Khoom Description
1.2721 yog cov khoom qib ntawm cov hlau alloy rau cov cuab yeej ua haujlwm txias hauv lub teb chaws Yelemees. Nws yog qhov cuam tshuam resistant steel. Nws belongs rau DIN 17350 tus qauv. Cov ntaub ntawv qib digital tus lej 1.2721. Cov hlau hlau qib W-Nr 50NiCr13 yog ib hom hlau tuag, uas yog siv rau extrusion tuag thiab kub casting tuag. Xws li aluminium ntau lawm, aluminium txiav pwm.
