Sncm 630 Khoom

SNCM630 cov khoom siv yog cov hlau ua haujlwm siab uas muaj ntau yam khoom zoo heev, ua rau nws tsim nyog rau ntau yam kev thov.

Tshuaj muaj pes tsawg leeg:
Cov tshuaj muaj pes tsawg leeg ntawm SNCM630 steel feem ntau suav nrog npib tsib xee (Ni), chromium (Cr), molybdenum (Mo), thiab lwm yam. Nws muaj ntau npaum li cas ntawm npib tsib xee, feem ntau yog nyob ib ncig ntawm 1.5% mus rau 2.0%. Nickel txhim kho cov hlau qhov toughness, ductility, thiab corrosion kuj. Chromium, tam sim no nyob rau hauv ib feem ntawm kwv yees li ntawm 0.4% mus rau 0.7%, pab rau hardness, hnav tsis kam, thiab oxidation kuj. Molybdenum, nrog rau cov ntsiab lus ntawm 0.15% mus rau 0.3%, ntxiv dag zog thiab hardenability. Tsis tas li ntawd, SNCM630 kuj tseem muaj cov khoom me me ntawm manganese (Mn), silicon (Si), sulfur (S), thiab phosphorus (P), uas tau ua tib zoo tswj xyuas kom ntseeg tau tias cov khoom siv kho kom zoo thiab zoo.

Mechanical Properties:

• Lub zog muaj zog: SNCM630 cov ntaub ntawv nthuav tawm lub zog tensile siab heev, uas tuaj yeem muaj li ntawm 1000 MPa txog 1200 MPa. Qhov no ua rau nws muaj peev xwm tiv taus cov khoom hnyav thiab kev ntxhov siab yam tsis ua haujlwm.

• Zoo Ductility: Txawm tias nws lub zog siab, SNCM630 kuj qhia tau zoo ductility, cia nws deformed yam tsis muaj cracking. Qhov feem pua ​​​​elongation tuaj yeem nyob ib puag ncig 12% mus rau 15%, qhia tias nws muaj peev xwm ua rau cov yas deformation.

• Zoo heev Toughness: Cov khoom muaj zoo heev toughness, ua rau nws nqus zog thiab tiv thaiv puas. Qhov no yog qhov tseem ceeb heev rau cov ntawv thov uas cov hlau yuav raug cuam tshuam los yog poob siab.

• Enhanced Hardness: Los ntawm kev kho cua sov kom zoo, SNCM630 tuaj yeem ua tiav qib siab hardness, feem ntau nyob rau hauv thaj tsam ntawm 250 HB (Brinell hardness) txog 350 HB. Qhov hardness no muab kev tiv thaiv rau hnav thiab puas.

• Zoo Fatigue Resistance: SNCM630 muaj kev tiv thaiv kev qaug zog zoo heev, txhais tau tias nws tuaj yeem tiv taus rov qab thauj khoom thiab thauj mus los yam tsis muaj kev puas tsuaj loj hauv kev ua haujlwm.

Kev kho cua sov:
Kev kho cua sov ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom ntawm SNCM630 cov khoom. Quenching thiab tempering yog feem ntau siv cov txheej txheem kho cua sov. Quenching muaj cua sov cov hlau mus rau qhov kub thiab txias thiab tom qab ntawd maj mam txias nws hauv qhov nruab nrab quenching xws li roj lossis dej. Qhov txias txias no ua rau cov hlau tawv. Tom qab ntawd tempering yog ua los txo cov brittleness ntawm quenched steel thiab txhim kho nws toughness. Cov kev kho cua sov tsis zoo, suav nrog qhov kub thiab txias, lub sijhawm, thiab tus nqi cua txias, yuav tsum tau ua tib zoo tswj kom ua tiav cov khoom siv tshuab uas xav tau.

Daim ntawv thov:

• Automotive Kev Lag Luam: SNCM630 yog siv dav hauv kev lag luam tsheb rau kev tsim cov khoom tseem ceeb xws li iav, ncej, thiab crankshafts. Cov khoom no yuav tsum muaj lub zog siab, ua haujlwm ntev, thiab hnav tsis kam tiv thaiv kev ua haujlwm hnyav ntawm cov cav thiab kev sib kis.

• Kev lag luam Machinery: Hauv kev siv tshuab, SNCM630 yog siv los ua cov khoom siv tshuab xws li bearings, bolts, thiab txiv ntseej. Nws cov khoom siv kho tshuab zoo heev ua rau nws haum rau cov ntawv thov uas yuav tsum muaj lub zog siab thiab kev ntseeg siab.

• Aerospace Kev Lag Luam: Kev lag luam aerospace kuj ua rau siv SNCM630 rau qee yam khoom siv vim nws lub zog-rau-qhov hnyav piv thiab tsis kam ua rau qaug zog thiab corrosion.

• Roj thiab Roj Kev Lag Luam: Hauv kev lag luam roj thiab roj, SNCM630 tuaj yeem pom nyob rau hauv daim ntaub ntawv xws li laum dab tshos, tubing, thiab casing. Nws lub zog thiab kev tiv thaiv corrosion yog qhov tseem ceeb rau kev tiv thaiv ib puag ncig hnyav uas tau ntsib hauv kev tshawb nrhiav roj thiab roj thiab kev tsim khoom.

Qhov zoo:

• Superior Mechanical Properties: SNCM630 muaj kev sib xyaw ua ke ntawm lub zog siab, toughness, ductility, thiab hardness, ua rau nws sawv ntawm lwm cov hlau.

• Corrosion Resistance: Lub xub ntiag ntawm nickel thiab chromium muab kev tiv thaiv corrosion zoo, tshwj xeeb tshaj yog nyob rau qee qhov chaw.

• Hardenability: Cov ntsiab lus alloying nyob rau hauv SNCM630 muab nws zoo heev hardenability, tso cai rau uniform hardness thoob plaws hauv cov khoom.

• Weldability: Nrog cov txheej txheem tsim nyog thiab kev ceev faj, SNCM630 tuaj yeem welded, muab kev yooj yim hauv fabrication thiab sib dhos.

• Lub neej ua haujlwm ntev: Vim nws cov khoom siv kho tshuab zoo heev thiab tsis kam hnav thiab qaug zog, SNCM630 cov khoom feem ntau muaj lub neej ua haujlwm ntev, txo cov nqi kho thiab hloov pauv.

Hauv kev xaus, SNCM630 cov khoom yog cov hlau zoo kawg nkaus nrog cov tshuaj sib npaug zoo thiab cov khoom siv zoo heev. Nws versatility thiab kev ua tau zoo ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hauv ntau yam lag luam. Txawm li cas los xij, kev tuav zoo, kev ua, thiab kev kho cua sov yog qhov tseem ceeb kom paub txog nws lub peev xwm thiab ua kom zoo thiab kev ntseeg siab ntawm cov khoom kawg.
