42CrMo yog cov khoom zoo siab alloy steel, feem ntau yog siv los ua cov khoom siv hluav taws xob muaj zog. Nws cov tshuaj muaj pes tsawg leeg suav nrog 0. 0. ntawm cov sulfur, 0.90 1.20% chromium molybdenum, 0.15 txog 0.25%. Kev sib xyaw ntawm cov ntsiab lus no muab 42CrMo zoo zog, hardness, corrosion kuj thiab hnav tsis kam. Tshwj xeeb, nws lub zog tawm los yog 930MPa, lub zog tensile yog 1080MPa, elongation yog 12%, thiab hardness tuaj yeem ncav cuag 217HBW. Cov khoom no ua rau nws tsim nyog rau kev tsim cov khoom siv muaj zog, hnav-tiv taus cov khoom siv, xws li cov ncej, lub zog, txuas cov pas nrig, thiab lwm yam. Tsis tas li ntawd, 42CrMo kuj muaj qhov zoo weldability, ua haujlwm tau zoo thiab kev kho cua sov, thiab tuaj yeem siv rau hauv ntau hom kev kho cua sov kom tau txais kev ua haujlwm sib txawv. Yog li ntawd, 42CrMo yog dav siv nyob rau hauv hnyav machinery, tsheb, nkoj, aerospace thiab lwm yam teb, xws li tsheb tsav ncej, Marine ncej, txuas pas nrig ntawm aircraft cav, vibrating npo thiab hais txog.
Hais txog cov qauv thiab kev faib tawm, 42CrMo yog txhais raws li chav kawm ntawm cov hlau raws li German DIN tus qauv thiab Suav GB / T3077 tus qauv, qee zaum hu ua hlau tuag lossis cov cuab yeej hlau. Nws yog tsuas yog siv los tiv thaiv kev ua haujlwm muaj zog nyob rau hauv kev kub siab, kub thiab kub ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv aerospace, shipbuilding, tshuaj lom neeg kev lag luam, machinery thiab lwm yam teb muaj ntau yam kev siv.
42CrMo seamless steel yeeb nkab yog siv los ua cov khoom siv hlau vim nws lub zog siab thiab tawv, nrog rau kev ua kom zoo dua brittleness permeability. Nws cov xwm txheej hauv steel zoo ib yam li tus lej 345, uas sawv cev rau cov chav kawm zoo, piv txwv li cov ntaub ntawv uas tsis tas yuav muaj kev cuam tshuam. 42CrMo nws tus kheej belongs rau 42 series, thiab 42CrMo4 yog ib qho ntawm cov qib hardened thiab tempered steel hauv EN10083 tus qauv.
Nyob rau hauv cov ntsiab lus, 42CrMo yog ib tug ntau yam alloy structural steel nrog zoo heev tag nrho cov neeg kho tshuab zog, zoo hardenability, thiab ib tug ntau yam ntawm daim ntawv thov nyob rau hauv ntau yam kev lag luam teb.
