JIS G 4103-1979 SNCM 815 SNCM 25

JIS G 4103-1979 txhais cov lus qhia tshwj xeeb rau cov hlau alloy, suav nrog SNCM815 thiab SNCM25. Cov ntaub ntawv no ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam.

SNCM815 paub txog nws cov cuab yeej tshwj xeeb. Nws muaj lub zog siab thiab toughness, ua rau nws tsim nyog rau kev thov xws li lub zog, ncej, thiab cov tshuab ua haujlwm hnyav. Cov ntsiab lus alloying hauv SNCM815 ua rau nws zoo heev hnav tsis kam thiab qaug zog. Qhov no ua rau nws tiv taus cov khoom hnyav thiab rov ua dua kev ntxhov siab yam tsis ua haujlwm. Tsis tas li ntawd, SNCM815 muaj qhov zoo hardenability, tso cai rau cov tawv tawv tsis sib xws thoob plaws hauv cov khoom thaum kho cua sov kom zoo.

SNCM25, ntawm qhov tod tes, muaj cov txheej txheem sib txawv. Nws muaj zoo ductility thiab toughness, nrog rau nruab nrab lub zog. Qhov no ua rau nws haum rau cov ntawv thov uas cuam tshuam tsis kam thiab formability tseem ceeb. SNCM25 feem ntau yog siv los tsim cov khoom siv thiab cov khoom uas yuav tsum tau khoov lossis shaping. Cov alloy kuj muaj kev tiv thaiv corrosion zoo, uas yog qhov zoo hauv qee qhov chaw.

Ob leeg SNCM815 thiab SNCM25 tau ua tib zoo tsim kom tau raws li cov kev cai tshwj xeeb ntawm kev lag luam sib txawv. Lub Japanese Industrial Standards (JIS) ua kom ntseeg tau zoo thiab ua tau zoo ntawm cov ntaub ntawv no. Cov neeg tsim khoom tso siab rau cov qauv no los tsim cov khoom lag luam txhim khu kev qha thiab ruaj khov.

Ntxiv nrog rau lawv cov khoom siv kho tshuab, cov alloys tuaj yeem raug kho cua sov kom ntxiv dag zog rau lawv cov yam ntxwv. Cov txheej txheem kho cua sov xws li quenching thiab tempering tuaj yeem txhim kho hardness, lub zog, thiab toughness. Qhov no tso cai rau kev hloov kho ntawm cov ntaub ntawv kom tau raws li cov kev xav tau tshwj xeeb ntawm kev siv sib txawv.

Kev siv SNCM815 thiab SNCM25 hauv ntau qhov kev lag luam pab txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm cov tshuab tshuab. Lawv cov khoom tshwj xeeb ua rau lawv muaj txiaj ntsig kev xaiv rau cov engineers thiab cov neeg tsim qauv nrhiav cov ntaub ntawv zoo.

Zuag qhia tag nrho, JIS G 4103-1979 thiab cov alloys SNCM815 thiab SNCM25 ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov hlau alloy. Lawv cov khoom tshwj xeeb thiab cov yam ntxwv ua rau lawv haum rau ntau yam kev siv, ua rau kev nce qib ntawm ntau yam kev lag luam.
