Gnee 4140 Hlau Precision Av Bar Qhia
4140 Alloy Precision Av Bar
4140 Precision Av Bar yog lub siab-zog chromium-molybdenum sib tsoo ntawm kev sib tsoo ntawm cov neeg txias lossis sib npaug rau cov contectents ntawm cov ntsiab lus tseem ceeb. Nws cov cim kev ua haujlwm muaj xws li:
Peb Cov Qauv Tseem Ceeb
Qhov kawg lub zog thiab hnav tsis kam
Tom qab quenching thiab tempering tshav kub (q & t), xws li txhaj tshuaj yeeb yaj kiab ntau dua lossis sib npaug ntawm cov khoom siv sib npaug
Microstructure homogeneity
Precision grinding eliminates surface microcracks and decarburization layers, and the fatigue life is increased by 40-60% compared with ordinary hot-rolled bars (10⁷ cycles of stress>450 mpa) .
Xoom Ua, Npaj Yuav Siv
Kev tiv thaiv txoj kab uas hla txoj kab uas hla mus rau H6 / H7 (xws li ∅25mm), ncaj} 0}} 0 {} 0 {}) Kev sib tsoo cov nqi, txo tus nqi los ntawm 30%.
