AISI4130 ASTM 4130 30CrMo SCM430 Seamless steel yeeb nkab
AISI4130 Tuam Tshoj hauv tsev qib 30CrMo yog cov hlau alloy uas muaj chromium thiab molybdenum, nrog lub zog tensile feem ntau siab dua 750MPa.Feem ntau pom nyob rau hauv kev ua lag luam yog tuav thiab tuab daim hlau.Nyias phab ntsa 4130 steel yeeb nkab yuav siv los ua lub tsheb kauj vab lossis tsheb / tsheb npav.Qhov no yog ib tug detachable steel yeeb nkab los ua ke.Nws yog ua los ntawm txias kos seamless carbon steel kav khoov thiab ntsia ib los ntawm ib tug raws li contour ntawm sab hauv ntawm lub carriage.
AISI 4130 seamless steel yeeb nkab muaj peev xwm ua hauj lwm zoo, tsawg ua deformation, thiab zoo heev qaug zog.Nws belongs rau qeb ntawm nruab nrab mus rau siab harden peev xwm steel.Nrog rau kev kho cua sov kom zoo nws kuj tau yooj yim machined.Annealing ASTM 4130 alloy steel muaj ductility zoo heev.AISI 4130 steel feem ntau yog muab raws li puag ncig bar feem ntau nyob rau hauv lub hardened thiab tempered mob.
