tsim los ntawm chromium, npib tsib xee, thiab tooj liab, nrog ntxiv niobium los txhim kho lub zog los ntawm nag lossis daus hardening.
Cov khoom tseem ceeb:
