15H, 17Cr3, 15Cr3 - piav qhia
Hlau rau tshuab qhov uas tsis muaj zog yuav tsum tau, piv txwv li, spindles, pins, camshafts thiab bushings. Weldable, machinable thiab cuttable steel. Weld tsuas yog ua ntej carburizing. Cov hlau zoo ib yam li 20Cr4 tab sis muaj cov khoom siv tsis zoo.
Lub cev thiab mechanical zog
Ntawm no koj tuaj yeem pom cov khoom siv kho tshuab ntawm cov alloys xaiv. Txawm hais tias lawv zoo sib xws, lawv muaj qhov sib txawv kom meej.
