Dab tsi txiav txim siab qhov corrosion kuj ntawm txias -rolled round bar?
Feem ntau txiav txim siab los ntawm cov khoom muaj pes tsawg leeg (xws li, chromium thiab nickel oxide films tsim nyob rau hauv stainless hlau), nto zoo kuj plays lub luag hauj lwm.
Kev ua haujlwm hardening cuam tshuam li cas rau kev ua haujlwm?
Advantage: Muaj zog thiab hardness; Disadvantage: Txo plasticity, ua rau qhov nyuaj ntawm kev ua haujlwm tom ntej (xws li khoov thiab txiav).
Qhov tsis zoo thiab kev daws teeb meem
Ua rau thiab kev daws teeb meem rau Nto Scratches
