Khoom Description
Chromoly Steel Tubing yog tsim los ntawm siab- cov ntaub ntawv zoo, suav nrog 4130 thiab 4140. AISI 4130 thiab AISI 4140 yog cov chromium feem ntau siv- qib molybdenum steel hauv kev siv tshuab engineering.
Peb 4130 chromium-molybdenum hlab yog forged ntawm qhov kub thiab txias ntawm 950℃thiab 1230 degree, nthuav tawm cov khoom zoo heev ntawm ob chav tsev thiab qhov kub siab. Lawv kuj muaj cov ntsiab lus carbon tsawg, ua rau lawv yooj yim rau vuam, thiab ua haujlwm zoo heev, yooj yim khoov, vuam, drilling, thiab lwm yam.
4140 muaj cov machinability tsis zoo thiab weldability, yuav tsum tau preheating ua ntej vuam thiab kev kho cua sov tom qab vuam. Txawm li cas los xij, 4140 muaj qhov ua tau zoo tshaj - qhov kub thiab txias, tseem tsis tau tawg rau 2000 teev ntawm 600℃.
