Kev cai Chrome Molybdenum 42CrMo4 alloy hlaupeev casting khoomrau xauv nuv ntawm tsheb nrogelectrophoresis nto kho.
42CrMo4 (1.7225) los ntawm kev qhia tshwj xeeb ntawm EN 10083-3, uas feem ntau yog cua sov kho los ntawm QT (Queching + Tempering), yog dav siv los tsim peev castings. Nws muaj lub zog siab, siab toughness, zoo hardenability, temper brittleness, siab qaug zog txwv, zoo cuam tshuam tom qab quenching thiab tempering, thiab zoo kub tsis tshua muaj cuam tshuam toughness. Qib sib npaug ntawm 42CrMo4 yog 4140 (ASTM, USA) thiab 42CrMo (GB/T 3077, Tuam Tshoj)

Siv covpeev casting txheej txheem, RMC casting foundry muaj peev xwm ua tau raws li cov khoom siv tshwj xeeb raws li ASTM, SAE, AISI, ACI, DIN, EN, ISO, thiab GB qauv. Peb muaj ntau tshaj 100 qhov sib txawv ferrous thiab non-ferrous alloys uas peb nrum qhov chaw siv cov qauv tsim qauv. Peb dimensionally thiab geometrically complex peev castings yog tsim los rau net zoo, txo qhov yuav tsum tau rau lwm yam machining.
Chromium-molybdenum cam khwb cia hlau yog dav siv nyob rau hauv kev lag luam teb nrog kuj zoo heev mechanical zog. Qhov sib ntxiv ntawm molybdenum rau chromium hlau tuaj yeem ua rau kom lub zog ntawm cov hlau castings tsis muaj qhov cuam tshuam loj rau qhov cuam tshuam ntawm cov cam khwb cia hlau. Tsis tas li ntawd, chromium-molybdenum cam khwb cia hlau muaj qhov kub thiab txias kev ua haujlwm zoo heev. Tom qab quenching thiab tempering los yog normalizing kev kho cua sov, chromium-molybdenum cam khwb cia hlau tuaj yeem tau txais cov khoom zoo heev.
Molybdenum tuaj yeem txhim kho lub hardenability ntawm cam khwb cia hlau thiab txo cov temper brittleness ntawm cam khwb cia hlau. Chromium-molybdenum cam khwb cia hlau yog siv rau loj-section castings thiab steel castings uas yuav tsum tau sib sib zog nqus hardening.
